BIOMASS HEATING by CCRES




BIOMASS HEATING


Moving away from fossil fuels, we will need to find alternatives to coal, oil and gas for heating our homes and offices. One obvious solution is biomass - typically in the form of wood.

It is a renewable fuel that truly "grows on trees" and it can be produced locally and sustainably - as long as a new tree is planted for every tree that is cut down. Burning wood biomass emits CO2 through the chimney, but as growing trees absorb CO2 from the atmosphere biomass can be a nearly carbon neutral source of fuel as long as trees are replanted.

Batch log boilers and pellet boilers offer more convenient and efficient ways to heat with wood fuel than traditional stoves.

Related Questions

Can I heat with pellets without using a hopper store?

It is possible to heat with pellets without having a large hopper store connected to a boiler. There are compact pellet boilers - sometimes referred to as pellet stoves with back boilers - which can be filled manually with bags of pellets.

This can be an advantage where there is no space for a hopper store, or where pellets can only be delivered in bags anyway (e.g. because there is no access for a pellet delivery truck).

Can you burn wood biomass without smoke?

Emissions from wood fuel contain virtually no sulphur dioxide and very low levels of nitrous oxides, so won’t cause acid rain. Burning wood cleanly gives off very low amounts of smoke particulates, and many wood-fired appliances are certified for smokeless zones (Defra publish a list of Smoke Control Zones).

It’s important to burn efficiently; use properly seasoned wood (with low moisture content) and make sure that equipment is used properly. Manually fed stoves can produce lots of pollutants if operated badly.

Logs should be burned fiercely with lots of air input until they are almost charcoal, after which the stove can be ‘damped down’. Reducing the air supply too early creates lots of smoke & tar. The key is good ‘secondary combustion’ of the high-energy volatile gases given off by burning wood. Some stoves are fitted with a ‘Lamda’ sensor, to regulate the amount of oxygen added and so optimise efficiency. Avoid burning treated, painted or glued wood, or non-wood waste, as these will give off toxic and polluting gases.

Building regulations require all fuel burners to have a dedicated vent to avoid production of carbon monoxide. The chimney needs an insulated flue to prevent fumes condensing as tar. With complete combustion, wood burns to a small amount of ash, which (unlike coal ash) is an excellent fertiliser.

How do I store wood biomass?

Delivered wood should be stored for at least one year, preferably two, to air-dry the wood to a moisture content below 25%. Bringing logs inside for the last week or so improves them to room dryness. Stoves might be specified to cope with 50% moisture content, but efficiency will suffer. Compressed wood pellet fuel has only about 8% moisture. Manufacturers specify pellets of a certain size, shape and moisture content to ensure reliable operation. Some pellets are produced for power station co-firing, and are not good enough quality for domestic appliances.

The required storage space depends on how big and how well-insulated your home is. A small cottage is likely to need 8 cubic metres (m3) of logs each year, a 3-bedroom house 12m3, and a large detached house 16m3. Pellets have a higher energy content and so take up less than half as much space. Stoves use 0.5 to 1.5kg of pellets per hour, so a 15kg bag should last a few days.

Larger systems can use chipped wood - this allows more automation than logs and is cheaper than pellets. A wood chip boiler heats several buildings at CAT; seasoned wood is delivered, chipped, and stored until it reaches 15% moisture content. For larger schemes, it’s a good idea to have a supply contract to ensure a reliable supply of wood.

How much will a wood biomass system cost?

A log stove is likely to cost between £500 and £1000, with installation costs probably the same again. Pellet Stoves cost £1,500 to £2,500 plus installation. A log boiler will be roughly £4,000. Together with a water storage tank, flue and installation the total will be about £10,000. Automated pellet boilers are more advanced, and so is the price tag: £6,000 to £8,000 for the boiler; the total perhaps £10,000 to £15,000.

Remember to factor in the ongoing purchase of fuel. Bought in bulk, log fuel should be cheaper than gas, oil or coal. A 15kg bag of pellets will cost £3 to £4, but bulk delivery should be similar to or less than fossil fuel. The Log Pile service (below) lists suppliers around the UK. Also, find out about the support structure in place for the equipment you choose, before going for the cheapest. Will it be easy to get the appliance serviced annually? Are there enough plumbers or engineers with the relevant knowledge?

Which wood biomass fired appliance should I choose?

Before switching to any new heating system it is vital to maximise energy efficiency. Measures such as increasing insulation, lagging pipes and draught-proofing will save money on fuel, and also on equipment - as they’ll allow you to specify a smaller boiler. A combination of wood fuel and solar water heating (for hot water in summer), can give renewably-generated heat all year round.

Open fires are a poor choice, financially and environmentally. Most of the heat goes up the chimney and the rate at which the fire draws in oxygen creates draughts across the room that reduce the benefit from the fire. A simple wood stove is a great improvement; it should need only one-third as much fuel, as the efficiency can reach 70%. Automated pellet stoves are more convenient, and can even have an automatic de-ashing function.

Advanced wood heating systems for larger houses have been common for many years in mainland Europe and the USA, and are as efficient as modern gas boilers - converting well over 80% of the fuel into useful heat.

A ‘batch’ log boiler can be fired up once a day (or less often) and the heat stored in a large water cylinder. Automated pellet boilers make wood fuel almost as convenient as gas. They are more costly, but ease of use is a big plus. For those keen on range cooking there are specially designed wood-fired ranges, with a bigger firebox to accommodate logs. Doing everything from one appliance is not ideal, so the efficiency of these is less than dedicated boilers or stoves, but they would give the satisfaction of a wood-fired sunday roast!

Why burn wood biomass?

Biomass fuels include wood, energy crops such as oilseed rape or miscanthus (‘elephant grass’), animal wastes and other agricultural by-products such as straw and grain husks. When burned, these fuels release only the amount of carbon dioxide (CO2) that they absorbed whilst growing - unlike the carbon in coal, oil and gas, which was absorbed over millions of years but is being released in the space of a few decades. The energy used to harvest, process and transport the fuel does need to be factored in as well. Very little energy is needed to harvest wood, so when used locally it is a very low-carbon option.

Planting trees to absorb carbon dioxide may provide temporary mitigation from climate change, but doesn’t address the fundamental problem. To meet our energy needs in a zero-carbon future we must make sustainable use of trees as fuel, and replant them as we harvest them – creating a continuous carbon cycle. Growing our own fuel also creates jobs and is ideal for strong, local economies.

MICRO HYDRO POWER


CROATIAN CENTER of RENEWABLE ENERGY SOURCES

MICRO HYDRO POWER



Hydro electricity can be one of the cheapest methods of providing off-grid renewable electricity, but it is also very site specific. The best sites are on steep hills, with fast flowing water. One advantage is that on a good site you may not need batteries or an inverter (to step from DC to AC voltage), as the turbine will produce 240 volts AC and can just be turned on when needed.

The capital cost of hydro power schemes is quite high, but if you have a suitable site it can be a good investment. As of Spring 2010, ‘feed-in tariffs’ give a good price for electricity generated - a reasonable size scheme can recoup costs in 5 years or so.

To learn more about this technology, take a look at our blogs
http://solarserdar.blogspot.com/
and
http://solarserdar.wordpress.com/

Related questions


Do I need permission to install a micro hydro system?

If you are planning to remove or abstract more than 20m2 (20,000 litres or approx. 4,400 gallons) of water per day from a watercourse you will need an abstraction licence, even if the water is later put back into the watercourse. This means that virtually all micro hydro projects will require such a license, as even a flow rate of 1 litre per second amounts to 86m2 per day.

The license must be sought from the Environment Agency, who will assess effects on river ecology and flooding, prior to installation. The Environment Agency recommends that you contact them as early as possible as it can take around 3 months to get the license. For further information, consult the Environment Agency's document "Abstracting water - A guide to getting your licence".


It's also worth discussing details with local planning officials, as the powerhouse ans pipework may require planning permission.

If you don't own the land involved you'll need to seek permission from the landowners.

Can I convert an old watermill to generate electricity?

Old watermill sites are not usually good for generating electricity. A large, slow-moving body of water gives a high torque (turning force) and waterwheels make use of this to operate machinery directly. Low rotational speeds makes it difficult to use them for electricity generation; it’s easier to make electricity with a fast flow of water that can be channelled to hit a turbine at high pressure. Waterwheels are also expensive to construct compared to water turbines and need lots of maintenance. However, some 8,000 mills or mill sites are recorded in Britain, and as a small number may be suitable for generating electricity, it may be worth looking into. A hydro turbine installed at Gants Mill in Somerset generates up to 12kW of electricity and feeds into the local grid.

Another example is a waterwheel adapted to generate electricity at Pedley Wood in Cheshire.

The most suitable type of waterwheel for conversion to electricity production is the overshot style, as it has the highest head. It often proves worthwhile to increase the head by raising the headrace and/or lowering the tailrace. Some types of waterwheel can operate at a very low fall of only a few metres – you’d then need large flows of water to get reasonable amounts of power out of them.

Generators operate most efficiently at high speeds. Motors or generators that run at very low rpm (revolutions per minute) are large and expensive - a 1000rpm motor is much bigger than a 1500rpm one. Therefore, it may be more practical to gear up to a faster turbine, or consider installing a micro-hydro turbine instead.

How much will a micro hydro system earn?

The feed-in tariff (FiT) scheme for renewable electricity generation can make micro-hydro a very attractive option. Under this scheme, a generator receives a certain payment (19.9 p/kWh for systems installed in 2010/11) for every unit of electricity generated from micro-hydro power, whether you use it yourself (and save on bills) or sell it to the grid (for another 3 p/kWh).

For a 5 kW hydro scheme, this could work out to annual payments of £5,000 to £10,000, guaranteed for 20 years. However, to be eligible for FiT income, the hydro scheme has to be installed by a professional accredited under, and using turbines registered with, the Microgeneration Certification Scheme.

How much electricity can a micro hydro system produce?

A good hydro site depends on the 'head' of water (the vertical drop) and the flow rate. To estimate the energy in a water source, multiply the flow (in litres per second) by the head (in metres) by 10 (acceleration due to gravity). Halve the result, to account for losses and inefficiencies, to get an idea of potential power generation (in watts).

Flow x Head x 10 x 0.5 = Potential power generation in Watts

As this equation makes clear, a greater head will provide more power. Also, as a high head turbine will spin very quickly, there may be no need for complex gearboxes or belts.

Most micro-hydro schemes are ‘run-of-river’ - they don’t have a reservoir and only take water from the stream when it is available. You usually need a drop of over 10 metres for a scheme to be viable. Highhead ‘Pelton’ turbines are comparatively cheap, easy to install and work well in fluctuating flow. Crossflow turbines are more suitable for lower heads. Other turbines are available; suitability depends on a combination of the available head and flow of water.

HEAT PUMPS by SOLAR SERDAR


RENEWABLE ENERGY CENTER SOLAR SERDAR (CRECSS)

HEAT PUMPS


Heat pumps use the same technology as fridges or air-conditioning units, but instead of taking heat out of the house, they bring heat in from the outside air or from the ground.

A heat pump will use electricity, so as long as grid electricity is generated by fossil-fuel and nuclear power stations it will not be a completely renewable heat source. It is important to make sure a heat pump operates very efficiently if it is to be a better option than gas or oil fired heating. A recent field trial report on heat pumps revealed that heat pumps installed in the UK in recent years often only reach low levels of efficiency, often offering little or no environmental or financial advantage compared to, say, gas heating. However, it seems that the problem is primarily that many systems were badly installed, or put into buildings that aren't suitable. There is evidence from both continental Europe and the UK that heat pumps can reach high levels of performance if specified and installed correctly.

The key thing is to have a well-insulated home, a correctly-sized heat pump and a low-temperature heating system - ideally underfloor heating running on water heated to only 35 degrees C.

Our information sheet gives more advice on how to evaluate the efficiency of a heat pump, how the different types work, and what the costs are likely to be.

Related Questions


What is a heat pump?

You’ll almost certainly have a heat pump in your home already, as they are used to keep fridges cool - basically by ‘pumping’ heat out. Most air conditioning units are also heat pumps. Both of these are generally airsource systems.

A ground source heat pump will usually be the more efficient option for home heating – giving the lowest running costs. Air-source systems are cheaper to install, but their efficiency will drop as air temperatures drop (when you need heat most). Also, heat transfer from air is more difficult than from other sources. Water-source systems can be very efficient, but they’re not common because you need a water source that will not freeze (such as a spring).


Are air-source heat pumps (ASHPs) noisy?

There will be some noise - check technical literature on manufacturers' websites for figures. Worcester Bosch quote 65 decibels (db) for the noise level at 1 metre from their unit. By comparison, normal conversation may be at a noise level of 50db, a busy office about 60db, and a busy street about 70db. The external part of an ASHP is basically the same as an air conditioning unit, but they do vary a lot - so don't judge all ASHPs by the noisiest air conditioner.

Are heat pumps environmentally friendly?

To be environmentally beneficial, the whole heating system must be properly specified and the house very well insulated (to a level above that specified by current UK Building Regulations). You can vastly improve the efficiency of your existing property with simple energy conservation measures - see our ‘Energy Conservation’ section for advice.

The efficiency of a heat pump is given by its coefficient of performance, or COP. A system operating at COP3 will give out 3 units of heat energy for each unit of electricity used. However, you need to bear in mind that most grid electricity is generated from fossil fuels or nuclear power, at efficiencies of only 30 to 40%, so you’ll need a very good COP to outweigh this. If a system has a poor COP you’d be better off with a gas boiler, which would give off less carbon dioxide and make a smaller contribution to climate change. Electricity generation also causes other forms of pollution: sulphur & nitrogen oxides (that cause acid rain), particulates, mining impacts, and nuclear waste.

An Energy Saving Trust field trial of 83 heat pumps in the UK found a wide variance in performance - only a few reached a COP of 3 or more. The average COP for air source heat pumps was 2.1, while the average for ground source systems was 2.3. Many were early installations, and as installers gain experience, performance should improve. To avoid a low COP, ensure that a home is well-insulated, has a low-temperature heating system and good heating controls, and that the ground loop or air-source unit has been adequately sized. See other questions and our information sheet for advice.

You can sign up for a ‘green tariff’, and have your electricity use allocated to renewable sources such as wind or hydro power. This is an excellent way to help promote the growth of the renewable energy industry, but it’s not a green light to use loads of electricity! Doing so will increase overall electricity demand, and until more renewable energy technologies are ready, this will increase the use of fossil fuels and nuclear power.

If you have a stream that would be suitable for a micro-hydro system, then a renewably-powered heat pump could be feasible and beneficial. See our Micro-Hydro information sheet for initial advice on this technology.

A heat pump contains about 2 kilos of refrigerant, usually hydrofluorocarbons (HFCs). These are potent greenhouse gases (about 1600 times more powerful than carbon dioxide) and a leak during or after the system’s life will have a damaging impact. Some suppliers use hydrocarbon refrigerants such as R290 or R600a (propane & isobutane); these will have a much lower impact if accidentally leaked.

Do I need a lot of land space for ground-source heat pump (GSHP)?

Trenches should be at least two metres deep to harness a consistent year-round heat source. Trenches will need 50-80 metres of pipe per kilowatt (kW), or 10 metres of ‘slinky’ coiled pipe per kW, with at least 5 metre distance between trenches with coils. So a typical 8kW heat pump requires around 400m2 of ground area for slinky coils. Note, however, that this will depend on a number of factors, including ground conditions.More info at http://solarserdar.wordpress.com/.

Boreholes need 20-50 metres of pipe per kW, and will usually be 100-150 metres deep. You may need 2-4 pipes per borehole, or more than one borehole. The Pipe diameter should be 20 to 40mm for best performance: large enough to reduce pumping power but small enough to increase flow velocity and cause ‘turbulent flow’ (giving better heat transfer). Bear in mind that installers trying to reduce costs might skimp on the length or bore of pipe, or the depth of the trenches.

What's the difference between an air-source and a ground-source heat pump?

Ground-source heat pumps (GSHPs) draw heat from under the ground using either a borehole or a series of pipes laid a few metres below the surface. This
heat is mainly solar energy that has been absorbed by the ground. The ground below a couple of metres down is protected from extremes of heat or cold and stays at about 10°C all year. This is of course not warm enough in itself - the heat pump ‘boosts’ it to the level needed for heating a home.

Air-source heat pumps (ASHPs) do the opposite of air-conditioning units. Instead of taking heat out of a building, they take heat from the outside air and uses it to heat a house. See our related questions to see which one is right for you.

How efficient are heat pumps?

A heat pump operates most efficiently when the temperature gap between the heat source and the heat demand is minimised. To reach COP4 you must have a very well insulated house - usually a new-build or an extensive renovation. Heat pumps will not be able to heat water to 75°C for standard radiators, so you’ll need a low temperature system. Large radiators can be run on water at about 50°C, whilst underfloor heating can be run at only 35°C. Underfloor heating can be fitted under solid or suspended timber floors, but thick carpets should not be used – they’ll stop the heat coming through.

So that a heat pump can work at maximum efficiency all year round it is usually sized to meet about 90% of the heating demand. This means some form of backup heating is likely to be needed during very cold spells – for example a wood-fired room heater. Heating domestic hot water to 60°C will further diminish efficiency, so an immersion heater is often used - which means more electricity use and higher costs. Solar water heating is a good alternative for hot water - see our solar water heating section for more advice.

High quality heating controls are needed to run the system as efficiently as possible. Weather compensation controls regulate internal heating according to the outside temperature. For example, in cool weather underfloor heating may need water at only 25°C to provide suitable comfort.More info at http://solarserdar.blogspot.com/.

CLEAN ENERGY PRINCIPLES - SOLAR SERDAR


RENEWABLE ENERGY CENTER SOLAR SERDAR





Clean Energy Principles



We have all the tools and resources we need to solve the climate crisis. Here in the U.S., by using our energy more efficiently, utilizing clean, renewable energy sources, upgrading and expanding our energy infrastructure, and transitioning to low carbon fuel sources in our transportation sector, we will not only reduce global warming, but also save American consumers money and create new jobs and business opportunities.

Energy Efficiency
Millions of dollars and enormous amounts of energy are wasted each year simply because our homes and businesses aren’t as energy-efficient as they could be. To make the most out of the energy we currently produce, America needs a national efficiency upgrade. The result will be more comfortable and valuable homes and buildings, lower utility bills, and tens of thousands of new jobs as we retrofit existing buildings to be more efficient and manufacture more American products that use less energy.

Renewable Energy
America’s power sector relies on fossil fuels and emits pollution that endangers the air we breathe, the water we drink, and heats up our atmosphere. We need to accelerate the ramp-up of clean, renewable electricity sources through policies that support increased private and public investment in clean energy technologies. Renewable energy will deliver clean, reliable power to meet America’s needs, reduce carbon pollution and make real progress toward solving the climate crisis.

Energy Infrastructure
The U.S. electricity transmission and distribution system — or “grid” — is in critical need of an upgrade. Investing in a modern transmission infrastructure will enable clean electricity to power American homes and businesses. Smart grids can enable households to sell excess electricity they may produce from their solar panels, providing a new source of revenue. One day, smart grids may interact with our electric-drive vehicles, enabling renewable energy to be stored in the batteries, and deployed when we need it most. Smart meters can inform users of their energy usage, and enable them to take actions to reduce their electricity consumption during peak hours, saving money. Investing in our energy infrastructure can provide many opportunities to create even more innovative ways of making inroads to repowering America with 100 percent clean energy.

Transportation
U.S. passenger vehicles (cars and trucks) consume about 380 million gallons of gasoline per day and contribute 20% of our global warming pollution. The gasoline for these cars is almost entirely refined from petroleum, nearly 60% of which is imported. We can encourage state and local governments to set greenhouse gas emissions reduction targets for the transportation sector, and make investments in public transit and smart development patterns that can reduce our reliance on personal automobiles and imported oil. Smart transportation systems that provide accessible alternatives to personal vehicles will also make our air cleaner to breathe and make our nation safer by reducing our dependence on foreign oil.More info at

Minimize Your Impact, Save Money

You can take steps to help Repower America each and every day. Make your own switch to energy efficient appliances, power generated by renewable energy, and cleaner sources of personal transportation. With all of us working together, we can build a movement to Repower America.

Change a Light Bulb
Replacing one regular light bulb with a compact fluorescent light bulb will save 150 pounds of carbon dioxide a year.

Drive Less
Walk, bike, carpool or take mass transit more often. You’ll save one pound of carbon dioxide for every mile you don’t drive.

Recycle More
You can save 2,400 pounds of carbon dioxide per year by recycling just half of your household waste.

Check Your Tires
Keeping your tires inflated properly can improve gas mileage by more than three percent. Every gallon of gasoline saved keeps 20 pounds of carbon dioxide out of the atmosphere.

Use Less Hot Water
It takes a lot of energy to heat water. Use less hot water by installing a low flow showerhead (350 pounds of CO2 saved per year) and washing your clothes in cold or warm water (500 pounds saved every year).

Avoid Products With a Lot of Packaging
You can save 1,200 pounds of carbon dioxide if you cut down your garbage by 10 percent.

Adjust Your Thermostat
Move your thermostat down just two degrees in winter and up two degrees in summer. You could save about 2,000 pounds of carbon dioxide a year with this simple adjustment.

Plant a Tree
A single tree will absorb one ton of carbon dioxide over its lifetime.

Turn off electronic devices
Simply turning off your television, DVD player, stereo, and computer when you’re not using them will save you thousands of pounds of carbon dioxide a year.

THE SOLUTION for RENEWABLE ENERGY by SOLAR SERDAR (CCRES)



Croatian Center of Renewable Energy Sources (CCRES)

Renewable Energy



The Problem

Today’s U.S. power sector emits large quantities of greenhouse gases and relies heavily on carbon-based fuels with volatile and rising prices. The current system is unsustainable, both economically and environmentally. Electricity generation accounts for approximately one-third of America’s global warming pollution. Scientists urgently warn such pollution must be sharply reduced to avert the most serious consequences of climate change. Meanwhile, viable, non-polluting generation alternatives exist to deliver reliable, cost-effective power to meet America’s needs.

The Solution
Generate 100% of U.S. electricity from truly clean carbon-free sources. Renewable energy generation technologies like solar thermal, photovoltaics, wind, geothermal and biomass have been adding clean, reliable power to the grid for more than a decade. This includes solar and geothermal plants in the southwest, biomass in the northeast and southeast, and wind farms through the Midwest corridor. It is now time to dramatically ramp-up the contribution of renewables to the energy mix. And the circumstances are just right:

Technology maturity: The renewable power technologies featured in the Alliance’s Repower America plan are in the 2nd, 3rd or 4th generation of development and come with the associated reliability and enhancements mature technology offers.
No fuel costs: At a time when fossil fuel prices are volatile and will inevitably rise, shifting to power sources with free and limitless fuel inputs makes sense.
Investor support: During the past few years, clean energy has been among the fastest growing sectors in the venture capital and investment banking worlds: in 2008 global investment in clean energy totaled $155 billion. Even during the global financial crisis, the investment growth in clean energy was 5% over the previous year in 2007. The year before, the increase in investment was a whopping 59%.1
Utility understanding: Virtually every state now has experience in integrating renewable electricity into its energy mix. Twenty-eight states now have renewable energy portfolio standards.
Resource availability: Whether it is solar, wind or geothermal, each of these renewable resource types could on its own theoretically meet all of the nation’s power demands, now and well into the future.
Materials availability: There are no limiting material constraints with any of the renewable generation technologies comprising the Repower America scenarios. Key inputs are steel, concrete and glass. Wind turbine blades also use carbon fiber or fiber glass and PV cells rely on specialized materials, none of which will be limited at the levels and timeframe within the Repower America plan.
Workforce availability: Manufacturing of components and construction of the renewable power plants themselves are skills that can be learned and are easily transferable from other sectors. In Pennsylvania, former steel workers are now building wind turbine components. In Iowa, former appliance manufacturers are doing the same. In California and New Jersey, former construction workers are now installing rooftop solar PV. And clean energy programs are already emerging at colleges and trade schools around the nation.
Growth histories and trajectories: U.S. installed capacities of solar photovoltaic and wind power have been growing rapidly; the U.S. wind energy industry increased the nation’s total wind power generating capacity by 50% in 2008, to over 25,300 MW.2 Solar thermal has rapidly expanded in recent years; and the geothermal heat pump industry has seen double digit growth over the past five years. In 2008, total shipments of geothermal heat pumps surged more than 40 percent.3
The Benefits
Existing, proven renewable power technologies rely on fuels that are free and limitless. They emit no CO2. They eliminate the uncertainty of volatile fossil fuel prices. And, they’re a promising engine of job creation: a $100 billion investment in a clean energy economy over two years would create 2 million new jobs with a significant portion of these jobs helping to revive struggling construction and manufacturing sectors.4

How We Get There
Accelerate the ramp-up of clean, renewable electricity sources through new policies and increased private and public investment in technologies that work. These technologies already exist and have been expanding, but effective policies must be implemented to unleash their potential.

Key Sources of Energy in a Repowered America
Wind Power: Our capacity is growing. Last year, wind power provided 42% of all the new generating capacity added in the U.S. For the fourth consecutive year, wind power was the second-largest new resource added to the U.S. electrical grid. The US is the world leader in wind electricity generation, since the end of 2008 when we passed Germany.5

Solar Thermal Power: Concentrated solar thermal power systems, also known as solar thermal power, covering a parcel of land fewer than 100 miles on one side in the Southwest could theoretically supply 100% of America’s electricity needs.6 A proven technology just beginning to scale up in the U.S., solar thermal power already produces enough electricity for about 100,000 homes. Large-scale projects by eight different companies are underway with major utilities to power 10 times that many homes in the next three years. Industry engineers project that plants put into operation after 2013 – and perhaps sooner – will come equipped with 6-8 hours of energy storage, allowing them to continue to provide power after the sun goes down.

Solar Photovoltaics: Photovoltaic (PV) technology converts sunlight directly into electricity. Solar PV can be mounted on rooftops, integrated into roof tiles, or placed in empty fields, and can produce electricity even on cloudy days. Germany is a great testament to PV generation potential under cloudy skies: Germany’s solar resources (see map below) are similar to those of Alaska’s, one of the U.S.’s least desirable solar regions. Yet, Germany currently has more than three times the installed solar capacity of the entire U.S. due to its supportive policy framework. At the end of 2008, Germany had 5,308 MW in cumulative capacity compared to the U.S. at 1,547 MW.7 With vastly better solar resources in the U.S. and continued innovations and price reductions in solar technologies, the domestic photovoltaic industry has already begun to take off. There are currently thousands of companies developing, producing, installing, and maintaining PV systems in the U.S.

Geothermal Power: The United States is already the world leader in geothermal electricity generation, producing enough electricity from geothermal systems to power approximately 1.5 million homes. Industry experts project that geothermal development can expand to provide 15-30 times as much power over the next few decades due to recent advances in enhanced geothermal systems (EGS) that can harness heat energy stored up to 10km below the surface. According to an MIT study, 100,000 megawatts of electricity could be installed by 2050 with EGS technology that could power over 70 million homes. In October 2009, the Department of Energy awarded up to $338 million in Recovery Act funding for exploration and development of new geothermal fields and research into advanced geothermal technologies. The grants will support 123 projects in 39 states.8 These projects tap into the massive amount of recoverable heat energy in America that is equivalent to about 2,000 years worth of 2005 US electricity consumption.9

Other Renewable Generation: Other renewable generation includes biomass power, which can encompass many sources of carbon-free electricity like agricultural or wood residues and municipal waste. Advanced hydropower technologies are also emerging that harness the energy from waves, currents, and tides.

PRESIDENT OBAMA SAVE JOBS IN SOLAR INDUSTRY






President Obama, Bipartisan Champions in Congress Save Jobs for Thousands in U.S.
Solar Industry



Successful Treasury Section 1603 Program Extended for One Year


WASHINGTON, DC – Solar Energy Industries Association (SEIA®) President and CEO Rhone Resch released the following statement today on President Barack Obama signing tax legislation into law that extends the Department of Treasury Section 1603 program for one year:

“It took a year of tireless effort from the entire solar industry and our champions in Congress to get an extension of the 1603 program. President Obama and our bipartisan champions in the Senate and House recognize that the solar industry is one of the fastest growing industries in our country, and this extension will create tens of thousands of new jobs for Americans.

“This is a great day for America’s solar industry. With an extension of the 1603 program now in place, the solar industry can continue its record growth, creating new career opportunities for Americans in all 50 states in 2011."

The program was created by the American Recovery and Reinvestment Act (Section 1603) to provide commercial solar installations with a cash grant in lieu of the 30 percent solar investment tax credit (ITC). President George W. Bush signed the 8-year ITC into law in 2008, but the economic conditions created by the global recession made it clear that few would be able to utilize the tax credit.

So far, the TGP has helped move forward more than 1,100 solar projects in 42 states and supported $18 billion in investment. The program has been critical in allowing the solar industry to grow by over 100 percent in 2010, create enough new solar capacity to power 200,000 homes and provide work to more than 93,000 Americans.

LETTER OF THANKS FROM SEIA :
-------------------------------------------------------------------------------------

We won, thanks to you.

Željko Serdar,

Just a few short weeks ago when the President announced his agreement with Republican leadership on tax legislation, the situation looked desperate. The critical solar grant program had been part of an earlier tax package, but it was not included in the negotiated compromise.

With your help, we turned that around in 72 hours. You sent thousands of messages and helped us make the case to key members of Congress that the grant program was critical to continuing the growth of solar energy in 2011 and they heard you! Last Friday, the President signed the tax package into law including a one-year extension of the Section 1603 renewable energy grant program.

But what's all this for? How does it help create a clean energy future for our country? This polic creates a critical financing option that supports solar growth in all 50 states.

See for yourself how solar is working for America. Solar energy is springing up all across the country, in places and ways that nobody would have guessed even 3 or 4 years ago. The Solar Generation Road Trip shows how solar is already generating reliable, clean energy and saving customers money today. But now we can reach more communities across the country.

This was a huge win for the solar industry, the economy and the planet. Thanks for making 2010 a great year for solar!

Wishing you a great holiday season,

Scott, Dan, Michael & the rest of the SEIA Government Affairs Team

-----------------------------------------------------------------------------------

We would like to take this opportunity of thanking our partners for their continued patronage and of sending them our best wishes for Christmas and the New Year.

THINKING ABOUT GOING SOLAR ?!


RENEWABLE ENERGY CENTER SOLAR SERDAR


THINKING ABOUT GOING SOLAR ?


Solar energy is the cleanest, most abundant, renewable energy source available. And the U.S. has some of the richest solar resources shining across the nation. Today's technology allows us to capture this power in several ways giving the public and commercial entities flexible ways to employ both the heat and light of the sun.

The greatest challenge the U.S. solar market faces is scaling up production and distribution of solar energy technology to drive the price down to be on par with traditional fossil fuel sources.

Solar energy can be produced on a distributed basis, called distributed generation, with equipment located on rooftops or on ground-mounted fixtures close to where the energy is used. Large-scale concentrating solar power systems can also produce energy at a central power plant.

There are four ways we harness solar energy: photovoltaics (converting light to electricity), heating and cooling systems (solar thermal), concentrating solar power (utility scale), and lighting. Active solar energy systems employ devices that convert the sun's heat or light to another form of energy we use. Passive solar refers to special siting, design or building materials that take advantage of the sun's position and availability to provide direct heating or lighting. Passive solar also considers the need for shading devices to protect buildings from excessive heat from the sun.More info at http://solarserdar.blogspot.com/.

Thinking about going solar?

Putting solar on your home or commercial property is a great way to save on your utility bills, guarantee a fixed energy rate, cut harmful pollution and become more energy independent. It's also more efficient to produce energy near where it is used.

First step is to assess whether your property is a good site for solar. You should have a span of open rooftop space or land that is free of shade for at least 5 hours a day. Rooftops work best if facing south, but your installer can likely set your panels at an angle to capture enough sun from other directions.

Like any home or business property improvement, it's a good idea to get at least three solid proposals from experienced contractors. Check references on past projects and ask about credentials, licenses and membership in trade and business groups. SEIA requires members to sign a code of ethics, pledging to deliver high-quality service and fair and honest rates.More info at http://solarserdar.wordpress.com/.

Find a job in solar or start a business

Besides being a great time to go solar, it's a great time to consider a job in solar. The U.S.solar industry is expanding at a compound annual growth rate of more than 50 percent, so there is a need for qualified employees all along the supply-chain from researchers, materials suppliers and manufacturers to project developers, installersand construction workers, as well as support from financing, legal, and marketing.

You may be able to transfer your skills and experience directly to help a solar energy company expand, get training to transition to a new career in solar. There are a variety of government sponsored and industry training and certification programs to choose from.

Contractors and building companies often extend their service offerings to include solar energy installation drawing on their experience in HVAC, electrical, plumbing, construction and general contacting.More info at www.solar-serdar.com.

The solar industry employs almost 100,000 Americans across all fifty states, and is projected to support over half a million American jobs by 2016. These jobs exist across many sectors of the economy—from manufacturing and engineering, to construction and sales, and across supporting industries.

Unlike other energy sources, solar resources exist throughout the nation, meaning that solar energy can strengthen the economy of every state and region with solid wages and sustainable careers.

Solar energy is the cleanest, most abundant, renewable energy source available. And the U.S. has some of the world's richest solar resources. Solar workers help to capture this massive, domestic energy source to power our homes, businesses and vehicles, while strengthening our national security by reducing our dependence on fossil fuels.
More info at solarserdar@gmail.com.

Solar is an Emerging Economic Engine

A robust solar industry in the U.S. is an economic engine that will help relieve a struggling American economy. With aggressive and effective national policy, solar power will create tens of thousands of jobs across the country and will spur billions of dollars in economic growth and tax revenue. Consider the growth of solar in 2007:

New solar installations nationwide increased by more than 40 percent from 2006 to 2007.
Expansions of solar energy companies resulted in 6,000 new jobs, 265 megawatts of energy and more than $2 billion of investment in the U.S. economy by Wall Street firms such as JP Morgan, Chase and Goldman Sachs.
The first utility-scale solar power plant in the U.S. in 18 years went online.

The National Renewable Energy Laboratory (NREL) estimates that an additional thirty gigawatts of solar energy will be deployed as a result of the recent eight year extension of the solar investme. This is enough energy to power more than five million homes! NREL also estimates that the solar market would continue to drive increased deployment even after the tax credits expire.

An expanding solar market creates thousands of new jobs - jobs like electricians, construction workers, plumbers, line workers, roofers, engineers and high-paying manufacturing positions - for a struggling economy. More info at http://solarserdar.blogspot.com/.

Solar Leads the Way in Stabilizing America's Energy Security

Energy security is increasingly finding its way into the national consciousness. Whether in terms of national security or our ability to respond to domestic challenges such as natural disasters, energy is one of the most critical issues facing the U.S. Solar provides crucial energy supplies vital to the function of homes, businesses and the entire economy.

The hurricanes in the fall of 2005 were a stark reminder of the vulnerability of our domestic supplies of oil and natural gas to severe weather and environmental factors. Not only does solar energy provide reliable access to energy where it is used, but it can supplement energy needs in blackouts and disaster recovery for electricity, water pumping and hot water.

With the cost of oil rising to more than $130 per barrel, a gallon of gasoline to more than $4 at the pump and skyrocketing electric bills, Americans are feeling the squeeze. Complicating matters, most of America's energy supply arrives from politically volatile regions of the world. Rapidly growing economies, such as China and India, are staking larger and larger claims to dwindling global energy resources. According to the Energy Information Agency, two-thirds of the petroleum and 20 percent of the natural gas consumed in the U.S. is imported from other countries, and U.S. production of both is dropping while consumption continues to rise.

A fully-developed U.S. solar market will decrease our overdependence on foreign sources of oil and natural gas and meet long term demands for domestically produced clean energy. The U.S. must make a long term investment in a diverse, clean, and renewable energy portfolio - with solar in the lead - if it is to have a secure energy future.

Harnessing the Power of the Sun to Confront Global Climate Change

As global climate change impacts the way the U.S. addresses environmental policy, conducts business and harnesses energy, the solar energy industry is leading the way with a renewable energy source that creates economic growth and reduces carbon emissions. Solar is an pollution-free source of electricity and hot water that can be immediately deployed to reduce the nation's growing carbon footprint.

As the federal government considers climate change legislation, Congress should create carbon output-based market rules that encourage carbon-free technologies and allow energy sources such as solar to be rewarded for producing.

SOLAR TECHNOLOGY & PRODUCTS by SOLAR SERDAR


RENEWABLE ENERGY CENTER SOLAR SERDAR (CRECSS)


SOLAR TECHNOLOGY & PRODUCTS


Solar Electric (Photovoltaic)

Photovoltaic (PV) devices generate electricity directly from sunlight via an electronic process that occurs naturally in certain types of material, called semiconductors. Electrons in these materials are freed by solar energy and can be induced to travel through an electrical circuit, powering electrical devices or sending electricity to the grid.

PV devices can be used to power anything from small electronics such as calculators and road signs up to homes and large commercial businesses.

History
The PV effect was observed as early as 1890 by Henri Becquerel, and was the subject of scientific inquiry through the early twentieth century. In 1954, Bell Labs in the U.S. introduced the first solar PV device that produced a useable amount of electricity, and by 1958, solar cells were being used in a variety of small-scale scientific and commercial applications.

The energy crisis of the 1970s saw the beginning of major interest in using solar cells to produce electricity in homes and businesses, but prohibitive prices (nearly 30 times higher than the current price) made large-scale applications impractical.

Industry developments and research in the following years made PV devices more feasible and a cycle of increasing production and decreasing costs began which continues even today.

Present Status
The cost of PV has dropped dramatically as the industry has scaled up manufacturing and incrementally improved the technology with new materials. Installation costs have come down too with more expereinced and trained installers. However, the U.S. still remains behind other nations that have stronger national policies to shift energy use from fossil fuels to solar. Globally, the U.S. is the fourth largest market for PV installations behind world leaders Germany, Japan and Spain.

Most modern solar cells are made from either crystalline silicon or thin-film semiconductor material. Silicon cells are more efficient at converting sunlight to electricity, but generally have higher manufacturing costs. Thin-film materials typically have lower efficiencies, but are simpler and less costly to manufacture. A specialized category of solar cells - called multi-junction or tandem cells - are used in applications requiring very low weight and very high efficiencies, such as satellites and military applications.More info at http://solarserdar.blogspot.com/.

Solar Thermal (Heating and Cooling)

Solar heating harnesses the power of the sun to provide solar thermal energy for solar hot water, solar space heating and cooling and solar pool heaters.

Solar Water Heating

Most solar water heating systems have two parts, a solar collector and a storage tank. The solar collector gathers the sun’s energy, transforms it into heat then transfers the heat to water. The heated water is then stored in the storage tank for later use, with a conventional system providing additional heating as necessary. Solar water heating systems can be either active (relying on electric pumps to circulate water) or passive (relying on gravity and the tendency for water to naturally circulate when heated), but the most common type for use in commercial and residential buildings is active.

Solar Space Heating and Cooling

Active solar space heating systems collect and absorb solar energy and use electric fans or pumps to transfer and distribute the heat. These systems also contain an energy-storage system to provide heat at night or when the sun is not shining.

Passive solar space heating capitalizes on warmth through the sun through design features as well as materials in the walls or floors that absorb heat during the day and release that heat at night.

Perhaps the most interesting new solar thermal technology is the absorption chiller – a closed-loop system that converts solar-heated water into air conditioning. Water heated by the sun through flat-panel collectors or evacuated tubes is subjected to a low-pressure loop with lithium bromide, a phase-change catalysts, which causes the water to reach a cool 44 degrees F. This cooled water runs through copper piping; forced air passing over the coils produces air conditioning.

Solar Pool Heating

Solar pool heating systems use the existing pool filtration system to pump the water through a solar collector and the collected heat is transferred directly to the pool water. Solar pool heating collectors typically operate at a slightly warmer temperature than the surrounding air and normally use unglazed, low-temperature collectors made from polymers.More info at http://solarserdar.wordpress.com/.

Concentrating Solar Power (CSP)

Concentrating solar power (CSP) plants are utility-scale generators that produce electricity by using mirrors or lenses to efficiently concentrate the sun's energy. CSP technologies include parabolic trough systems, power towers, compact linear Fresnel and dish systems which concentrate the thermal energy of the sun to drive a conventional steam turbine.

Parabolic trough systems use parabolic curved, trough shaped reflectors to focus the sun's energy onto a receiver pipe running at the focus of the reflector. Because of their parabolic shape, troughs can focus the sun at 30 to 60 times its normal intensity on the receiver pipe. The concentrated energy heats a heat transfer fluid in the pipe which is then used to generate steam to power a turbine which drives an electric generator.

Power tower systems use a field of computer-controlled flat mirrors (called Heliostats) to focus solar heat on a central collector tower. The high energy at this point can then be used to heat water to produce steam (and run a central generator) or it can be transferred to a heat transfer material (typically liquid sodium) which can then store the heat for later use.

The Compact Linear Fresnel Reflectors use flat reflectors moving on a single axis while using a Fresnel lens to concentrate the solar thermal energy into collectors. The flat mirrors used in this system allow for a greater density of reflectors in the array, increasing the efficiency of land use.

Dish systems use a large concave dish to track the sun and focus the energy onto a high-efficiency power conversion unit, which generates electricity directly. Dish systems typically produce upwards of 25KW.More info at www.solar-serdar.com.

Passive Solar

Architects and builders use special siting, design and materials to absorb and distribute the sun's heat and take advantage of sunlight to brighten interior spaces. Passive solar also refers to positioning shading devices to protect buildings from excessive heat. Passive solar does not have mechanical or special equipment like active solar. Instead, design is adapted to the local climate.

There are several ways to use passive solar to achieve direct gain, indirect gain, and insolated gain. Elements used are: absorber material (dark tile); thermal mass that retains heat during the day, then releases it during cooler evening and nights (trombe wall); aperture (south-facing glazed windows); distribution (allows air flow); and control (overhanging roof or deciduous trees to protect from heavy sun in summer, allowing more light in winter when sun is lower and leaves have fallen).

Passive lighting is another important way to reduce the need for electricity and cut costs. North-facing clerestory windows or a sawtooth roof along with south-facing windows add natural light. Flexible light tubes or skylights allow one to brighten interior spaces with limited or no windows.More info at solarserdar@gmail.com.

Solar Ovens

Solar ovens are a low-tech, low-cost option to heating and cooking food. Similar to a crock pot, a solar oven is essentially a well-insulated portable box that captures and holds the sun's heat. There are a number of commercially available models and many do-it-yourself designs.

Solar ovens, once a quaint idea for an elementary science project, are making a comeback as a staple for emergency preparedness supplies and as an affordable convenience for low-income people in developing countries.More info at http://solarserdar.blogspot.com/.

Emerging Technology

Research and development by companies and research labs are continually discovering new techniques and materials that improve efficiencies and cut the cost of capturing solar energy. The industry seeks to commercialize the most promising technology to improve delivery of solar power generation for homes, business and government. Examples include applying different materials for thin-film PV applications, solar cooling systems, incorporating PV into building materials for roofing, windows and even painted surfaces.

Other areas being aggressively pursued are storage systems (thermal and electrical); solar hybrid lighting; improved manufacturing techniques; nanotechnology; low-cost semiconductor alternatives to polysilicon; and improving concentrating solar power systems.More info at http://solarserdar.wordpress.com/.

CROATIAN CENTER of RENEWABLE ENERGY SOURCES ( CCRES )


Due to its regional dominance, Saudi Arabia can play a vital role in the proliferation of solar energy in the entire Middle East. The Kingdom needs to urgently move forward with its renewable energy plans and start the production of solar energy on a large-scale. The current focus is on increasing levels of efficiency, reducing subsidy and slashing government expenditure and on doing things that truly add value. 
Vision 2030 target suggests that the country will grow its renewable energy capacity in increments, taking advantage of future cost declines and efficiency improvements, while also leaving the door open for emerging technologies. Under the new leadership of King Salman, the country is making a concerted effort to develop its renewable energy sector. The reorganization of stakeholders and decision makers on energy policy and renewables, under one umbrella, should accelerate KSA’s renewable energy program. The government restructuring in May 2016 placed necessary administrative functions under the newly-created super-ministry, the Ministry of Energy, Industry, and Mineral Resources which will eventually pave the way for implementation of solar projects.
However, there are several critical areas which Saudi Arabia should tackle for a smooth transition to renewables-focused energy mix. Saudi Arabia should take a consultative approach on its renewable energy policy framework by leaning on capable, credible industry partners to share their expertise which will help the country avoid the steep learning curve that other markets have faced. Lenders and financiers are an integral part of any industry, and they should be properly informed about green financing. It will be particularly important for banks and lenders based in the Kingdom to better understand the solar energy industry, ensuring that they’re comfortable with providing competitive financing for the program.
It is also essential to adapt solar energy systems to meet specific energy-intensive applications. Saudi Arabia could provide long-term solar energy targets for certain, energy-intensive industrial sectors such as cement, steel and petrochemicals.
Lastly, a well-trained and performing workforce is crucial for the development of solar market. Saudi Arabia needs to invest wisely in technical education to overcome the skills mismatch between schools and the labour market and ensure the supply of rightly-trained human resources to the solar industry.
