Scott Adams has an interesting blog where he tries to reason his way through some of the issues of the day (a bit more seriously than in his cartoons). He has been blogging about all of the decisions associated with building his new house, and one of the big decisions is whether or not to use solar power.

Here is a post where he recognizes that the usual analysis (decision) about solar is just a choice of yes or no. This sounds okay, because you’re in the middle of building the house and have to make a decision, right?

Well, there’s another branch that people often overlook – wait and retrofit solar later. Nice observation, especially since that branch may be the best one.

I also can’t help but smile when I read the summary:

My new home will have solar power. It was a city requirement. I plan to brag about it to people who are passionate about the environment and bad at math.
