Different energy sources supply us with the energy we need to live and work. Solar, wind, geothermal and biomass are a few of the sources. In addition to being the primary source of electricity they can also be used for transportation and heating. These energy sources can emit greenhouse gases when burned to create electricity. This creates the need for greener https://leonardogiombini.it/2019/01/24/da-costruttore-le-biomasse-come-fondazioni/ sources of energy.
The most widely used type of energy is the fossil fuels, made up of coal oil, natural gas. They began to form millions and millions of years ago when animals and plants of the past died and were buried by layers of sedimentary rock. After that, under the right conditions, they slowly transformed into carbon-rich substances that, when burned create energy. These fossil fuels are not renewable since they will be exhausted in our lifetimes, or in many lifetimes.
Renewable energy sources are continuously replenished. The sun is the main source of renewable energy as it provides both light and heat. We use it for our homes business, cars, and homes. Wind is renewable energy source that generates electricity through spinning turbines. Since the first people discovered how to harness wind, we have been using it for millennia. In addition, we employ biochemical processes to create ethanol (a clear alcohol that can be used to fuel) from waste and crops.
Hydropower is the most important renewable energy source in America, however biofuels and winds will soon take over. Hydropower utilizes the natural water cycle to harness the water’s rapid flow, which in turn can be used to produce electricity.
