Solar vs Fossil Fuels
The yearly energy demand for the entire world is about 400 quadrillion BTUs (British Thermal Units) and fossil fuels supply nearly 88%, or 350 quadrillion BTUs, of it. Fossil fuels are the remains of plants and animals that have decomposed while buried deep within the earth over millions of years. Fossil fuels include coal, oil, and natural gas.
Fossil fuels, along with the existence of nearly all life on earth, wouldn't exist without solar energy. Solar power, which comes directly from sunlight, is a renewable energy. There is more than enough solar energy to supply the entire world's energy needs for billions of years and solar cells (electrical devices that can convert sunlight directly into electricity) can help make it happen.
