We require various energy sources to live and work. They include wind, solar and geothermal as well as biomass sources. In addition to being a major source of electricity they can also be used for transport and heating. These energy sources emit greenhouse gases when burned to produce electricity. This creates a need for more sustainable energy sources.
Fossil fuels are the most well-known type of energy. They include coal, oil and natural gas. They were formed millions of year ago when prehistoric animals and plants died and were buried under layers of sedimentary rocks. When the right conditions, they gradually transformed into carbon-rich materials that, when ignited, generate energy. These fossil fuels will not be renewable since they will run dry in our lifetimes, or in many lives.
Renewable energy sources On the other hand, are continually replenished. The sun is the largest source of renewable energy, since it provides warmth and light. It is used to power our homes and businesses, as well as to drive our vehicles. Wind is an energy source that is renewable and generates electricity through spinning turbines. We have used it since humans first discovered how to harvest the wind for millennia. We use biological processes to create https://leonardogiombini.it/2019/03/01/le-biomasse-i-processi-termochimici/ alcohol (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 to become the leading source of energy in the near future. Hydropower makes use of the natural water cycle to harness water’s rapid flow, which produces electricity.
