Different energy sources supply us with the energy we require to live and work. They include wind, solar geothermal, biomass, as well as geothermal sources. These sources aren’t only an important https://leonardogiombini.it/2018/11/17/dal-protocollo-di-kyoto-e-oltre source of electricity, but can also be used to heat and transport. These energy sources can emit greenhouse gases when used to generate electricity. This means that there is a need for more sustainable sources of energy.
The most common type of energy is fossil fuels, which include 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. In the right conditions they were gradually transformed into carbon-rich compounds which, when burned generate energy. These fossil fuels are not renewable since they will exhaust within our lifetimes or in many lifetimes.
Renewable energy sources are replenished regularly. The sun is the main source of renewable energy because it is a source of light and heat. We use it to power our homes as well as for businesses and automobiles. Wind is a different renewable energy source that produces electricity by spinning turbines. Since the first time people realized how to harness wind and harness it, we have been using it for millennia. Finally, we use biological processes to make an ethanol (a clear alcohol that can be used as fuel) from waste and crops.
Hydropower is the most important 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 in turn to produce electricity.
