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, there are drawbacks, but none as bad as the possibility of running out of energy. Even if global warming isn’t really as bad as some state, using green energy sources is a good idea. The biggest gain to using green energy is that it is clean and doesn’t pollute the air with anything poisonous. Unlike fossil fuels such as oil, green energy is definitely renewable so we would never run out of it.
The cost of setting up green energy sources is very high but once it is up and running the maintenance cost is actually minimal. As for energy production, there is a possibility that the amount of energy being produced is not reliably established. Solar and wind energy can produce electrical power 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 decreased. A few green energy sources, like wave energy, require very precise conditions for it to be effective. It takes geologically unsound areas of the planet to be able to work with geothermal energy.
You can find tactics around most of the arguments against green energy sources, such as substituting one location for another. Wind turbines can be established 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 are available if the amount of sunlight is not accessible in sufficient amounts. You can find ways around nearly all arguments, but some people don’t want things to change, unless it becomes totally necessary. If we continue to perform research on green energy, we will be able to find more sources and improve the current technology.
Japan and Hawaii are using ocean thermal energy, which is power produced 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 greater 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 accomplished when there seems to be scarcity but change their minds when it improves.
You can find many natural sources for producing 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 by using 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 as well as 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.
