Different energy sources supply us with the energy we require to live and work. These include wind, solar geothermal, biomass, and geothermal sources. In addition to being a major source of electricity, these sources are also used for transport and heat. These energy sources emit greenhouse gases when burned to generate electricity. This is why there is a need for more environmentally sustainable energy sources.
Fossil fuels are the most widely used form of energy. They comprise oil, coal and natural gas. They began to form millions and millions of years ago when prehistoric plants and animals died and were buried by layers of sedimentary rock. When the conditions were right, these fossil fuels were gradually transformed into carbon-rich compounds which, when burned generate energy. These fossil fuels cannot be recycled since they will be exhausted within our lifetimes or in description a number of lifetimes.
Renewable energy sources On the other hand are constantly replenished. The primary renewable energy source is sunlight, which gives warmth and light. We use it for our homes vehicles, businesses, and homes. Wind is an energy source that is renewable and produces electricity through spinning turbines. Since the first time people realized how to harness the wind we have been utilizing it for millennia. We utilize biological processes to produce an ethanol (a clear, alcohol-like substance which can be used as fuel) from waste and crops.
Hydropower is the main renewable energy source in America, however biofuels and winds will soon overtake it. Hydropower utilizes the natural water cycle to harness the water’s rapid flow, which is used to generate electricity.
