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

Fossil fuels are the most popular form of energy. They include oil, coal, and natural gas. They were created thousands of years ago when prehistoric animals and plants passed https://leonardogiombini.it/2020/09/13/esperienza-consolidata-dalla-sala-riunioni-come-conoscere-le-strategie-di-gestione/ away and were buried under layers of sedimentary rocks. In the right conditions, they slowly transformed into carbon-rich substances which, when burned create energy. They are not renewable as they will run out in our lifetimes, or in many lives.

Renewable energy sources are, however are constantly replenished. The most important renewable energy source is sunlight, which supplies light and heat. It is used for our homes as well as for businesses and automobiles. Wind is an energy source that is renewable and generates electricity by spinning turbines. Since the first time people realized how to harness wind in the past, we have been using it for millennia. We use biological processes create ethanol (a clear, alcohol-like substance that can be used for fuel) from the waste of crops and other materials.

As a result hydropower is the most significant renewable energy source in the United States, though wind and biofuels are likely to become the leading source of energy in the near future. Hydropower utilizes the natural water cycle to harness water’s rapid flow, which is used to produce electricity.
