Q. Dear Umbra,

How much does Fukushima (land loss, clean-up, rehousing people) add to the average cost of electricity (kWh) in Japan over the period they have not been running reactors? Compared to renewable, etc.?

A. Dearest Matthew,

Your letter made its way to my inbox before the latest concerns over leaks at Fukushima hit the news. I don’t know why you were sitting around of an August day wondering about utility rates in Japan, and I’m not exactly a deep expert on the subject, but I do enjoy the occasional break from lightbulbs and bug spray. Plus, I like your accent. So here we go.
