We require different sources of energy to live and work. Solar, wind, geothermal and biomass are just a few of the sources. These sources aren’t just the primary source of electricity, but they can also be used for heating and transport. The major issue with these energy sources is that they may cause greenhouse gas emissions https://leonardogiombini.it/2020/06/02/primi-3-punti-chiave-di-unesperienza-centralizzata when used to generate electricity. This results in the need for more environmentally sustainable energy sources.
The most commonly used kind of energy is called fossil fuels, comprised of coal oil, natural gas. They formed millions of years ago when animals and plants of the past died and were covered by layers of sedimentary rock. Under the right conditions these fossil fuels slowly transformed into carbon-rich materials which, when ignited create energy. These fossil fuels will not be renewable because they will run dry in our lifetimes, or in many years.
Renewable energy sources however, are continually replenished. The sun is the most important source of renewable energy since it supplies light and heat. We use it to power our homes business, cars, and homes. Wind is an energy source that is renewable and generates electricity through spinning turbines. Since the first people discovered how to harness wind, we have been using it for millennia. In addition, we employ biological processes to produce the ethanol (a clear alcohol that can be used to fuel) from crops and waste.
Hydropower is the main renewable energy source in America, but biofuels and wind are likely to take over. Hydropower relies on nature’s cyclic water cycle to harness the power of fast-flowing water, which is then used in turn to produce electricity.
