I highlight wind because the windmills have been a maintenance nightmare. On any given day at least a third will be nonoperational due to mechanical problems in some areas. Oh well, if we increase them by 700% we'll be in good shape...

When they do work, they are like a huge bird killer. They kill eagles, hawks, falcons which come looking for the dead ducks, geese, other waterfowl and just plain birds.
Many of the bird killer mills were put in migratory lanes that have been used by migratory birds forever. So ducks, geese and other migratory waterfowl fly into these windmills on their migrations. Then some just fly these areas to get to feeding areas and then fly back to the safety of a water area. If they do this twice a day, they have to run a gauntlet of rotating blades twice a day!
Besides the carnage of dead birds including some esa critters, a 6 to 10 pound Canadian Goose hitting one of the rotating blades at 50 mph will often knock that blade out of balance. This forces a shutdown of that windmill until the blade can be rebalanced or replaced. Some owners up here have just abandoned their windmills due to the high cost of bird damage to the blades of their windmills. A Golden Eagle or Bald Eagle will cause a lot damage to the blades!
Of course the enviralist pushing for the non power, ie, renewable power, will never get into the bird killing/slaughter aspect of these sometimes power producers.
