Different Energy Sources

Diverse energy sources provide us with the energy we need to live and work. Geothermal, solar, wind and biomass are a few of the sources. In addition to being an important source of electricity they can also be used for transport and heat. These energy sources emit greenhouse gases when they are used to generate electricity. This is why it is necessary to find renewable energy sources that are more sustainable.

The most widely used kind of energy is fossil fuels, made up of coal oil, natural gas. They were formed millions of year ago when prehistoric animals and plants passed away and were buried under layers of sedimentary rocks. If the conditions were right they were gradually transformed into carbon-rich compounds which, when ignited, produce energy. These fossil fuels won’t be renewable because they will be depleted in our lifetimes, or in many lifetimes.

Renewable energy sources are constantly replenished. The most important renewable energy source is sunlight, which produces heat and light. It is used to power our homes and businesses as well to drive vehicles. Wind is an energy source renewable that generates electricity by spinning turbines. Since the first people discovered how to harness wind we have been utilizing it for millennia. In the end, we employ biological processes to produce ethanol (a clear alcohol that can be used to create fuel) from waste and crops.

As a result hydropower is by far the most important renewable energy source in the United States, though wind and biofuels are likely to become the dominant source in the near future. Hydropower utilizes the natural water cycle to harness water’s swift flow, which in turn can be used to produce electricity.
