Ecologists can reveal the frequency of bird and bat deaths in wind turbines, the traffic of birds around airports and the potential for distribution of disease and disease vectors.

Because of white nose syndrome, mounting public pressure and scrutiny from wildlife officials have become a major motivator for wind energy companies to figure out how to prevent bat deaths.

Ontario's Ministry of Natural Resources has set 10 bat deaths per turbine as the threshold at which the mortalities are considered significant and warrant action.

North American studies of bat deaths and wind turbines have found bats are killed either by being struck by turbine blades or by air pressure changes caused by the turbines that burst blood vessels in their lungs.

A recent National Wind Coordinating Committee (NWCC) review of peer - reviewed research found evidence of bird and bat deaths from collisions with wind turbines and due to changes in air pressure caused by the spinning turbines, as well as from habitat disruption.

Using this information, the Bats and Wind Energy Cooperative concluded that keeping wind turbines motionless during times of low wind speeds could reduce bat deaths by more than half without significantly affecting power production [6].

The good news, at least for now: No bat deaths have been attributed to the disease in Missouri, says bat biologist Tony Elliott with the state's Department of Conservation.

First, externality analyses posited by wind zealots never take into account the true environmental consequences of wind energy (rare earth impacts [see below], human health effects, bird and bat deaths, the CO2 generated from a two million pound concrete base, etc.).

Additionally, research into wildlife behavior and advances in wind turbine technology have helped to reduce bird and bat deaths.

Turbine - related bat deaths have been reported at each wind facility, and studies generally indicate lower bat fatality rates at facilities in the West than in the East.

Post-operation, the numbers of bat deaths and bird kills far exceed what was expected from the wind turbines, noise complaints are being made more frequently as a result of more powerful turbines, and wind power companies have abused their approvals by removing trees from protected woodlands, for example, or placing turbines on sites not consistent with the approvals.

* the amount of bird deaths, bat deaths and the small comparative amount of CO2 actually offset by the use of wind turbines does not make sense.

Impacts include bird and bat deaths and even noise pollution.

Until recently, there were three main issues regarding the possible downsides of wind power: bird and bat deaths, cost, and disrupting the appearance of natural landscapes.

Since the implementation of wind farms in the 1970s, opponents say that bird and bat deaths, as well as noise pollution, environmental damage and poor aesthetics are not worth the potential benefits.
