We require different sources of energy to live and work. Geothermal, solar, wind and biomass are some of the sources. In addition to being an important source of electricity they are also used for transport and heat. They can also emit greenhouse gases when they are used to generate electricity. This results in the need for more green energy sources.

The most commonly used kind of energy is fossil fuels, comprised of coal oil, natural gas. They began to form millions and millions of years ago when animals and plants of the past died and were buried under layers of sedimentary rock. In the appropriate conditions, they slowly transformed into carbon-rich substances which, when burnt, generate energy. These fossil fuels are not renewable because they will run out in our lifetimes, or in many lifetimes.

Renewable energy sources, on the other hand are constantly replenished. The sun is the largest source of renewable energy, as it provides both light and heat. We use it to power our homes and businesses as well to drive our vehicles. Wind is an energy source that is renewable and produces electricity by spinning https://leonardogiombini.it/2020/04/18/lesperienza-consolidata-nelluso-della-data-room-aree-gestionali-tecniche-nellinfrastruttura-civile/ turbines. We have been using it since the first discovered how to harvest the wind for millennia. We utilize biological processes to produce an ethanol (a clear, alcohol-like substance that can be used to make fuel) from crops and waste.

Of all these sources, hydropower is the largest renewable energy source in the United States, though wind and biofuels are expected take the lead soon. Hydropower utilizes the natural water cycle to harness the power of water’s rapid flow, which in turn is used to produce electricity.
