With most things, you are told to weigh the benefits against the disadvantages, and take the data 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. Whether or not there is really global warming, we should definitely not shun the idea of employing green energy sources. You would like to use green energy because they are generally clean and do not send anything dangerous into the air. In contrast to fossil fuels like oil, green energy is renewable so we would never run out of it.
The hardest factor about green energy, is that the original start up cost is really quite expensive, but after that, it doesn't take nearly as much to continue to operate it. As for energy creation, there is a likelihood that the amount of energy being produced is not reliably fixed. While solar and wind power can produce electricity, if there are times of cloudy days or there is no wind, these sources may not be able to generate enough power. There are some people who are concerned that building wind turbines will certainly cut back on the amount of farmland available. Other types 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 possible to setup a geothermal energy.
There are approaches around most of the arguments against green energy sources, for example substituting one location for another. If space is necessary, wind turbines can be built near the ocean where wind is definitely much more steady. Changes in the weather are unpredictable however we can safely assume changes will happen. For example, when using solar energy, extra energy is stored as back up in case there are days when there is not enough light to create enough electricity. You can find ways around most arguments, but some people don't want things to change, unless it becomes completely necessary. Research continues to go on to find sources that will function better, so that we always have the power that is needed.

Ocean thermal energy is being tested in Japan and Hawaii where by harnessing the changing temperatures with the ocean, electricity is generated. Only about 7% of the electricity in the United States is from green energy resources. This proportion is greater than it was eleven years ago but it hasn't widened much since fossil fuel prices fluctuated. Society has a way of seeking things to get accomplished when there seems to be scarcity but change their minds as soon as it improves.
There are many selections for green energy including bio-diesel, biomass, geothermal, wind, water and solar. If there was as much money to be made harnessing these types of energy sources as there is using oil, they would probably be available for everyone. If the oil supply all went away, the oil companies would more than likely be rushing to one source or perhaps another to find out which ones they could profit on. Unfortunately, the only point that drives most companies is only how much money it will make.
