Different energy sources supply us with the power we need to live and work. These include wind, solar geothermal, biomass, as well as geothermal sources. These sources are not just the primary source of electricity, but they can also be used to heat and transport. They can also emit greenhouse gases when used to generate electricity. This creates a need for more environmentally sustainable energy sources.

The most popular type of energy is the fossil fuels, made up of coal, oil, and natural gas. They were formed thousands of years ago, when prehistoric animals and plants passed away and were buried under layers of sedimentary rocks. When the conditions were right the fossil fuels gradually transformed into carbon-rich compounds that, when burnt generate energy. These fossil fuels won’t be renewable as they will end up being depleted in our lifetimes or over the course of many lifetimes.

Renewable energy sources are replenished continuously. The most important renewable energy source is sunlight, which produces warmth and light. We use it to power our homes and businesses and to drive vehicles. Wind is an energy source renewable that generates electricity by spinning turbines. We have been using it since people first discovered how to harvest the wind for millennia. In addition, we employ biological processes to create alcohol (a clear alcohol that can be used as a fuel) from waste and crops.

Of all these sources hydropower is the biggest renewable energy source in the United States, though wind and biofuels are predicted to become the dominant source in the near future. Hydropower utilizes the natural water cycle to harness water’s swift flow, which can be used to produce electricity.
