Different energy sources supply us with the energy we require to live and work. These include solar, wind and geothermal as well as biomass sources. In addition to being an important source of electricity, these sources can also be used for transportation and heating. These energy sources emit greenhouse gases when they are burned to create electricity. This leads to the need for more green energy sources.
Fossil fuels are the most common type of energy. They include oil, coal, and natural gas. They began to form millions of years ago when animals and plants of the past died and were covered by layers of sedimentary rock. Then, under the appropriate conditions, they gradually transformed into carbon-rich compounds that, when burned produce energy. These fossil fuels are not renewable since they will be exhausted in our lifetimes, or in many lifetimes.
Renewable energy sources are constantly replenished. The primary renewable energy source is sunlight, which supplies warmth and light. We use it to power our homes, businesses, and cars. Wind is renewable energy source that generates electricity through spinning turbines. Since the first time people realized how to harness the wind we have been utilizing it for millennia. In the end, we employ biological processes to produce the ethanol (a clear alcohol that can be used to create fuel) from waste and crop residues.
Among these sources hydropower is the biggest renewable energy source in the United States, though wind and biofuels are likely to become the dominant source in the near future. Hydropower is based on nature’s water cycle to harness the power of flowing water, which is then used for electricity generation.
