Halting Swedish wind turbines at still summer nights would save almost all of the tens of thousands of bats killed by the rotating blades every year.

Every turbine kills 10-15 bats annually on average as the creatures are struck when they hunt insects attracted by the spinning unit, according to a study by Sweden’s Energy and Environmental Protection agencies. Halting turbines on summer nights when winds are low would save most of the bats without a significant loss in renewable generation.
