We require various energy sources to work and live. These include wind, solar geothermal, biomass, and geothermal sources. In addition to being an important source of electricity, these sources can also be used to heat and transport. They can also emit greenhouse gases when 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 comprise oil, coal and natural gas. They were formed millions of year ago when prehistoric animals and plants died and were buried under layers of sedimentary rocks. When the right conditions, they were gradually converted to carbon-rich substances that, when burned, generate energy. The fossil fuels cannot be renewable, as they’ll end up being depleted in our lifetimes or in a variety of lives.
Renewable energy sources On the other hand are continuously replenished. The most important renewable energy source is sunlight, which gives light and heat. We use it to power our homes and businesses and to drive our cars. Wind is another renewable energy source, which produces electricity by spinning turbines. We have been using it since the first discovered how to harvest the wind for millennia. We also use biological processes to make alcohol (a clear alcohol that can be used to fuel) from waste and crops.
As a result hydropower is by far the most important renewable energy source in the United States, though wind and biofuels are expected be the next to take over. Hydropower is a natural cycle to harness water’s rapid flow, which can be used to produce electricity.
