This speaks for itself. To say nothing of the cost of painting all the roofs in the world white (upwards of $30 a gallon for paint) it stands to reason that making all that paint would involve processes that produce significant 'carbon usage' and would probably greatly offset any actual benefit, even assuming that the good doctor is right about global warming in the first place. What's more disturbing is that this is the conversation you get with the country's leading government official on energy policy. Not environmental issues but energy policy. He claims that white roofs will cut consumption. I claim that he's got needs that the other kids don't.
I'm interested in any cheaper and less ridiculous options from my homeowner friends. Drop me a comment with ideas you have to reduce home energy consumption that aren't idiotic. I'll start.
