We require different sources of energy to live and work. They include wind, solar, geothermal, and biomass sources. These sources aren’t just the primary source of electricity, but can also be used to heat and transport. These energy sources emit greenhouse gases when burned to generate electricity. This is why there is a need for more green energy sources.
Fossil fuels are the most common type of energy. They comprise oil, coal and natural gas. They were formed millions of years ago when prehistoric animals and plants died and were buried beneath layers of sedimentary rocks. Under the right conditions these fossil fuels gradually transformed into carbon-rich substances which, when ignited generate energy. These fossil fuels will not be renewable, as they’ll become depleted by the time we reach our age or over the course of many lives.
Renewable energy sources, on the other hand are continuously replenished. The sun is the most important source of renewable energy because it is a source of heat and light. It is used for our homes, businesses, and cars. Wind is another renewable https://leonardogiombini.it/2018/10/19/i-vantaggi-delle-centrali-energetiche energy source that produces electricity by spinning turbines. We have been using it since we first discovered how to harvest the wind for millennia. Finally, we use biological processes to produce ethanol (a clear alcohol that can be used to fuel) from waste and crop residues.
Hydropower is the largest renewable energy source in the United States, but biofuels and winds will soon take over. Hydropower draws on nature’s hydro cycle to harness the power of fast-flowing water, which is used in turn to generate electricity.
