We require a variety of energy sources to work and live. Geothermal, solar, wind and biomass are just a few of the sources. In addition to being an important source of electricity they are also used for transport and heat. The biggest issue with these energy sources is that they could cause greenhouse gas emissions when burned to produce electricity. This leads to the need for more green energy sources.
Fossil fuels are the most popular form of energy. They include coal, oil and natural gas. They began to form millions and millions of years ago when prehistoric plants and animals died and were covered by layers of sedimentary rock. When the conditions were right the fossil fuels gradually transformed into carbon-rich compounds which, when ignited, produce energy. These fossil fuels are non-renewable as they will run out in our lifetimes or in many lifetimes.
Renewable energy sources are replenished regularly. The sun is the primary source of renewable energy, since it supplies heat and light. We utilize it for my latest blog post our homes vehicles, businesses, and homes. Wind is an energy source renewable that produces electricity through spinning turbines. We have used it since humans first discovered how to harvest the wind for millennia. We use biological processes to create an ethanol (a alcohol-like substance that is clear and transparent that can be used to make fuel) from food waste and crops.
Hydropower is by far the most important renewable energy source in America, however biofuels and winds will soon take over. Hydropower relies on nature’s cyclic water cycle to harness the power of rapid-flowing water, which is used for electricity generation.
