Different energy sources provide us with the power we require to live and work. They include wind, solar and geothermal as well as biomass sources. In addition to being the primary source of electricity they can also be used for heat and transport. They can also emit greenhouse gases when they are burned to create electricity. This means that there is a need for more sustainable energy sources.
Fossil fuels are the most popular form of energy. They include coal, oil and natural gas. They were created thousands of years ago when prehistoric animals and plants died and were buried beneath layers of sedimentary rocks. Then, under the appropriate conditions, they gradually converted to carbon-rich substances which, when burnt, generate energy. These fossil fuels won't be renewable, as they'll end up being depleted in our lifetimes, or in many lifetimes.
Renewable energy sources On the other hand are continuously replenished. The primary renewable energy source is sunlight, which provides light and heat. We utilize it for our homes business, cars, and homes. Wind is another renewable energy source, which generates electricity by spinning turbines. We have been using it since the first began to harness the wind for millennia. We utilize biological processes to create alcohol (a clear, alcohol-like substance that can be used for fuel) from crops and waste.
Hydropower is the largest renewable energy source in America, however biofuels and wind are likely to surpass it. Hydropower is based on nature's water cycle to harness the power of swiftly flowing water, which is used to generate electricity.
