We require different sources of energy to work and this post live. They include wind, solar and geothermal as well as biomass sources. These sources are not just a major source for electricity, but they can also be used to heat or transport. These energy sources produce greenhouse gases when they are burned to create electricity. This is why there is a need for more sustainable energy sources.

The most widely used type of energy is fossil fuels, which include coal, oil, and natural gas. They were created thousands of years ago when prehistoric animals and plants died and were buried beneath layers of sedimentary rocks. Under the right conditions the fossil fuels slowly transformed into carbon-rich materials which, when burned produce energy. These fossil fuels are not renewable since they will exhaust in our lifetimes or in many lifetimes.

Renewable energy sources are continuously replenished. The sun is the most important source of renewable energy since it supplies heat and light. We use it for our homes vehicles, businesses, and homes. Wind is an energy source that is renewable and generates electricity by spinning turbines. We have been using it since the first discovered how to harvest the wind for millennia. In addition, we employ biological processes to make ethanol (a clear alcohol that can be used as fuel) from waste and crops.

Among these sources hydropower is the most significant renewable energy source in the United States, though wind and biofuels are expected to take the lead soon. Hydropower relies on nature’s cyclic water cycle to harness the power of fast-flowing water, which is then used in turn to produce electricity.
