The entire project has at least as large a carbon footprint as nuclear. It's like the Tesla and other hybrid or electric cars; sure they make the owner feel like they are helping the planet and saving money, but in reality they are spending more and the processes for creating that vehicle are at least as contaminated if not more so than those for creating gas powered vehicles. But I get the sentiment, it's just we aren't children so feeling better about ourselves shouldn't be the goal but it's a very marketable emotion and folks fall for it.
Would you want to live near a nuclear power plant?
