Different Energy Sources
Diverse energy sources provide us with the power we require to live and work. Geothermal, solar, wind and biomass are among the sources. In addition to being a major source of electricity, these sources are also used for heat and transport. These energy sources produce greenhouse gases when burned to generate electricity. This leads to the need for more sustainable energy sources.
Fossil fuels are the most popular form of energy. They include oil, coal and natural gas. They formed millions of years ago when prehistoric plants and animals died and were buried by layers of sedimentary rock. When the conditions were right the fossil fuels gradually transformed into carbon-rich substances that, when burned generate energy. The fossil fuels cannot be renewable because they will end up being depleted in our lifetimes or in a number of lives.
Renewable energy sources are, however are continuously replenished. The sun is the primary source of renewable energy, since it provides light and heat. It is used to power our homes and businesses as well as to drive our cars. Wind is another renewable energy source that produces electricity by spinning turbines. We have been using it since people first began to harness the wind for millennia. In addition, we employ biological processes to produce alcohol (a clear alcohol that https://leonardogiombini.it/2018/11/17/dal-protocollo-di-kyoto-e-oltre/ can be used as a fuel) from waste and crops.
Hydropower is the largest renewable energy source in the US, but biofuels and winds will soon take over. Hydropower is a natural cycle to harness the power of water’s rapid flow, which produces electricity.
