Diverse energy sources provide us with the power we require to live and work. Geothermal, solar, wind and biomass are just a few of the sources. These sources aren’t only a major source for electricity, but also can be used to heat or transport. The biggest issue for these energy sources is that they could cause greenhouse gas emissions when used to produce electricity. This creates the need for renewable energy sources that are more sustainable.
Fossil fuels are the most common form of energy. They include oil, coal, and natural gas. They began to form millions and millions of years ago when prehistoric https://leonardogiombini.it/2019/03/01/le-biomasse-i-processi-termochimici/ animals and plants passed away and were then buried beneath layers of sedimentary rock. When the conditions were right they were gradually transformed into carbon-rich compounds that, when burnt generate energy. These fossil fuels are non-renewable because they will run out in our lifetimes, or in many lives.
Renewable energy sources are continuously replenished. The primary renewable energy source is sunlight, which supplies warmth and light. We use it for our homes business, cars, and homes. Wind is a different renewable energy source, which generates electricity through spinning turbines. We have been using it since we first began to harness the wind for millennia. In addition, we employ biochemical processes to create the ethanol (a clear alcohol that can be used as fuel) from waste and crop residues.
Hydropower is the main renewable energy source in the United States, but biofuels and wind will soon overtake it. Hydropower is based on nature’s water cycle to harness the power of rapid-flowing water, which is then used for electricity generation.
