Diverse energy sources provide us with the power we require to live and work. These include wind, solar, geothermal, and biomass sources. In addition to being an important source of electricity they can also be used for heat and transport. The main challenge for these energy sources is that they can cause greenhouse gas emissions when they are burned to produce electricity. This results in the need for more environmentally sustainable energy sources.
The most common type of energy is the fossil fuels, which consist of coal oil, natural gas. They were formed thousands of years ago when prehistoric animals and plants died and were then buried under layers of sedimentary rocks. After that, under the proper conditions, they slowly transformed into carbon-rich substances that, when burned, generate energy. They are not renewable because they will run out in our lifetimes or even in many lifetimes.
Renewable energy sources are replenished regularly. The sun is the largest source of renewable energy since it supplies heat and light. We use it to power our homes business, cars, and homes. Wind is a different renewable energy source, which generates electricity through spinning turbines. We have been using it since people first began to harness the wind for millennia. Finally, we use biological processes to create alcohol (a clear alcohol that can be used to fuel) from waste and crops.
Among these sources hydropower is by far the most important renewable energy source in the United States, though wind and biofuels are expected become the dominant source in the near future. Hydropower draws on nature’s hydro cycle to harness the power of flowing water, which is used to generate electricity.
