We require different sources of energy to live and work. These include solar, wind, geothermal, and biomass sources. These sources are not just an important source of electricity, but can also be used for heating and transport. These energy sources produce greenhouse gases when they are burned to generate electricity. This is why there is a need for more environmentally sustainable energy sources.
The most common type of energy is fossil fuels, comprised of coal oil, natural gas. They began to form millions of years ago when prehistoric animals and plants died and were covered by layers of sedimentary rock. In the right conditions the fossil fuels gradually transformed into carbon-rich compounds that, when burned generate energy. These fossil fuels will not be renewable because they will https://leonardogiombini.it/2019/03/01/le-biomasse-i-processi-termochimici run dry in our lifetimes or over the course of many years.
Renewable energy sources are continuously replenished. The most important renewable energy source is sunlight, which provides warmth and light. We use it for our homes as well as for businesses and automobiles. Wind is another renewable energy source, which generates electricity through spinning turbines. Since the first people discovered how to harness wind and harness it, we have been using it for millennia. We also use biological processes to create the ethanol (a clear alcohol that can be used to create fuel) from crops and waste.
Hydropower is the most important renewable energy source in the United States, but biofuels and wind will soon take over. Hydropower uses the natural water cycle to harness the power of water’s rapid flow, which produces electricity.
