"Is solar power better than fossil fuels?"
The sun’s energy is so powerful that in just 1 hour the amount of energy that falls on the earth equals the amount used by the world’s population in a whole year.
Most of the sun’s energy transforms to processes such as heat and photosynthesis, which are the driving factors behind our weather and biological systems. But it can also be captured and converted into electricity.
Solio has been designed to harness the sun’s energy, shortening the process of transforming it into electricity by using photovoltaic cells (PVs). PVs convert sunlight into electricity that can be used immediately. The process is clean, fast, noiseless, and—thanks to Solio—easily portable. Here’s how it works. Light from the sun hits the solar cells, exciting electrons within the cell. Some of them break free, and are channeled through a conductive metal strip to create an electric current. This current can either be stored in a battery or used directly in the form of electricity. The stronger the sunlight and the more rays that hit the cell, the more electricity is generated.

Now consider fossil fuels. These are formed by utilizing solar energy that has been stored in plants that grew millions of years ago.
After these plants have been buried and compressed under tons of earth, they are transformed into oil. This oil is then extracted and refined, using heavy machinery that pollutes the air. The oil must then be delivered to its destination, creating a need for more polluting machinery.
Ultimately, the burning of this fuel for power has a negative impact on the delicate climatic and environmental balance of our world.
The fossil fuel process takes a long time, and will eventually run out. But as long as the sun burns, we will have the cleaner and more portable option of PVs.
