What You Need to Know About Alternative Energy

solar energy panels and wind turbinesFossil fuels are said to be the largest source of energy. However, it is a known fact that fossil fuels came from decomposed dead organisms millions of years ago, which means this energy source is not renewable. Well, strictly speaking it is renewable; however by the time it is renewed, we are long gone. Remember that the formation of fossil fuels take millions of years and existing viable reserves are being used up much faster than the new ones are being formed. Furthermore, the use of fossils causes serious environmental destruction. Statistics show that 21.3 gigatonnes of carbon dioxide is produced by the burning of fossil fuels every year. And the bad news is only half of that amount is being absorbed by natural processes (like photosynthesis in plants). Half of that is suspended in the atmosphere, greatly contributing to global warming. Because of this serious adverse effect, the use of alternative energy has become a global movement. Alternative energy, as the name suggests, is any energy source that can be utilized as a substitute for fossil fuels.

Solar Energy
Solar power is the best alternative energy source out there, as far as the environment is concerned. With the electricity cost increasing constantly, a lot of people nowadays have actually considered installing solar-energy panels at home. Not only does solar energy help you save dollars on electricity, but it is a huge help in decreasing enormous levels of carbon dioxide in the atmosphere. Although installation of solar energy panels will cost a small fortune, it’s a one-time investment. You could save much more than you paid for while saving mother earth all together.

Wind Energy
Wind power was known to have been used since 5000 BC. Back then, wind energy was used to fuel ships, water pumps, and grinders. Windmills were invented to generate more energy from wind. At present, wind energy is considered to be the most promising alternative energy source. It is cheaper, pollution-free, and more accessible. But like solar energy, it also has drawbacks. To generate more useful amounts of wind power, a lot of wind generators are needed. The maintenance of a wind farm can be quite expensive. However, the greater the number of the facilities built, the less costly wind power is.

Geothermal Energy
This type of alternative energy involves the use of the Earth’s natural heat to boil water, thus generating useful heat energy. This is also a very promising energy source.

Presently, there is a continued effort in finding more alternative energy sources which can be made viable, such as biomass briquettes and algae fuel.
