Different energy sources provide us with the power we need to live and work. Geothermal, solar, wind and biomass are a few of the sources. These sources are not only the primary source of electricity, but can also be used to heat and transport. These energy sources can emit greenhouse gases when burned to produce electricity. This leads to the need for more green energy sources.
The most popular type of energy is fossil fuels, which consist of coal oil, natural gas. They were formed millions of year ago when prehistoric animals and plants passed away and were buried under layers of sedimentary rocks. After that, under the right conditions, they slowly transformed into carbon-rich substances which, when burnt create energy. The fossil fuels cannot be renewable, as they’ll run dry in our lifetimes or in a variety of years.
Renewable energy sources are replenished continuously. The sun is the largest source of renewable energy, as it provides both heat and light. We use it 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. We employ biological processes to create the ethanol (a alcohol-like substance that is clear and transparent that can be used to make 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 expected be the next to take over. Hydropower uses the natural water cycle to harness the power of water’s rapid flow, which produces electricity.
