We like windmills. Really? What about the dead birds? Try going to the bottom of a windmill some day. Not a pretty sight.
Vast fields of solar panels, fool birds into landing by confusing them into thinking that the solar panels are a large body of water. The birds desperately need water, and when and where there is none, they (then) lack the strength to leave the ground to seek water elsewhere, and often perish in great numbers.
