We have the knowledge. We have the technology. What we lack is a government who seems capable of devising , supporting, and implementing a plan to free us from our dependence on foreign oil. American's also on the other hand seem to have a very short attention span. Our economy is going down the tubes and fast. This isn't the first time, we have been there before. Our memory seems to blot that all out when fuel prices drop we waste no time wasting, producing, buying and using cars that get low mpg etc. Only when it truly hurts us in the pocketbook do we suddenly switch into our conservation mode. We need to be in this for the long haul, permanently and totally. We need to elect a president who will commit to rapid deployment of a plan of energy independence. We need to use every resource available to us to reduce consumption of fossil fuels. We need to take full advantage of natural energy sources such as wind power and solar power. We need to use our technological knowledge of hybrid cars, v2g technologies etc. They all play a vital role in reducing our dependence on foreign oil and improving our environment not to mention relieving our suffering economy.

Lets face the reality -the US has used oil and coal for along time-for over 20 years we have known how harmful it has been on the environment - but the government and big business did not care as long as there were good size profits to be made. And the every day working person has so much to deal with -just trying to earn a living -and "get ahead". The science of carbon based energy and the harmful effects is basically very simple -even middle school science fare students can prove it .
So it all comes down to profit when heads of state are concerned -and how much will something cost on the other end.
Wind and solar energy will be virtually free once the investments are made -low maintenance - And I for one am sick of paying high home heating bills etc sacrificing other important purchases such as health insurance and better quality food and -perhaps new clothes -you name it -with these high energy prices for get about purchasing luxury items.
So carbon based energy -is harmful - expensive and any one who thinks that it is OK to use is just not willing to be educated on the subject and closed minded.
