I'm luke-warm on electric cars at best. For example the Tesla might do 356 Wh/mi. That's 1.3 megajoules of energy per mile. A litre of diesel has ~32 MJ and will get you some 11 miles, so 2.9 MJ per mile. Makes the electric look efficient? However, remember that to generate the 1.3 MJ of electricit...

I wonder whether, rather than Oklahomans building ultra-reinforced buildings, they instead always build basements and build any above-ground floors to be of lightweight timber (suitably insulated) that can be re-built more cheaply. Roofs could be lightweight - maybe lots of green roofs.
