... that he doesn't understand.
Do you honestly believe he doesn't understand it? No, no, he understands it perfectly well.
The problem is that there is sooooo much money and power available to him to continue trying to subvert the data.
Not to sound like too big of a pessimist, but none of these political games are going to change until renewable energy sources start challenging (or even beating) fossil fuels on economic viability and scale. And, knowing politicians and how they always try to make the situation seem rosier for "their side", then we'll be at the point where we start getting on to them for trying to subvert data on how much wildlife our renewable sources impact and the like. Obviously it would still be a net positive from a total environmental impact aspect to use renewables over fossil fuels, probably regardless of how many birds are killed by windmills and solar arrays, but the point is that once the money gets to be on the renewables side then the politicians will try to make renewables seem even better than they are.
