It's a shame environmentalist still equals environmental whacko in some folks' minds. Just as I'd hope we all want to find cleaner, renewable forms of energy (vs. polluting, non-renewable forms), I hope we'd all want to do that with considerable thought and care. I don't think there's anything wrong with due diligence, and it sounds like the farm is fully slated to be up and running in 5 years or so. To me, it doesn't sound like other than expressing concern for migratory bird species (we are on the Central Flyway, afterall) any environmentalists or environmental groups have stepped in and become a thorn in the side of wind farm.
The Cape Cod wind farms appears to be up in the air due to a lawsuit, not from environmentalists so much as property owners who don't want to look at wind turbines, apparently. Not sure what their real estate costs are up there, but hard to blame them, given how much uproar one Walmart creates in various towns.
