Compared to coal, nuclear power is actually much safer. As a populace, though, we just understand coal better (and we haven’t been made to fear it). I think the move to nuclear power would benefit this country (while, of course, we always strive towards cleaner, renewable energy).
Unfortunately, our government kowtows to the dirty energy interests. And judging from their antics as of the last 30 years or so, I doubt real policy change is going to happen in my lifetime.
