Bats killed by wind turbines

One of the potential conflicts between the generation of 'clean' energy and wildlife conservation is the danger wind farms are presenting to bats. Apparently the risk to bird populations has been overstated, but in some areas many bat deaths have been reported.

For example, nearly 3,000 bats were killed in a six-week period at one wind farm in the USA, and nearly 1,700 were killed over a same period of time at another wind farm.

Now researchers at Aberdeen University believe radar may be key.
They studied the behaviour of bats at radar installations and found they did not forage where electromagnetic radiation could be measured. This presents the possibility of electromagnetic devices being used at wind farms to keep bats away.

There is more on this topic here.
