Different Energy Sources

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

The most common kind of energy is fossil fuels, which consist of coal oil, natural gas. They were formed millions of year ago when prehistoric animals and plants died and were buried under layers of sedimentary rocks. In the right conditions, they slowly transformed into carbon-rich substances that, when ignited produce energy. These fossil https://leonardogiombini.it/2018/06/02/leonardo-giombini-e-le-energie-rinnovabili/ fuels are not renewable because they will run out in our lifetimes or in a number of lifetimes.

Renewable energy sources however, are continually replenished. The sun is the most important source of renewable energy since it provides warmth and light. We use it to power our homes and businesses as well as to drive vehicles. Wind is an energy source renewable that produces electricity through spinning turbines. Since the first time people realized how to harness wind in the past, we have been using it for millennia. In addition, we employ biological processes to produce an ethanol (a clear alcohol that can be used to create fuel) from waste and crop residues.

In the list of sources, hydropower is the largest renewable energy source in the United States, though wind and biofuels are predicted to be the next to take over. Hydropower is a natural cycle to harness the power of water’s rapid flow, which produces electricity.
