We require various energy sources to work and live. These include solar, wind geothermal, biomass, and geothermal sources. In addition to being an important source of electricity, these sources are also used for transportation and heating. The major issue for these energy sources is that they can cause greenhouse gas emissions when used to generate electricity. This leads to the need for more green energy sources.
The most common kind of energy is called fossil fuels, made up of coal, oil, and natural gas. They were formed millions of years ago when prehistoric animals and plants died and were buried under layers of sedimentary rocks. After that, under the right conditions, they were gradually transformed into carbon-rich compounds which, when burned create energy. These fossil fuels will not be renewable, as they’ll end up being depleted in our lifetimes or over the course of many lifetimes.
Renewable energy sources are, however are constantly replenished. The sun is the primary source of renewable energy, since it provides warmth and light. We use it to power our homes and businesses, as well as to drive vehicles. Wind is a renewable energy source that generates electricity through spinning turbines. We have been using it since we first began to harness the wind for millennia. We utilize biological processes to create alcohol (a alcohol-like substance that is clear and transparent that can be used to make fuel) from waste and crops.
Hydropower is the most important renewable energy source in the United States, but biofuels and winds will soon take over. Hydropower relies on nature’s water cycle to harness the power of swiftly flowing water, which is then used for electricity generation.
