The next problem is that you have mixed two different complaints making neither one correct. Either individual windmills cost the same as nukes and produce less power or a billion watts worth of windmills produce 1/100th to 1000th as much power. Neither of which is true. Not only not true but seriesly totally way off the mark.
In other words a either a 1 mw wind turbine costs the same as a 1 gw nuke plant or 1 billion watts worth of wind turbines produces 1/1000th as much power as a 1 billion watt nuke. This is the charge you have made and neither is correct.
No 1 windfarm (with thousands of turbines) makes megawatts but costs the same as a nuke plant that makes gigawatts. Which is the simple truth and is why windfarms are not ready for primetime.
