Different energy sources supply us with the energy we require to live and work. Geothermal, solar, wind and biomass are some of the sources. These sources aren’t only major sources of electricity, but can also be used to heat and transport. The biggest issue with these sources of energy is that they may cause greenhouse gas emissions when burned to produce electricity. This results in the need for more green energy sources.
The most common type of energy is the fossil fuels, which include coal oil, natural gas. They began to form millions of years ago when prehistoric plants and animals passed away and were then buried beneath layers of sedimentary rock. In the right conditions they were gradually transformed into carbon-rich compounds which, when burned generate energy. The fossil fuels cannot be renewable, as they’ll end up being depleted in our lifetimes or in a variety of lives.
Renewable energy sources however, are continually replenished. The primary renewable energy source is sunlight, which provides heat and light. We use it to power our homes and businesses as well as to drive our vehicles. Wind is a renewable energy source that generates electricity through spinning turbines. We have used it since humans first discovered how to harvest the wind for millennia. We use biological processes produce ethanol (a alcohol-like substance that is clear and transparent that can be used for fuel) from food waste and crops.
Hydropower is by far the most important renewable energy source in the United States, but biofuels and wind are likely to surpass it. Hydropower utilizes the natural water cycle to harness water’s swift flow, which produces electricity.
