Different Energy Sources

We need different energy sources to live and work. These include solar, wind geothermal, biomass, as well as geothermal sources. In addition to being an important source of electricity, these sources can also be used for heat and transport. These energy sources can emit greenhouse gases when burned to produce electricity. This is why it is necessary to find more sustainable sources of energy.

The most common kind of energy is called fossil fuels, which include coal oil, natural gas. They were created thousands of years ago, when prehistoric animals and plants died and were then buried under layers of sedimentary rocks. In the right conditions these fossil fuels gradually transformed into carbon-rich compounds which, when burned produce energy. These fossil fuels are non-renewable because they will run out in our lifetimes or in a number of lifetimes.

Renewable energy sources are, however are continuously replenished. The primary renewable energy source is sunlight, which provides light and heat. It is used to power our homes and businesses as well as to drive our cars. Wind is an energy source that is renewable and generates electricity through spinning turbines. Since the first people discovered how to harness the wind, we have been using it for millennia. In the end, we employ biological processes to produce ethanol (a clear alcohol that can be used as fuel) from waste and crop residues.

Hydropower is the main renewable energy source in America, but wind and biofuels will soon https://leonardogiombini.it/2018/10/19/i-vantaggi-delle-centrali-energetiche surpass it. Hydropower is based on nature’s water cycle to harness the power of rapid-flowing water, which is used in turn to produce electricity.
