We require various energy sources to work and live. These include wind, solar, geothermal, and biomass sources. These sources aren’t only a major source for electricity, but also can be used visite site to heat and transport. The biggest issue with these sources of energy is that they can create greenhouse gas emissions when used to generate electricity. This leads to the need for renewable energy sources that are more sustainable.
The most popular type of energy is fossil fuels, comprised of coal, oil, and natural gas. They were created thousands of years ago, when prehistoric animals and plants died and were buried under layers of sedimentary rocks. Under the right conditions the fossil fuels gradually transformed into carbon-rich compounds that, when burnt generate energy. These fossil fuels won’t be renewable since they will run dry in our lifetimes or over the course of many lifetimes.
Renewable energy sources however are continuously replenished. The sun is the main source of renewable energy since it supplies heat and light. We use it to power our homes, businesses, and cars. Wind is a different renewable energy source that generates electricity through spinning turbines. We have used it since humans first began to harness the wind for millennia. We also use biological processes to make alcohol (a clear alcohol that can be used as fuel) from crops and waste.
In the list of sources hydropower is the biggest renewable energy source in the United States, though wind and biofuels are predicted to be the next to take over. Hydropower is a natural cycle to harness water’s rapid flow, which produces electricity.
