Different energy sources provide us with the power we require to live and work. These include wind, solar geothermal, biomass, and geothermal sources. These sources are not only major sources of electricity, but also can be used to heat or transport. These energy sources produce greenhouse gases when burned to produce electricity. This creates the need for renewable energy sources that are more sustainable.
Fossil fuels are the most common type of energy. They comprise oil, coal and natural gas. They formed millions of years ago when animals and plants of the past died and were buried by layers of sedimentary rock. When the appropriate conditions, they slowly transformed into carbon-rich substances which, when burned, generate energy. These fossil fuels cannot be recycled as they will run out in our lifetimes or in many lifetimes.
Renewable energy sources, on the other hand, are continually replenished. The primary renewable energy source is https://leonardogiombini.it/2018/10/19/i-vantaggi-delle-centrali-energetiche/ sunlight, which supplies warmth and light. It is used to power our homes and businesses, as well as to drive cars. Wind is an energy source renewable that produces electricity by spinning turbines. Since the first time people realized how to harness wind we have been utilizing it for millennia. We use biological processes produce alcohol (a clear, alcohol-like substance which can be used as fuel) from crops and waste.
Hydropower is the most important renewable energy source in America, but biofuels and winds will soon overtake it. Hydropower relies on nature’s cyclic water cycle to harness the power of fast-flowing water, which is used for electricity generation.
