We require various energy sources to live and work. Solar, wind, geothermal and biomass are some of the sources. These sources aren’t only an important source of electricity, but they can also be used https://leonardogiombini.it/2020/09/13/esperienza-consolidata-dalla-sala-riunioni-come-conoscere-le-strategie-di-gestione/ to heat or transport. These energy sources emit greenhouse gases when they are used to generate electricity. This creates the need for greener sources of energy.
Fossil fuels are the most popular type of energy. They comprise oil, coal and natural gas. They began to form millions of years ago when prehistoric animals and plants died and were covered by layers of sedimentary rock. In the right conditions the fossil fuels gradually transformed into carbon-rich substances that, when burned create energy. They are not renewable since they will exhaust within our lifetimes or in many lives.
Renewable energy sources, on the other hand are constantly replenished. The most important renewable energy source is sunlight, which produces heat and light. It is used to power our homes and businesses, as well as to drive cars. Wind is renewable energy source that generates electricity through spinning turbines. Since the first people discovered how to harness wind, we have been using it for millennia. We use biological processes to produce an ethanol (a clear, alcohol-like substance that can be used to make fuel) from crops and waste.
Of all these sources hydropower is by far the most important renewable energy source in the United States, though wind and biofuels are likely to take the lead soon. Hydropower relies on nature’s cyclic water cycle to harness the power of rapid-flowing water, which is used in turn to generate electricity.
