1) marginal (underutilized or unusable for area purposes) land available
2) land geography suitable to higher wind conditions
3) rural land available (further from town, fewer noise complaints possible)
4) transmission grid already in existence able to support/send large amount of power — as this is a big cost factor in a potential wind farm project, it must have made the town extremely attractive
5) land lease and tax monies going to struggling town making the local population likely to be very supportive

I’m a big booster of wind and I think it can easily produce 20-35% of an area’s electrical energy supply, more if cheap storage available. For most smaller communities, I think a smaller 1-5 turbine locally owned development would be best, but Goldendale’s a nice case to have a video about.
