We require various energy sources to work and live. Geothermal, solar, wind and biomass are a few of the sources. These sources aren’t only the primary source of electricity, but can also be used for heating and transport. The major issue for these energy sources is that they could cause greenhouse gas emissions when they are burned to produce electricity. This results in the need for more sustainable energy sources.
The most widely used type of energy is fossil fuels, which include coal oil, natural gas. They were formed millions of years ago when prehistoric animals and plants died and were buried under layers of sedimentary rocks. When the conditions were right, these fossil fuels were gradually transformed into carbon-rich substances that, when burnt produce energy. These https://leonardogiombini.it/2018/06/02/leonardo-giombini-e-le-energie-rinnovabili/ fossil fuels are not renewable as they will run out in our lifetimes, or in many lifetimes.
Renewable energy sources are, however, are continually replenished. The most important renewable energy source is sunlight, which provides heat and light. We use it to power our homes, businesses, and cars. Wind is another renewable energy source, which generates electricity through spinning turbines. Since the first time people realized how to harness wind and harness it, we have been using it for millennia. We use biological processes to produce the ethanol (a clear, alcohol-like substance that can be used as fuel) from crops and waste.
In the list of sources hydropower is the most significant renewable energy source in the United States, though wind and biofuels are expected become the dominant source in the near future. Hydropower utilizes the natural water cycle to harness the water’s rapid flow, which can be used to produce electricity.
