Nuclear's big win over wind (and solar and wave and tide and hydro and...) is it's density. The _little_ reactor at Fukushima daiichi is ~500MW. The other 5 are closer to 1GW. Big wind turbines (at least here in .au) are rated at ~2MW peak, but with 15-30% utilization (the wind doesn't always blow at just the right speed to provide the amount of power you're using). That means the littlest reactor at Fukushima daiichi would need about 1000-1500 large wind turbines to replace it, and the 10 reactors in the two Fukushima complexes would need 20,000 or 30,000 400 foot diameter turbines on 250 foot tall pylons. That needs a _lot_ of space. Putting them off shore increases the maintenance requirements and the difficulty of getting to them means the increased maintenance is also more expensive.

I really like wind power. I think wind farms look beautiful. But they aren't capable of supplying anything like as much power as we need.
