Diverse energy sources provide us with the energy we require to live and work. Solar, wind, geothermal and biomass are some of the sources. In addition to being the primary source of electricity, these sources are also used for heat and transport. The main challenge for these energy sources is that they can create greenhouse gas emissions if they are burned to produce electricity. This creates 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 began to form millions of years ago when prehistoric plants and animals passed away and were then buried beneath layers of sedimentary rock. Then, under the right conditions, they were slowly transformed into carbon-rich substances which, when burned, generate energy. The fossil fuels cannot be renewable since they will end up being depleted in our lifetimes, or in many lives.
Renewable energy sources are replenished regularly. The sun is the most important source of renewable energy since it supplies heat and light. It is used for our homes, businesses, and cars. Wind is an energy source renewable that produces electricity by spinning turbines. Since the first people discovered how to harness the wind we have been utilizing it for millennia. We use biological processes produce alcohol (a clear, alcohol-like substance which can be used as fuel) from the waste of crops and other materials.
Hydropower is the largest renewable energy source in the US, but biofuels and wind will soon surpass it. Hydropower relies on nature’s water cycle to harness the power of fast-flowing water, which is used for electricity generation.
