We need different energy sources to live and work. Geothermal, solar, wind and biomass are a few of the sources. These sources are not only the primary source of electricity, but also can be used to heat or transport. The biggest issue with these energy sources is that they may cause greenhouse gas emissions when burned to generate electricity. This creates a need for more green energy sources.
Fossil fuels are the most popular form of energy. They include oil, coal, and natural gas. They began to form millions of years ago when prehistoric plants and animals died and were buried under layers of sedimentary rock. When the conditions were right, these fossil fuels were gradually transformed into carbon-rich substances that, when burnt generate energy. These fossil fuels won’t be renewable as they will become depleted by the time we reach our age or in a variety of years.
Renewable energy sources On the other hand are continuously 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 a renewable energy source that produces electricity through spinning turbines. We have been using it since we first discovered how to harvest the wind for https://leonardogiombini.it/2019/05/11/cosa-sono-gli-impianti-a-biomasse/ millennia. We also use biological processes to produce ethanol (a clear alcohol that can be used as fuel) from waste and crops.
Hydropower is by far the most important renewable energy source in America, but biofuels and winds will soon overtake it. Hydropower is based on nature’s water cycle to harness the power of rapid-flowing water, which is then used in turn to produce electricity.
