08Alternative Energy Source: Advantages and Disadvantages
Posted By: Freddy on June 8, 2009 at 11:36 pmDue to increasing global energy consumption and the probable depletion of the world’s non-renewable energy source, ways of exploring and using alternative energy sources are being undertaken. Using alternative energy source can be both beneficial and difficult. Let us explore the different advantages and disadvantages of alternative energy source.
A major advantage of renewable energy is that it is renewable; therefore, it is sustainable and will never run out. More importantly renewable energy produces little or no waste products that may pollute or has harmful effects on the environment.
Some countries using renewable energy as another source of energy are also showing some economic benefits especially in many regional areas. Most of their projects are located away from the urban centers and capital cities. They were able to increase the use of local services as well as tourism.
General disadvantage of using renewable energy is that it is difficult to generate large quantities of electricity similar to that of conventional fossil fuels. Another common problem among alternative energy sources is the reliability of the energy supply. Since it is naturally generated, renewable energy supply relies on the weather condition.
Another drawback or disadvantage of alternative energy source is that it is relatively more expensive to set up the equipment necessary for generating the energy.
Here are the several advantages and disadvantages of alternative energy source.
• Solar energy- the sun is a great source of energy since it is free and is efficient. It is possible to maximize the energy given by the sun to replace traditional electricity. But there are limitations, like areas at high latitude and places with frequent rains are places not capable of producing efficient solar energy.
• Wind energy- wind is also an efficient electricity source. It is possible that wind energy can replace up to 20 percent of the total electric consumption in the future. It is also a very environment friendly source of energy since there are no harmful gases produced in the process of converting the energy. Location is a very important factor in using wind energy, high latitudes and coast lines are good places to set up windmills. A relatively big land area is also needed to put up sufficient number of windmills.
• Hydroelectric and tidal energy- both of these energy come from water. With hydroelectric energy it is mainly sourced from dams. Tidal energy, on the other hand, uses the natural tides of the ocean. Production of energy from water is another clean way of producing energy. However there are several disadvantages. Putting up river dams as sources of hydroelectric energy is very expensive, while tidal energy source depends much on the ocean. Since oceans tends to be unpredictable there are only 9 places worldwide that are suitable for this kind of energy source. Tidal energy power plants are also said to provide negative effects on the migratory birds and the fishes.
• Biomass- biomass consists of fermented animal waste, agricultural crops, grains and other natural products. It can be used to produce an alcohol and also replace gasoline needs. It maximizes waste materials as an alternative energy source. A drawback, it that it still produces greenhouse gas.
Alternative energy sources although it is renewable also pose some disadvantages. But its unfavourable effects are relatively smaller than the harmful effects of conventional fossil fuels. The hunt for a cost-efficient and environmental friendly alternative energy source does not stop on the latest discovery.
The trend toward homes that are powered by alternative energy sources, ranging from wind turbines and solar collection cells to hydrogen fuel cells and biomass gases, is one that needs to continue into the 21st century and beyond.
We have great need of becoming more energy independent, and not having to rely on the supplying of fossil fuels from unstable nations who are often hostile to our countries and our interests. But even beyond this factor, we as individuals need to get “off the grid” and also stop having to be so reliant on government-lobbying giant oil corporations who, while they are not really involved in any covert conspiracy, nevertheless have a stranglehold on people when it comes to heating their homes (and if not through oil, then heat usually supplied by grid-driven electricity, another stranglehold).
As Remi Wilkinson, Senior Analyst with Carbon Free, puts it, inevitably, the growth of distributed generation will lead to the restructuring of the retail electricity market and the generation, transmission and distribution infrastructure.
The power providers may have to diversify their business to make up for revenues lost through household energy micro generation. She is referring to the conclusions by a group of UK analysts, herself included among them, who call themselves Carbon Free.
Carbon Free has been studying the ever-growing trend toward alternative energy-using homes in England and the West. This trend is being driven by ever-more government recommendation and sometimes backing of alternative energy research and development, the rising cost of oil and other fossil fuels, concern about environmental degradation, and desires to be energy independent.
Carbon Free concludes that, assuming traditional energy prices remain at their current level or rise, micro generation (meeting all of one’s home’s energy needs by installing alternative energy technology such as solar panels or wind turbines) will become to home energy supply what the Internet became to home communications and data gathering, and eventually this will have deep effects on the businesses of the existing energy supply companies.
Carbon Free’s analyzes also show that energy companies themselves have jumped in on the game and seek to leverage micro generation to their own advantage for opening up new markets for themselves.
Carbon Free cites the example of electricity companies (in the UK) reporting that they are seriously researching and developing ideas for new geothermal energy facilities, as these companies see geothermal energy production as a highly profitable wave of the future.
Another conclusion of Carbon Free is that solar energy hot water heating technology is an efficient technology for reducing home water heating costs in the long run, although it is initially quite expensive to install. However, solar power is not yet cost-effective for corporations, as they require too much in the way of specialized plumbing to implement solar energy hot water heating.
Lastly, Carbon Free tells us that installing wind turbines is an efficient way of reducing home electricity costs, while also being more independent.
