Green Energy Sources Do Have Several Disadvantages

By Josephine Graham


When you have to make a crucial decision, you need to evaluate the advantages along with the disadvantages. In the case of Green Energy Sources, you'll discover some disadvantages but it is nothing compared to the inevitability connected with no fossil fuels. Whether or not there is actually global warming, we should not shun the idea of using green energy sources. Green energy is actually great regardless of our present state because it does not release any toxins into the air and it's clean. Green energy is additionally a renewable resource so we could never run out of it such as fossil fuels.

The cost of setting up green energy sources is very high but once it is up and running the maintenance cost is usually minimal. Additional complications can be the regularity of such power. Solar and also wind can both create electricity, but the sun doesn't always shine and the wind doesn't constantly blow. Some believe that building wind turbines will cause the amount of farmland to be reduced. A few green energy sources, like wave energy, require very precise conditions for it to be effective. Furthermore, geothermal energy can only be set up in areas that have some kind of volcanic activity.

While in some cases, setting up green energy might seem impractical, there are ways around it to make it occur anyway. Wind turbines can be set up near the coast 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 however we can correctly assume changes will happen. For example, when using solar energy, excess energy is stored as back up in case there are days when there is not enough light to generate enough electricity. You can find ways around the majority of arguments, but some people don't want things to change, unless it becomes totally necessary. Exploration continues to go on to locate sources that will function better, so that we always have the power that is needed.

Japan and Hawaii are applying ocean thermal energy, and that is power generated by harnessing different temperatures of the water. The methods of energy employed in the United States is currently from only about 7% natural sources. It was larger than that 11 years ago, but the concern pertaining to running out of energy would seem to go up and down. When things appear dire, people want to look for alternatives but once things settle, everything goes back to the status quo.

You can find many natural sources for creating energy, such as the wind, water, solar, geothermal, bio-diesel and biomass. If there was as much money to be made harnessing these kinds of energy sources as there is with oil, they would probably be available for everyone. If the oil supply all went away, the oil companies would almost certainly be rushing to one source or perhaps another to determine which ones they could profit on. The sad part is these companies are just looking to profit than to be good citizens of the earth.
