Early in their development, long-bladed wind turbines were seen as threats to birds, especially migrating varieties used to crossing certain mountain passes. Now, in spite of technological improvements and efforts to keep their propellers off at critical times, lawsuits are descending on wind farms - working ones and some on the drawing boards - to turn them off or to stop development in the path of some birds' migration and in bat habitat. But behind some environmentalist arguments against the increasing clusters of wind turbines is a more basic, if less compelling objection: They're ugly. They can be noisy. Besides that, opponents wonder, how do we know they're not sending surges of electricity into the atmosphere, doing who-knows-what damage to animals, two- and four-legged alike?

What this will take is an Apollo-like program focused on new technologies and renewable energy resources.
