Well, like I said, after 40 years they should have bloody well come up with a few good ideas by now. In fact there were plenty of good ideas advanced 40 years ago, but nobody wanted to listen to them because they didn’t involve the World Bank making large loans.
Wind farms and the like are all well and good, but what about the rest of the planet where (contrary to left-wing opinion) a lot of pollution problems are festering? They can’t afford $1m a pop for wind turbines. The solution is not to give them $1m so they can buy a wind turbine (or a new Mercedes, as the case may be), but to get them doing other things that are cheap and will produce a large return on investment.
