Different energy sources provide us with the power we require to live and work. Geothermal, solar, wind and biomass are just a few of the sources. These sources are not just a major source for electricity, but also can be used to heat or transport. These energy sources can emit greenhouse gases when burned to produce electricity. This creates a need for more environmentally sustainable energy sources.
Fossil fuels are the most common type of energy. They include oil, coal and natural gas. They were created thousands of years ago when prehistoric animals and plants passed away and were buried under layers of sedimentary rocks. After that, under the proper conditions, they gradually transformed into carbon-rich compounds that, when burned produce energy. They are not renewable since they will be exhausted in our lifetimes or even in many lifetimes.
Renewable energy sources On the other hand are constantly replenished. The sun is the largest source of renewable energy, because it is a source of light and heat. It is used to power our homes and businesses, as well as to drive our vehicles. Wind is a renewable energy source that produces electricity by spinning turbines. We have been using it since we first began to harness the wind for millennia. We employ biological processes to produce ethanol (a clear, alcohol-like substance that can be used for fuel) from food waste and crops.
Among these sources hydropower is by far the most important renewable energy source in the United States, though wind and biofuels are expected be the next to take over. Hydropower utilizes the natural water cycle to harness the water’s rapid flow, which produces electricity.
