We require different sources of energy to work and live. Solar, wind, geothermal and biomass are some of the sources. In addition to being a major source of electricity, these sources are also used for transportation and heating. These energy sources emit greenhouse gases when burned to create electricity. This results in the need for more environmentally sustainable energy sources.
Fossil fuels are the most widely used type of energy. They include oil, coal and natural gas. They began to form millions of years ago when animals and plants of the past died and were covered by layers of sedimentary rock. Under the right conditions they were gradually transformed into carbon-rich compounds that, when burned create energy. They are not renewable since they will be exhausted in https://leonardogiombini.it/ our lifetimes, or in many lives.
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 as to drive vehicles. Wind is another renewable energy source, which produces electricity by spinning turbines. We have been using it since people first began to harness the wind for millennia. We use biological processes to create ethanol (a alcohol-like substance that is clear and transparent that can be used as fuel) from waste and crops.
Hydropower is the most important renewable energy source in the United States, but biofuels and wind are likely to take over. Hydropower utilizes the natural water cycle to harness the water’s rapid flow, which can be used to produce electricity.
