With most things, you are advised to weigh the advantages against the disadvantages, and take the knowledge to make your decision. When you do this with Green Energy Sources, you will discover disadvantages, but none as bad as the possibility of running out of energy. Whether or not there is really global warming, we should certainly not shun the idea of employing green energy sources. The biggest gain to using green energy is that it is clean and doesn’t pollute the air with anything poisonous. In contrast to fossil fuels like oil, green energy is renewable so we would never run out of it.
A drawback to implementing green energy is the original start up cost is rather high but it does not cost very much to operate once it is set up. As for energy production, there is a possibility that the amount of energy being produced is not reliably established. Solar and wind energy can certainly produce electricity effectively however changes in the weather may cause a short term decline. Some feel that constructing wind turbines will cause the amount of farmland to be diminished. Other styles of green energy are not sensible for every place like wave energy can only be set up in locations that get 16 feet or higher waves. In places that are not really geologically unpredictable, it is not feasible to setup a geothermal energy.
While in some cases, setting up green energy may seem impractical, there are ways around it to make it occur anyway. Wind turbines can be set up near the shoreline if they need extra space, in fact a study shows when they are in the ocean they can generate more electricity. Changes in the weather are generally unpredictable but we can safely assume changes will happen. For solar energy, emergency generators can be utilized if the amount of sunlight is not obtainable in sufficient amounts. Despite the fact that it can happen, it will not likely happen as long as there are people in power who don’t want to do it until it’s too late. If we continue to perform research on green energy, we will manage to find more sources and improve the existing technology.
Japan and Hawaii are using ocean thermal energy, which is power produced by harnessing different temperatures of the water. The methods of energy utilized in the United States is currently from only about 7% natural sources. While it has improved compared to eleven years ago, it could have been more if the price of fossil fuels did not decrease so much within the last ten years. At times the population is anxious and wants things to be done, and then other times seem to consider it is a big hoax.
You can find many natural sources for producing energy, such as the wind, water, solar, geothermal, bio-diesel and biomass. Once companies can find a way to profit from these sources as they can with oil, then you will find a big push for these green energy sources. If the oil supply all went away, the oil companies would almost certainly be rushing to one source or another to determine which ones they could profit on. The sad part is these companies are only looking to profit than to be excellent citizens of the earth.
