I work in the nuclear industry. I'm not directly involved in new build, but I have done projects for it, and will do in the future. I can assure you, nothing is going too slow.
Depends how you view "too slow".
I see oil prices increasing and battery electric cars gaining popularity.
I see stupid global targets on reducing CO2 meaning that building/using coal powerstations will become harder/more expensive.
I see China building
28 new nuclear reactors, which in total have 3x their current nuclear capacity.
I see our grid being already almost at the limit (weren't blackouts being predicted by 2012-2015?)
Now tell me, if by 2020 50% of the cars on the road are battery electric - will the current grid (minus any stations that are being closed) + the new nuclear builds be able to handle it? (hell, will the new powerstations even be operational by 2020?)
What about 75% of cars battery electric by 2020?
I do not think we are building enough in volume, and I think we are late to the game as it is (aren't some of the component suppliers booked with orders from China & India for the next 10 years?).
I
WANT to see us be in a position to be 80% nuclear by 2015-2020 (not happening as we are building too few and too late).
I want us to have a grid that can handle the volume it needs, plus allow us to experiment with new technologies and ideas that require plentiful energy
I want us to be actually leading research into next generation reactors (and building test reactors)
