Different energy sources provide us with the energy we need to live and work. These include wind, solar geothermal, biomass, as well as geothermal sources. In addition to being a major source of electricity they can also be used for transportation and heating. The main issue with these sources of energy is that they can create greenhouse gas emissions when burned to generate electricity. This is why it is necessary to find more sustainable energy sources.
The most common type of energy is fossil fuels, comprised of coal, oil, and natural gas. They were created thousands of years ago, when prehistoric animals and plants died and were buried under layers of sedimentary rocks. Then, under the appropriate conditions, they slowly transformed into carbon-rich substances that, when burned create energy. These fossil fuels won’t be renewable as they will become depleted by the time we reach our age or in a number of lifetimes.
Renewable energy sources are replenished continuously. The sun is the most important source of renewable energy since it supplies heat and light. We use it to power our homes as well as for businesses and automobiles. Wind is a renewable energy source that generates electricity through spinning turbines. Since the first time people realized how to harness the wind in the past, we have been using it for millennia. We use biological processes produce ethanol (a alcohol-like substance that is clear and transparent that can be used for fuel) from waste and crops.
Hydropower is the most important renewable energy source in the US, but biofuels and wind are likely to overtake it. Hydropower is a natural cycle to harness water’s swift flow, which is used to generate electricity.
