On the Fact that (According to Robert Bryce's Great Book, "Smaller Faster Lighter Denser Cheaper") Global Energy Consumption Has Been Growing by Approximately 450 Terawatt Hours per Year and for Wind Power Just to Keep Pace with this Growth (Never Mind Replace Our Existing Energy Sources), it Would Require 240,000 Square Kilometers of Land for New Wind Turbines EVERY YEAR

Of course one might say that we could conceivably reduce this growth through efficiency, etc. but being that most of the expansion is coming from countries like Pakistan, Thailand, Indonesia, and Vietnam (countries that are trying to escape poverty, in other words), that might not be at the top of their agenda quite yet.
