We need different energy sources to work and live. These include wind, solar and geothermal as well as biomass sources. In addition to being a my latest blog post major source of electricity, these sources can also be used for transport and heat. These energy sources produce greenhouse gases when burned to generate electricity. This results in the need for more environmentally sustainable energy sources.

Fossil fuels are the most well-known form of energy. They comprise oil, coal and natural gas. They were formed thousands of years ago when prehistoric animals and plants died and were then buried under layers of sedimentary rocks. After that, under the right conditions, they were gradually converted to carbon-rich substances which, when burned, generate energy. The fossil fuels cannot be renewable as they will be depleted in our lifetimes, or in many years.

Renewable energy sources are, however are continuously replenished. The most important renewable energy source is sunlight, which provides warmth and light. We use it to power our homes as well as for businesses and automobiles. Wind is an energy source that is renewable and produces electricity by spinning turbines. We have used it since humans first began to harness the wind for millennia. We utilize biological processes to create an ethanol (a clear, alcohol-like substance that can be used for fuel) from waste and crops.

As a result hydropower is the most significant renewable energy source in the United States, though wind and biofuels are expected become the leading source of energy in the near future. Hydropower utilizes the natural water cycle to harness the water’s rapid flow, which produces electricity.
