Understanding Wind Turbines and Heating/Cooling: “Eureka!”

May 2nd, 2012 | by Breath on the Wind

Are wind turbines that produce electricity "bad" and contributing to global warming or is it all just hot air? (Hint: the answer has something to do with the air, but not the global climate.) Our world is warming. Just a little, but it is enough to cause considerable and catastrophic climate changes. We know that for anything to warm there must be a source of energy. Wind turbines produce electricity. That is energy. Couldn't that be a source? Archimedes solved one problem by jumping out of a bath and running through the streets naked, exclaiming "Eureka!" ("I have found it" in ancient Greek). We can also understand the wind turbine effect by thinking of being naked in a bath.
