Different energy sources supply us with the power we require to live and work. Geothermal, solar, wind and biomass are some of the sources. In addition to being a major source of electricity, these sources are also used for transport and heat. The major issue with these energy sources is that they could cause greenhouse gas emissions when they are burned to produce electricity. This leads to the need for more sustainable energy https://leonardogiombini.it/2018/06/02/leonardo-giombini-e-le-energie-rinnovabili/ sources.
Fossil fuels are the most well-known type of energy. They include coal, oil and natural gas. They began to form millions and millions of years ago when animals and plants of the past died and were buried by layers of sedimentary rock. If the conditions were right, these fossil fuels were slowly transformed into carbon-rich materials which, when ignited produce energy. These fossil fuels cannot be recycled since they will be exhausted in our lifetimes or in many lives.
Renewable energy sources are replenished regularly. The most important renewable energy source is sunlight, which supplies light and heat. We use it for our homes vehicles, businesses, and homes. Wind is a different renewable energy source, which generates electricity through spinning turbines. Since the first time people realized how to harness wind we have been utilizing it for millennia. We utilize biological processes to produce alcohol (a clear, alcohol-like substance which can be used as fuel) from waste and crops.
Of all these sources hydropower is by far the most important renewable energy source in the United States, though wind and biofuels are expected be the next to take over. Hydropower utilizes the natural water cycle to harness the water’s rapid flow, which in turn can be used to produce electricity.
