If you take solar, which is eight and 10 [on the list], and wind, which is two and 22, and you combine them, they are definitely near the top. But you can’t model on- and off-shore wind the same, because the economics are vastly different. And you can’t model rooftop and solar farms in the same model. So in some cases we broke things up that people think of as aggregated.
But even then, the number one solution is educating girls and family planning.

How do you put numbers on that?
Paul Hawken
We took the numbers from other agencies — from World Bank, WHO, IPCC. What they are is the delta between the median high population projections of the UN in 2050 and that reduction alone. There are so many ancillary benefits and impacts of 1.1 billion less people, though.
