All right, let's talk two different things at this point relating to the world of Fallout and wind energy.
First of all, let's talk about the War itself. Not a lot of information on the actual conduct of the war exists outside of interviews with the Enclave in Fallout 2. The only thing we can know for relative certain is that the Chinese launched their missiles first. Based on the evidence collected from Fallout 3's various computers within the Pentagon and the other government installations in DC, we also know about the relative success of the war against China prior to the launch of nukes. We know that the Chinese were on the run in their own homeland, and that US troops had even launched full campaigns in the Gobi Desert and the Yangtze (based off of evidence from New Vegas). Therefore it is logical to assume that at the time of the nuclear holocaust, the United States was not far from breaking the Chinese, thus the probable reason for launch.
Now, based on the areas of destruction in the first three fallouts, and evidence from conversation with Mr. House in New Vegas, I think I can make some reasonable assumptions about Chinese "strategy" in nuclear war. Though it may seem to have been indescriminate nuclear carpet bombing of the United States, I think it may have been more complicated than just that. Mr. House states that the area covered by Fallout: New Vegas was targetted by 77 nuclear warheads and that only 5 got through. Therefore I believe that judging by the areas we know were actually hit by bombs (i.e. Nellis) we can assume some of the Chinese's targetting priorities. Here is the assumptions I am making based on Fallout games to gauge where Chinese bombs hit:
1. Military bases and outposts: A caveat on this. I'm assuming that Air Force Bases would receive the highest priority of these, and training centers and National Guard the lowest. The West Coast would likely also receive the worst devastation against their bases due to the proximity to China itself.
2. Symbolic Targets: While not exactly rational, it seems that the Chinese placed a major emphasis on trying to hit symbolic American targets. Evidence of this seems to be the high concentration of missiles towards the trip and the obvious dead-on strike against the White House.
3. Energy Plants: this does not come from any evidence within the actual Fallout games, and in fact I'm astonished that none of the 5 that got through in New Vegas managed to hit the Hoover Dam. Considering the obviously large number of nukes the Chinese possessed and the equally obvious lack of any defense by the Americans (which I find a tad unrealistic, though it makes more sense if you consider the Enclave WANTED nuclear war to wipe the slate clean) I think that it's likely that electric facilities like hydroelectric dams, wind farms, and nuclear power plants would all rate highly on the Chinese targeting. Therefore, as previously stated, power plants are virtually impossible to find throughout the wasteland.
4. Now, based on what I know of about the Cold War and US/USSR tactics for a proposed nuclear war, I believe a priority target for "dirty bombs" would be regions that were known for agriculture. Therefore, prewar breadbaskets would likely have been irradiated to make them useless to the Americans and thus starve them into surrender.
5. Last priority target would likely be population centers. Surprisingly, based on evidence from all the Fallout games, a large amount of people "survived" the initial bomb drops. Though the majority of these turned into ghouls, it's my belief that the Chinese hoped to wipe out the resources of the US, and then let the population rebel or otherwise eliminate itself. A vicious strategy when you think about it.
All right, moving on to the issues about wind farms and energy. The reactors currently found by the Appalachian Commonwealth, Fort Morgan, and the Brunswick Nation are considered to me to be "mini" reactors. What this essentially means is that while they could power a medium to large compound of buildings, they are certainly not on the scale of vast city-supplying power. Also, I will admit that wind farms do seem to be present in the Fallout game, as I just recently stumbled into one in New Vegas populated by cazadors. At this time though, I'm choosing NOT to include them because they are still a relatively advanced piece of tech for balancing and electricity. If I were ya'll I'd look into the other, more immediately practical, properties of windmills. When you get right down to it energy really isn't that essential at this stage in the game unless you REALLY want robots. The only other purpose is for activating goodies or projects, which I believe the majority of you don't have. Fortunately, that's why I added the conversion of tech parts into energy.
About converting into energy. The assumption is that you find working pieces of old technology and strip them down for their batteries. While this sacrifices the technology at hand, it does provide the power you need for the minor jumpstart of a device or robot. I think it's suitably realistic for the situation.
