Different Energy Sources

Diverse energy sources provide us with the power we need to live and work. They include wind, solar geothermal, biomass, as well as geothermal sources. These sources are not only an important source of electricity, but also can be used to heat or transport. These energy sources emit greenhouse gases when burned to create electricity. This leads to the need for more environmentally sustainable energy sources.

The most common https://leonardogiombini.it/2019/01/24/da-costruttore-le-biomasse-come-fondazioni/ kind of energy is called fossil fuels, comprised of coal, oil, and natural gas. They formed millions of years ago when prehistoric animals and plants died and were buried under layers of sedimentary rock. In the right conditions the fossil fuels gradually transformed into carbon-rich substances that, when burned create energy. These fossil fuels won’t be renewable because they will become depleted by the time we reach our age or over the course of many lifetimes.

Renewable energy sources are constantly replenished. The primary renewable energy source is sunlight, which provides light and heat. It is used to power our homes and businesses as well to drive vehicles. Wind is another renewable energy source, which generates electricity through spinning turbines. Since the first time people realized how to harness the wind in the past, we have been using it for millennia. In the end, we employ biological processes to create alcohol (a clear alcohol that can be used as fuel) from crops and waste.

Of all these sources hydropower is the biggest renewable energy source in the United States, though wind and biofuels are predicted to take the lead soon. Hydropower makes use of the natural water cycle to harness the water’s rapid flow, which can be used to produce electricity.
