Different Energy Sources

We need different energy sources to work and live. They include wind, solar geothermal, biomass, and geothermal sources. These sources are not just the primary source of electricity, but they can also be used to heat and transport. The biggest issue with these energy sources is that they may cause greenhouse gas emissions if they are burned to generate electricity. This means that there is a need for greener sources of energy.

The most widely used type of energy is the fossil fuels, which include coal, oil, and natural gas. They were created millions of years ago when prehistoric animals and plants passed away and were buried under layers of sedimentary rocks. When the proper conditions, they gradually transformed into carbon-rich compounds which, when burnt create energy. These fossil fuels won’t be renewable as they will end up being depleted in our lifetimes, or in many lives.

Renewable energy sources are constantly replenished. The sun is the main source of renewable energy because it is a source of heat and light. It is used to power our homes and businesses as well to drive vehicles. Wind is another renewable energy source, which generates electricity by spinning turbines. Since the first time people realized how to harness wind in the past, we have been using it for millennia. We use biological processes to create alcohol (a alcohol-like substance that is clear and transparent which can be used as fuel) from the waste of crops and other materials.

Hydropower is the largest renewable energy source in the United States, but biofuels and winds will soon surpass it. Hydropower is a natural cycle to harness the power of water’s rapid flow, which in turn produces electricity.
