Alternative Energy – 6 New Concepts You Would Want to Know About

Offshore Wind FarmThere has been a continuous effort to minimize atmospheric carbon dioxide, which is a byproduct from burning fossils. More and more alternative energy sources had been discovered in an effort to save the environment from impending destruction related to the use of fossil fuels as energy source. These discoveries are quite promising. Here are some of them:
1. Algae Fuel. As the name itself suggests, algae fuel came from algae. The biomass and oxygen byproducts of algae during photosynthesis can be useful energy sources. Furthermore, algae biofuel may be produced industrially, without the need for a land or food crops. It is also proven to yield more oil than other biofuel sources.
2. Biogas Digestion. This involves utilization of the methane gas released by waste breakdown. The methane gas is collected from sewage systems and garbage through the use of biogas digesters. The collected gas is then refined and used as an energy source.
3. Biomass Briquettes. A very good substitute for charcoal, wherein plant matter is converted into compressed briquettes. The briquettes contain 70% the value of charcoal.
4. Biological Hydrogen Production. This involves the use of biological vectors like algae (more common) and bacteria. This process requires single-celled organisms to be placed in an anaerobic environment. Without oxygen, cellular respiration can’t take place and fermentation takes over. Hydrogen gas is its major byproduct. However, large-scale production of hydrogen gas through this process was hard. Researchers have developed a process to keep the cells alive in the year 2000. A meticulous work is being made to guarantee a well-organized process before large-scale productions will be pushed through. Once a mechanism is established, this production would absolutely meet our energy needs.
5. Offshore wind. The mechanism involved in generating energy is the same as regular wind farms. The only difference is that offshore wind farms are placed in the ocean. Since there are no trees, hills, or building to hinder, this technique doubles the energy generated from the wind turbines. There are more wind resources in deeper waters, thus more advanced floating wind turbines were developed just for the purpose.
6. Marine and Hydrokinetic Power. This energy is generated through the utilization of waves and marine currents. Different types of water turbines were strategically placed in deep marine waters, in open coastal and estuarine areas, and in fast-moving rivers so as to harness as much marine energy as these devices can possibly get.
For these alternative energy resources to become main stream, there should be a full comprehension of how these alternative energies work.

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.
