Hmm, a pretty stupid test. Left out alot of things, also didnīt really rely on which power sources you use, the assests close to home, and such things.
They also said that "you do this" withouth even arguing or even taking consideration to anything or giving you any options. Sweden donīt use fossil fuels to that extent for instance, and we have alot of arcres for every person here..
Well, seems like a nice propaganda to get a book sold or read!
