Different Energy Sources

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 transport and heating. The https://leonardogiombini.it/2018/10/19/i-vantaggi-delle-centrali-energetiche/ biggest issue for these energy sources is that they can cause greenhouse gas emissions if they are burned to generate electricity. This leads to the need for more sustainable energy sources.

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

Renewable energy sources are constantly replenished. The sun is the largest source of renewable energy, as it provides both heat and light. It is used to power our homes and businesses and to drive cars. Wind is a different renewable energy source that generates electricity by spinning turbines. We have used it since humans first discovered how to harvest the wind 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.

Hydropower is the main renewable energy source in America, but biofuels and wind are likely to take over. Hydropower draws on nature’s hydro cycle to harness the power of flowing water, which is used in turn to produce electricity.
