We require different sources of energy to live and work. They include wind, solar, geothermal, and biomass sources. In addition to being a major source of electricity, these sources are also used for transportation and heating. The main issue with these sources of energy is that they can cause greenhouse gas emissions if they are burned to produce electricity. This is why there is a need for more environmentally sustainable energy sources.
Fossil fuels are the most well-known type of energy. They include oil, coal, and natural gas. They formed millions of years ago when prehistoric plants and animals died and were buried under layers of sedimentary rock. In the right conditions, they were gradually transformed into carbon-rich materials which, when burnt, generate energy. They are not renewable since they will be exhausted within our lifetimes or in many lifetimes.
Renewable energy sources however are constantly replenished. The primary renewable energy source is sunlight, which supplies light and heat. It is used for our homes vehicles, businesses, and homes. Wind is a different renewable energy source, which generates electricity through spinning turbines. Since the first people discovered how to harness the wind, we have been using it for millennia. In addition, we employ biological processes to produce alcohol (a clear alcohol that can be used as a fuel) from crops and waste.
Hydropower is by far the most important renewable energy source in the United States, but biofuels and wind will soon take over. Hydropower relies on nature’s water cycle to harness the power of official website flowing water, which is used for electricity generation.
