Also, the fact remains, more birds die from collisions with tall buildings, windows, cars and power
lines than wind turbines.

The bottom
line is that these ghastly
wind turbines consume more energy in their construction, maintenance, back - up requirements, and ultimate decommissioning
than they can ever produce in their lifetimes.
Kristie, if you think this is the main cause of bird deaths you must also do some research in power -
lines, skyscrapers and coal power - plants which on average kill more birds
than the
wind turbines
Skyscrapers, power transmission
lines, vehicles and other existing human artifacts / activities are much more lethal to birds
than are
wind turbines — at least, since small
turbines sited on migration routes have become a thing of the past.
Elsewhere, they note, «if society aims to increase output of (say)
wind energy with the least energetic investment, it is better in many cases to just build another
wind turbine, or possibly transmission
lines,
than to build a battery to store power that arrives at off - peak times.»
By calculating the EROI of all the options, researchers have found that it can often be better to simply build more
wind turbines or solar panels, or even transmission
line to move power from somewhere where the sun is shining or the
wind is blowing to somewhere where they're not,
than to build storage.
