Diverse energy sources provide us with the energy we need to live and work. They include wind, solar geothermal, biomass, and geothermal sources. In addition to being a major source of electricity, these sources can also be used to transportation and heating. These energy sources emit greenhouse gases when used to generate electricity. This is why there is a need for more environmentally sustainable energy sources.
Fossil fuels are the most common 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 https://leonardogiombini.it/2018/06/02/leonardo-giombini-e-le-energie-rinnovabili/ were buried under layers of sedimentary rock. Under the right conditions they were slowly transformed into carbon-rich materials which, when burned, produce energy. These fossil fuels are non-renewable since they will be exhausted within our lifetimes or in many lifetimes.
Renewable energy sources are replenished continuously. The primary renewable energy source is sunlight, which gives light and heat. We use it to power our homes and businesses as well as to drive our cars. Wind is a different renewable energy source that generates electricity through spinning turbines. We have been using it since we first discovered how to harvest the wind for millennia. In the end, we employ biochemical processes to create the ethanol (a clear alcohol that can be used to create fuel) from waste and crop residues.
Hydropower is the most important renewable energy source in America, however wind and biofuels will soon overtake it. Hydropower is based on nature’s water cycle to harness the power of fast-flowing water, which is used to generate electricity.
