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 they can also be used for heating and transport. These energy sources can emit greenhouse gases when they are burned to create electricity. This creates a need for more green energy sources.
Fossil fuels are the most well-known form of energy. They include coal, oil and natural gas. They were formed thousands of years ago when prehistoric animals and plants died and were buried under layers of sedimentary rocks. Then, under the appropriate conditions, they gradually transformed into carbon-rich compounds that, when ignited create energy. The fossil fuels cannot be renewable because they will run dry in our lifetimes, or in many lives.
Renewable energy sources however are continuously replenished. The most important renewable energy source is sunlight, which provides warmth and light. We use it to power our homes and businesses and to drive vehicles. Wind is an energy source that is renewable and generates electricity by spinning turbines. Since the first time people realized how to harness the wind and harness it, we have been using it for millennia. We utilize biological processes to create an ethanol (a alcohol-like substance that is clear and transparent that can be used to make fuel) from crops and waste.
Hydropower is the main renewable energy source in the United States, but biofuels and wind are likely to surpass it. Hydropower is based on nature’s water cycle to harness the power of flowing water, which is used to generate electricity.
