For a fraction of a fraction of a fraction of a fraction of our energy: wind power!

At 20% "penetration," a typical goal (limited by the amount of excess capacity on the system that is free to balance the fluctuating wind load), wind energy would in theory replace only one forty-fifth of our energy.

Electricity accounts for roughly a third of all energy use, 20% wind would be a fifth of that third. (And that fifth requires four times the capacity of that actual output.) And the effective capacity (because of its variability) is yet a third of that output.

Even in theory, then, it is clearly an awfully destructive and expensive "alternative." In reality, it is even worse.
