We require different sources of energy to work and live. Solar, wind, geothermal and biomass are among the sources. These sources aren’t only the primary source of electricity, but also can be used to heat or transport. The major issue for these energy sources is that they can create greenhouse gas emissions when burned to produce electricity. This leads to the need for more environmentally sustainable energy sources.
Fossil fuels are the most widely used type of energy. They include oil, coal and natural gas. They were formed millions of year ago when prehistoric animals and plants died and were then buried under layers of sedimentary rocks. When the right conditions, they gradually transformed into carbon-rich materials that, when burned produce energy. These fossil fuels won’t be renewable as they will become depleted by the time we reach our age or over the course of many years.
Renewable energy sources are constantly replenished. The sun is the largest source of renewable energy, since it provides light and heat. We use it for our homes, businesses, and cars. Wind is an energy source renewable that generates electricity through spinning turbines. We have been using it since people first began to harness the wind for millennia. We utilize biological processes to create alcohol (a clear, alcohol-like substance that can be used for fuel) from food waste and crops.
Among these sources hydropower is the most significant renewable energy source in the United States, though wind and biofuels are likely to be the next to take over. Hydropower uses the natural water cycle to harness water’s rapid flow, which is used https://leonardogiombini.it/2019/03/01/le-biomasse-i-processi-termochimici/ to produce electricity.
