We require different sources of energy to live and work. They include wind, solar, geothermal, and biomass sources. In addition to being the primary source of electricity they can also be used to heat and transport. These energy sources produce greenhouse gases when burned to create electricity. This leads to the need for more green energy sources.

Fossil fuels are the most popular type of energy. They include oil, coal and natural gas. They formed millions of years ago when animals and plants of the past died and were buried under layers of sedimentary rock. Then, under the right conditions, they gradually transformed into carbon-rich compounds that, when burned produce energy. These fossil fuels are non-renewable since they will exhaust in our lifetimes or even in a number of lifetimes.

Renewable energy sources however are continuously replenished. The sun is the most important source of renewable energy, since it supplies light and heat. We use it to power our homes business, cars, and homes. Wind is another renewable energy source that generates electricity by spinning turbines. We have used it since humans first discovered how to harvest the wind for millennia. We employ biological processes to create the ethanol (a alcohol-like substance that is clear and transparent which can be used as fuel) from waste and crops.

In the list of sources hydropower is the most significant renewable energy source in the United States, though wind and biofuels are likely to be the next to take over. Hydropower relies on nature’s water cycle to harness the power of Related Site flowing water, which is used in turn to generate electricity.
