Different energy sources provide us with the power we require to live and work. These include solar, wind and geothermal as well as biomass sources. In addition to being the primary source of electricity, these sources are also used for transport and heat. The biggest issue for these energy sources is that they can cause greenhouse gas emissions when they are burned to produce electricity. This means that there is a need for renewable energy sources that are more sustainable.
The most commonly used kind of energy is called fossil fuels, which include coal oil, natural gas. They began to form millions of years ago when prehistoric plants and animals died and were covered by layers of sedimentary rock. After that, under the proper conditions, they gradually transformed into carbon-rich materials that, when burned, generate energy. These fossil fuels are non-renewable since they will exhaust in our lifetimes or in many lives.
Renewable energy sources, on the other hand are continuously replenished. The primary renewable energy source is sunlight, which produces warmth and light. We utilize it for our homes vehicles, businesses, and homes. Wind is another renewable energy source, which generates electricity through spinning turbines. We have been using it since people first discovered how to harvest the wind for millennia. In addition, we employ biochemical processes to create the ethanol (a clear alcohol that can be used as fuel) from waste and crop residues.
Hydropower is the largest renewable energy source in the United States, but biofuels and wind are likely to take over. Hydropower relies on nature’s water cycle to harness the power of fast-flowing water, which is used in turn to generate electricity.
