I would agree with your points esnap and gtill, as to the weaknesses of how electricity is generated here. However the
Betterplace company specifically states having negotiated a contract with HECO to supply renewable energy in the amount necessary to charge their electric car batteries. In effect the batteries become the storage. So in theory the weak point of renewables (storage and excessive energy conversion steps) is largely bypassed . From the info I've seen, well to wheels efficiency of electric beats ICE everytime. Hawaii is a special case with its 3x price of electricity. Economically ICE probably beats Electric vehicles here in Hawaii if using the current oil fired grid power, but start throwing renewables on the grid in an amount close to your storage capacity in batteries and (I think) electric cars become the winner.
ESNAP: 5 MPG? C'mon. Even the heaviest ass electric car gets the equivalent of 50 mpg. See Neil Youngs electron guzzling Lincoln Continental.
