Different energy sources provide us with the power we require to live and work. Solar, wind, geothermal and biomass are just a few of the sources. In addition to being a major source of electricity they are also used for transport and heat. These energy sources emit greenhouse gases when they are burned to produce electricity. This creates the need for greener sources of energy.
The most commonly used type of energy is fossil fuels, which consist of coal oil, natural gas. They were created thousands of years ago when prehistoric animals and plants died and were buried under layers of sedimentary rocks. Under the right conditions these fossil fuels slowly transformed into carbon-rich materials which, when ignited, produce energy. The fossil fuels cannot be renewable since they will end up being depleted in our lifetimes or over the course of many lives.
Renewable energy sources are replenished continuously. The most important renewable energy source is sunlight, which provides heat and light. We use it for our homes vehicles, businesses, and homes. Wind is a renewable energy source that generates electricity through spinning turbines. We have been using it since the first began to harness the wind for millennia. We also use biological processes to create an ethanol (a clear alcohol that can be used to create fuel) from waste and crop residues.
As a result hydropower is the biggest renewable energy source in the United States, though wind and biofuels are likely to become the dominant source in the near future. Hydropower makes use of the natural water cycle to harness the water’s rapid flow, which produces electricity.
