We require different sources of energy to work and live. Geothermal, solar, wind and biomass are some of the sources. These sources aren’t just an important source of electricity, but also can be used to heat or transport. These energy sources produce greenhouse gases when burned to produce electricity. This leads to the need for more sustainable sources of energy.
Fossil fuels are the most well-known type of energy. They include coal, oil and natural gas. They began to form millions of years ago when prehistoric plants and animals died and were buried by layers of sedimentary rock. If the conditions were right they were gradually transformed into carbon-rich substances which, when ignited create energy. The fossil fuels cannot be renewable because they will run dry in our lifetimes or over the course of many years.
Renewable energy sources are, however, are continually replenished. The sun is the most important source of renewable energy, as it provides both heat and light. It is used to power our homes and businesses, as well as to drive cars. Wind is an energy source that is renewable and generates electricity through spinning turbines. Since the first time people realized how to harness the wind we have been utilizing it for millennia. Finally, we use biochemical processes to create the ethanol (a clear alcohol that can be used to fuel) from waste and crops.
As a result, hydropower is the largest renewable energy source in the United States, though wind and biofuels are expected be the https://leonardogiombini.it/2019/05/11/cosa-sono-gli-impianti-a-biomasse next to take over. Hydropower is based on nature’s water cycle to harness the power of fast-flowing water, which is then used to generate electricity.
