I believe one of the issues with wind and solar energy is that it is about 30 to 40 percent efficient at converting their energy to electricity. Oil and gas have much higher efficiency ratings. I'm sure we will continue to make progress in efficiency improvement for renewables as time goes by. In the mean time oil and gas will be number one if folks want to keep their standard of living the way it is. There are plenty of alternatives that I believe will some day take over and oil and gas will go by the way of the dinosaur. I have a hybrid pick up, great gas mileage and no worries about how far I have to travel. I think a good choice as we gradually go from oil to alternatives.
