Also, wind and solar power is a clean source of energy that does not pollute the air. Most Americans live in areas of poor air quality. This affects the health of American Citizens and is a major cause of asthma in children. This is not only an economic issue, but an ethical one as well. The government should be concerned for the health, safety, and welfare of American citizens on this one, not just the potential economic gains.

Sorry, I only meant that geothermal is not sustainable, not wind or solar power. Unfortunately, neither wind nor solar power is capable of meeting our energy demands. The figures I've read is that even with substantial improvement in solar and wind technology, including bladeless turbines, at best we may get to somewhere between 10-15 percent. Conservation will help substantially. But we are still way short.
Nuclear is an option. It's clean, realitively cheap by today's standards, and is probably fairly safe given recent technology. Waste is the problem, although the decommissioning of nuclear weapons has advanced the state of the art in dealing with nuclear waste tremendously. But we are still 100 years away, if not more.
Delts also raised a good point...even if we left fossil-fuel energy behind, we still need lubricants, polymers, other plastics, composites, and on and on, which need oil of some form or description.
So I agree with you--I wish we could avoid fossil fuels. But it is not going to happen for at least another 100 years. Our best hope is to mitigate the environmental impact of the developments as much as possible and to invest the proceeds wisely for future generations.
