Sources of Green Energy Have Problems
With most things, you are told to weigh the positive aspects against the disadvantages, and take the information to make your decision. When you do this with Green Energy Sources, there are actually down sides, but none as awful as the possibility of running out of energy. Even if global warming just isn’t as harmful as some say, using green energy sources is a good idea. The most important benefit to using green energy is that it is clean and doesn’t pollute the air with anything toxic. Not only that, it is renewable, therefore it will never be used up, like oil is about to undertake.
The price of setting up green energy methods is very high but once it is up and running the maintenance cost is minimal. Some other difficulties can be the consistency of such power. Solar and wind energy can easily produce electrical energy effectively however modifications in the weather may cause a short term decline. Many are concerned that setting up wind turbines require a lot of property and might have to cut back on farmland. A number of green energy sources, including wave energy, require very specific conditions for it to be effective. It takes geologically unstable regions of the planet to be able to use geothermal energy.
There are ways around most of the arguments against green energy sources, for instance substituting one location for another. Wind turbines can be installed near the coast if they need more space, in fact a study shows when they are in the ocean they can generate more electricity. Weather might not be able to often be controlled, however the disturbances don’t last every day, and eventually they pass. For solar energy, emergency generators can be used if the level of sunlight is not available in sufficient amounts. There are actually ways around most arguments, but some people don’t want things to change, unless it becomes absolutely necessary. We have to carry on to do research to improve our current technology and to discover new green energy sources.
In Hawaii and Japan, they are experimenting with ocean thermal energy where power is actually created by the various changes in water temperature. Only about 7% of the power in the United States is coming from green energy methods. It was higher than that 11 years ago, but the concern pertaining to running out of energy appears to go up and down. Society has a way of desiring things to get done when there seems to be scarcity but change their minds when it improves.
There are a variety of options for green energy such as bio-diesel, biomass, geothermal, wind, water and solar. If there was as much money to be made harnessing these kinds of energy sources as there is by using oil, they would probably be available for everyone. If oil suddenly dried out, then the oil companies would be scrambling to find a way to benefit from a particular source. The sad part is these companies are just looking to profit than to be beneficial citizens of the earth.
