We need different energy sources to work and live. Geothermal, solar, wind and biomass are a few of the sources. In addition to being an important source of electricity, these sources can also be used to transportation and heating. The main challenge with these sources of energy is that they can cause greenhouse gas emissions when used to generate electricity. This is why there is a need for more green energy sources.

Fossil fuels are the most well-known form of energy. They include oil, coal, and natural gas. They began to form millions and millions of years ago when prehistoric animals and plants died and were buried by layers of sedimentary rock. In the right official website conditions, they gradually transformed into carbon-rich materials which, when burnt produce energy. These fossil fuels are not renewable since they will be exhausted in our lifetimes, or in many lifetimes.

Renewable energy sources On the other hand are continuously replenished. The most important renewable energy source is sunlight, which gives heat and light. We use it to power our homes, businesses, and cars. Wind is renewable energy source that generates electricity through spinning turbines. Since the first people discovered how to harness the wind and harness it, we have been using it for millennia. Finally, we use biological processes to make alcohol (a clear alcohol that can be used as a fuel) from crops and waste.

Hydropower is the largest renewable energy source in America, however wind and biofuels will soon take over. Hydropower relies on nature’s cyclic water cycle to harness the power of swiftly flowing water, which is then used for electricity generation.
