Not impressed they should make it Nuclear powered. Then again its M$ so....
Nuclear fission is expensive to build, expensive to maintain (safely), involves loads of red tape (and therefore takes a long time/plenty of effort to plan, get permission, etc.), takes a long time to build, faults require a greater downtime to fix (unless you cut corners...)...
Wind turbines have their flaws too, sure, but there's less resistance to them, you can start getting power pretty much as soon as you erect the first tower, when one starts having issues it's the only one you have to shut down...
