Millions ??? Do wind energy generators have a sonar/ radar blocking system so good that every bay within 20 miles head straight for the blades

Not quite sure what you are getting at? Bats do seem to be attracted to turbines. Not all of them of course. Enough that it is causing significant population problems. The current estimate for US/Canada is about 1million bats per year dying at wind turbines - a large % are migratory bats.

How many turbines are in America

I don't know that number, but NASBR just released a revised position statement on wind energy with summaries for CAN/USA of fatalities described by MW

I think the last estimate I heard for Alberta was about 1,000? But I am not at all confident about that number.

Understand that in terms of bat fatalities - it can vary wildly. Bigger, taller turbines kill more bats. Turbines near rivers & migratory corridors kill more bats. Some turbines are not killing bats. We just don't have a good handle on migratory corridors. It's a research priority for us this yr.

The SMRT curtailment system has limits - it detects bats echolocating (hopefully before they are within range of the rotors). But bat detectors do not have a long-range of detection. This is a good paper on SMRT curtailment

For more information on bats and wind energy - we have a nice summary on our website and a table with several key papers that are linked for download.
