Different energy sources supply us with the power we require to live and work. Solar, wind, geothermal and biomass are you could try this out among the sources. These sources are not just an important source of electricity, but can also be used to heat and transport. The biggest issue for these energy sources is that they could cause greenhouse gas emissions when burned to generate electricity. This is why there is a need for more environmentally sustainable energy sources.
The most widely used type of energy is fossil fuels, which consist of coal, oil, and natural gas. They were formed millions of year ago when prehistoric animals and plants died and were buried under layers of sedimentary rocks. In the right conditions, they were gradually converted to carbon-rich substances that, when ignited produce energy. These fossil fuels cannot be recycled because they will run out within our lifetimes or in a number of lifetimes.
Renewable energy sources however are constantly 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 an energy source that is renewable and produces electricity by spinning turbines. We have been using it since the first began to harness the wind for millennia. We use biological processes create alcohol (a clear, alcohol-like substance that can be used as fuel) from the waste of crops and other materials.
Of all these sources, hydropower is the largest renewable energy source in the United States, though wind and biofuels are likely to be the next to take over. Hydropower relies on nature’s water cycle to harness the power of fast-flowing water, which is used for electricity generation.
