Different energy sources supply us with the energy we require to live and work. Geothermal, solar, wind and biomass are a few of the sources. In addition to being the primary source of electricity, these sources can also be used for transportation and heating. The main challenge with these sources of energy is that they can cause greenhouse gas emissions when they are burned to produce electricity. This leads to the need for more sustainable energy sources.
Fossil fuels are the most widely used type of energy. They include coal, oil and natural gas. They were formed millions of years ago when prehistoric plants and animals died and were buried under layers of sedimentary rock. Then, under the right conditions, they gradually transformed into carbon-rich compounds which, when burnt produce energy. The fossil fuels cannot be renewable because they will end up being depleted in our lifetimes or in a variety of years.
Renewable energy sources are continuously replenished. The primary renewable energy source is sunlight, which gives warmth and light. We use it to power our homes and businesses and to drive vehicles. Wind is another renewable energy source, which generates electricity through spinning turbines. Since the first people discovered how to harness wind and harness it, we have been using it for millennia. We utilize biological processes to produce ethanol (a clear, alcohol-like substance which can be used as fuel) from the waste of crops and other materials.
Hydropower is the largest renewable energy source in America, however biofuels and wind are likely to surpass it. Hydropower draws on nature’s hydro cycle to harness the power of flowing water, which is used in turn to generate electricity.
