People get excited about the birds and bats killed by 400-foot windmills planted in their flyways, but the average wind speed should also be considered. In our region, the wind speed averages 11 to 12 miles per hour, but the windmills are most efficient where winds are 30 mph. Unfortunately, many regions with good wind speeds don’t have the infrastructure to transport electricity, and the wind-factory people don’t want to cut their profits to build them. It seems a shame to lose good agricultural land to a second-rate energy system.
