"At the time the Danes decided to back wind power, the cost of electricity produced this way was many times greater than that produced by fossil fuels. The Danish government, however, could see its potential and supported the industry until costs came down. Today Denmark leads the world in both wind power production and the building of turbines; and wind now supplies 21 percent of the country’s electricity. One striking aspect of the way that wind power has developed there is that some 85 percent of the capacity is owned by individuals or wind cooperatives, and so power lies in the hands of the people."

"Some time this century, the day will arrive when the human influence on the climate will overwhelm all natural factors."

"I don't know, man; don't worry about it."

"Crikey means gee whiz, wow!"

"Crikey, mate. You're far safer dealing with crocodiles and western diamondback rattlesnakes than the executives and the producers and all those sharks in the big MGM building."

And I went, "Not really." And he said, "Do you watch any of them?" And I said, "Yeah, a couple." And he said, "Why do you watch?" I said, "To see what you're gonna do wrong." He said, "Gotcha! The moment I've got you whipped in to see whether I'm gonna do anything wrong, I can tell you anything. And you're gonna remember it.""
