We require various energy sources to work and live. They include wind, solar and geothermal as well as biomass sources. These sources are not only a major source for electricity, but also can be used for heating and transport. These energy sources emit greenhouse gases when burned to create electricity. This means that there is a need for more sustainable energy sources.
Fossil fuels are the most widely used form of energy. They comprise oil, coal and natural gas. They began to form millions and millions of years ago when animals and plants of the past passed away and were then buried beneath layers of sedimentary rock. In the right conditions, these fossil fuels were slowly transformed into carbon-rich materials that, when burned generate energy. The fossil fuels cannot be renewable as they will run dry in our lifetimes, or in many years.
Renewable energy sources are replenished continuously. The sun is the largest source of renewable energy as it provides both light and heat. We use it to power our homes business, cars, and homes. Wind is another renewable energy source that generates electricity by spinning turbines. We have been using it since the first began to harness the wind for millennia. We use biological processes create the ethanol (a clear, alcohol-like substance that can be used to make fuel) from crops and waste.
Hydropower is the main renewable energy source in America, however biofuels and wind will soon take over. Hydropower is a natural cycle to harness the water’s rapid flow, which can be used to produce electricity.
