Different energy sources supply us with the power find out this here we require to live and work. Geothermal, solar, wind and biomass are among the sources. These sources are not only the primary source of electricity, but they can also be used to heat or transport. These energy sources emit greenhouse gases when burned to produce electricity. This leads to the need for more environmentally sustainable energy sources.
Fossil fuels are the most common form of energy. They include coal, oil and natural gas. They were formed thousands of years ago, when prehistoric animals and plants passed away and were buried under layers of sedimentary rocks. After that, under the appropriate conditions, they slowly transformed into carbon-rich substances that, when burned create energy. These fossil fuels are non-renewable since they will be exhausted in our lifetimes or in many lifetimes.
Renewable energy sources are, however are constantly replenished. The primary renewable energy source is sunlight, which provides heat and light. We use it to power our homes as well as for businesses and automobiles. Wind is an energy source renewable that produces electricity through spinning turbines. Since the first people discovered how to harness the wind, we have been using it for millennia. We use biological processes create an ethanol (a clear, alcohol-like substance that can be used as fuel) from food 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 water’s swift flow, which can be used to produce electricity.
