Actually, the technology has improved significantly over the last 15 years.
Taken from Lester Brown's Plan B 2.0: Rescuing a Planet Under Stress and a Civilization in Trouble:
One of wind’s great appeals is its abundance. When the U.S. Department of Energy released its first wind resource inventory in 1991, it noted that three wind-rich states—North Dakota, Kansas, and Texas—had enough harnessable wind energy to satisfy national electricity needs. Those who had thought of wind as a marginal source of energy obviously were surprised by this finding. 19
In retrospect, we now know that this was a gross underestimate of the wind potential because it was based on the technologies of 1991. Advances in wind turbine design since then enable turbines to operate at lower wind speeds, to convert wind into electricity more efficiently, and to harness a much larger wind regime. In 1991, wind turbines may have averaged scarcely 40 meters in height. Today, new turbines are 100 meters tall, perhaps tripling the harvestable wind. We now know that the United States has enough harnessable wind energy to meet not only national electricity needs, but national energy needs. 20

I think that wind is probably the best viable option we have at present. Theoretically, wind could provide enough electricity to satisfy our current stationary energy needs, and in addition, to recharge fuel cells to run our vehicles. Call me a treehugger, but I envision a day (though probably not in my lifetime) when people will look back and say, "Gee, they actually had to burn stuff to create power!? How primitive!"
