Different energy sources provide us with the energy we require to live and work. These include solar, wind, geothermal, and biomass sources. In addition to being the primary source of electricity, these sources can also be used for transport and heat. These energy sources can emit greenhouse gases when used to generate electricity. This results in the need for more green energy sources.
The most commonly used type of energy is the fossil fuels, made up of coal, oil, and natural gas. They were formed thousands of years ago when prehistoric animals and plants died and were then buried under layers of sedimentary rocks. Then, under the proper conditions, they gradually transformed into carbon-rich compounds which, when burned, generate energy. The fossil fuels cannot be renewable since they will become depleted by the time we reach our age, or in many lifetimes.
Renewable energy sources are replenished continuously. The sun is the most important source of renewable energy because it is a source of heat and light. We use it find more information to power our homes and businesses as well to drive our vehicles. Wind is an energy source renewable that produces electricity by spinning turbines. We have been using it since the first began to harness the wind for millennia. Finally, we use biological processes to make an ethanol (a clear alcohol that can be used to create fuel) from waste and crops.
As a result hydropower is by far the most important renewable energy source in the United States, though wind and biofuels are predicted to take the lead soon. Hydropower draws on nature’s hydro cycle to harness the power of fast-flowing water, which is used in turn to generate electricity.
