Different Energy Sources

We require different sources of energy to live and work. Solar, wind, geothermal and biomass are a few of the sources. These sources aren’t only an important source this post of electricity, but they can also be used for heating and transport. These energy sources emit greenhouse gases when burned to create electricity. This creates a need for more environmentally sustainable energy sources.

Fossil fuels are the most common form of energy. They include coal, oil and natural gas. They were formed millions of years ago when prehistoric animals and plants died and were buried under layers of sedimentary rocks. Under the right conditions they were slowly transformed into carbon-rich materials that, when burnt produce energy. These fossil fuels won’t be renewable as they will end up being depleted in our lifetimes, or in many lifetimes.

Renewable energy sources are, however are constantly replenished. The most important renewable energy source is sunlight, which gives heat and light. It is used to power our homes and businesses and to drive our vehicles. Wind is an energy source renewable that produces electricity by spinning turbines. We have been using it since people first began to harness the wind for millennia. We employ biological processes to create alcohol (a clear, alcohol-like substance that can be used as fuel) from the waste of crops and other materials.

Hydropower is the most important renewable energy source in the United States, but biofuels and wind are likely to overtake it. Hydropower is based on nature’s water cycle to harness the power of flowing water, which is used for electricity generation.
