How to counter-troll Greenpeacefags?

The last couple weeks, as I've been walking the eight blocks between buildings at work in DC, I've been approached by kids in blue T-shirts asking me to participate in a survey or whatever. Well, I just noticed last Friday that they were actually with Greenpeace.

How would you guys scare these kids straight before they get recruited for full-fledged eco-terror?

Wind power isn't quite that practical.  Can you command the wind to blow when demand spikes?

The biggest spikes in electricity demand in North America tend to be on hot humid summer days when there isn't much wind, so tens of millions of people go indoors and turn on the a/c simultaneously.

It's all very well to speak of putting batteries or gigantic capacitors underneath the turbines to store the juice in time of high winds to be metered out slowly when demand is high, but that also multiplies the construction costs severalfold--and the capacity of the batteries isn't infinite.

In a conventional power plant, it's a simple matter to crank up the output at need.  With wind, that's somewhere between difficult and impossible.
