Where did you get this "5000 billion kilowatts" from?
That's 5 million gigawatts, and would require 5 million reactors if they are one gigawatt each.

Current global energy use is around 15 terawatts,
which is 15 thousand gigawatts or 15 billion kilowatts.
That's only going to increase 50% by 2030.

Here's the projections by the EIA:

We can reduce fossil fuels by increasing efficiency and renewables.
There are many factors which will prevent nuclear from increasing faster.
McCain wanted to build 45 reactors by 2030, that was impossible:

Christie Todd Whitman: McCain's grand vision is a "nice idea" but it's "not going to happen"

"I'm not quite sure the number McCain put out is obtainable," says Adrian Heymer, senior director for new plant deployment at the Nuclear Energy Institute.

The people doing PR for the nuclear industry said that even if pro-nuclear McCain was elected we wouldn't have 45 new reactors in 2030. So forget about the nuclear hype. No major environmental organization has endorsed nuclear energy as a solution to climate change - it's too expensive, takes too long to build, and has many other problems. The alternatives are more cost-effective and faster to implement.
