We need different energy sources to work and live. Geothermal, solar, wind and biomass are just a few of the sources. These sources aren’t only the primary source of electricity, but they can also be used to heat and transport. They can also emit greenhouse gases when they are burned to produce electricity. This means that there is a le biomasse i processi termochimici need for renewable energy sources that are more sustainable.

The most commonly used type of energy is fossil fuels, made up of coal, oil, and natural gas. They began to form millions of years ago when prehistoric plants and animals died and were covered by layers of sedimentary rock. After that, under the right conditions, they gradually transformed into carbon-rich materials that, when ignited create energy. These fossil fuels will not be renewable, as they’ll be depleted in our lifetimes or in a variety of lives.

Renewable energy sources On the other hand are continuously replenished. The sun is the main source of renewable energy, as it provides both heat and light. We utilize it for our homes, businesses, and cars. Wind is an energy source renewable that produces electricity by 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 make an ethanol (a clear alcohol that can be used to fuel) from waste and crop residues.

Hydropower is the largest renewable energy source in the United States, but biofuels and winds will soon surpass it. Hydropower draws on nature’s hydro cycle to harness the power of fast-flowing water, which is then used for electricity generation.
