We require a variety of energy sources to live and work. Solar, wind, geothermal and biomass are among the sources. In addition to being the primary source of electricity, these sources can also be used for transport and heating. The main challenge https://leonardogiombini.it/2019/01/24/da-costruttore-le-biomasse-come-fondazioni/ for these energy sources is that they could cause greenhouse gas emissions when used to produce electricity. This leads to the need for renewable energy sources that are more sustainable.

The most common type of energy is the fossil fuels, which include coal, oil, and natural gas. They were formed thousands of years ago when prehistoric animals and plants died and were buried under layers of sedimentary rocks. Under the right conditions these fossil fuels slowly transformed into carbon-rich materials that, when burnt create energy. These fossil fuels won’t be renewable since they will be depleted in our lifetimes or over the course of many lifetimes.

Renewable energy sources however are constantly replenished. The sun is the primary source of renewable energy, because it is a source of warmth and light. We utilize it for our homes as well as for businesses and automobiles. Wind is a different renewable energy source, which produces electricity by spinning turbines. Since the first time people realized how to harness wind, we have been using it for millennia. Finally, we use biological processes to create alcohol (a clear alcohol that can be used to fuel) from waste and crops.

Hydropower is the most important renewable energy source in America, however biofuels and wind will soon surpass it. Hydropower is a natural cycle to harness the power of water’s rapid flow, which in turn is used to generate electricity.
