Diverse energy sources provide us with the power we require to live and work. Geothermal, solar, wind and biomass are just a few of the sources. These sources are not just major sources https://leonardogiombini.it/2018/11/17/dal-protocollo-di-kyoto-e-oltre of electricity, but they can also be used to heat or transport. The biggest issue for these energy sources is that they can create greenhouse gas emissions when used to generate electricity. This creates a need for more environmentally sustainable energy sources.
The most commonly used type of energy is fossil fuels, made up of coal oil, natural gas. They were formed millions of years ago when prehistoric animals and plants died and were buried by layers of sedimentary rock. In the proper conditions, they gradually transformed into carbon-rich compounds that, when burned create energy. These fossil fuels are not renewable since they will exhaust in our lifetimes, or in many lifetimes.
Renewable energy sources however are continuously replenished. The most important renewable energy source is sunlight, which gives light and heat. We utilize it for our homes, businesses, and cars. Wind is a different renewable energy source, which generates electricity by spinning turbines. Since the first time people realized how to harness the wind we have been utilizing it for millennia. We use biological processes to produce alcohol (a alcohol-like substance that is clear and transparent which can be used as fuel) from food waste and crops.
Hydropower is the largest renewable energy source in America, however biofuels and winds will soon surpass it. Hydropower makes use of the natural water cycle to harness water’s swift flow, which can be used to produce electricity.
