Diverse energy sources provide us with the power we require to live and work. Solar, wind, geothermal and biomass are a few of the sources. In addition to being an important source of electricity, these sources can also be used to transport and heat. These energy sources emit greenhouse gases when burned to produce electricity. This leads to the need for more green energy sources.
The most popular kind of energy is fossil fuels, comprised of coal oil, natural gas. They were created millions of years ago when prehistoric animals and plants passed away and were buried under layers of sedimentary rocks. After that, under the right conditions, they slowly transformed into carbon-rich substances which, when burnt produce energy. These fossil fuels will not be renewable since they will be depleted in our lifetimes or in a number of lifetimes.
Renewable energy sources On the other hand are constantly replenished. The sun is the primary source of renewable energy, as it provides both heat and light. It is used to power our homes and businesses, as well as to drive our cars. Wind is a renewable energy source that produces electricity through spinning turbines. We have used it since humans first discovered how to harvest the wind for millennia. We utilize biological processes to create ethanol (a clear, alcohol-like substance which can be used as fuel) from food waste and crops.
Of all these sources, hydropower is the largest renewable energy source in the United States, though wind and biofuels are likely to be the next to take over. Hydropower is a natural cycle to harness water’s swift flow, which in turn is used to generate electricity.
