Greenes did huge damage to this country by instilling fear in nuclear power. While Greens mostly support good things to protect environment their opposition and fearmongering of nuclear plants caused us to build economy on oil.
Besides that we canceled all large-scale development of next generation reactors (breeders, lead-cooled, etc.) capable of burning 99% of fuel and leaving almost no waste.
On the bigger picture in the last twenty-thirty years people became more comfortable and lazy and unwilling to take any risks. This affected everything in the society - cancellation of Space Shuttle program, public safety even kids wearing helmets on the bicycles. If there is no risk there is no reward but it seems we kind of forgot about it.
