No less than the scientists at the National Academies of Science and Engineering state that because renewables are intermittent, and can't be counted on; that is we don't have a "throttle" on Mother Nature to tell her what our energy demand is; renewables can be at MOST 20% of our electric power mix. They have stated this in numerous energy studies conducted over the last few decades, the most recent published in 2009.
Nobody is forgetting about the waste. The USA wouldn't have a waste problem if we reprocessed and recycled our spent fuel the way other countries like France do. Here's an excerpt from a Frontline program that has an interview with nuclear physicist Dr. Charles Till, who was at the time Associate Director of Argonne National Laboratory:

Q: And you repeat the process.
A: Eventually, what happens is that you wind up with only fission products, that the waste is only fission products that have, most have lives of hours, days, months, some a few tens of years. There are a few very long-lived ones that are not very radioactive.
If you reprocess / recycle; then you DO NOT HAVE long lived isotopes; namely the actinides; in your waste stream. GONE is the multi-thousand year "problem" of nuclear waste. You have only fission product waste that have the MUCH SHORTER lifetimes that Dr. Till cites.
Scientist know the limits on renewables; and scientists say our only real solution is nuclear power.
