25% Efficient is bad? (Score 1)

I'll be the first to say that I don't know the efficiency ratings of most modern power plants, but I can say that when I was in the Navy we did calculations of how efficient our nuclear reactors were and while I'm not going to say what the number was, I will say it was significantly lower then the 25%. Granted our systems were closed-loop reactors instead of the open-loops (more efficient, but also dirtier) reactors that are usually used in commercial systems, but it still doesn't seem that 25% is all that bad in the scheme of things.
