From what I’ve read the Volt definitely isn’t a cold weather vehicle, the heater doesn’t seem to be too efficient. You could wear fur but then PETA would be protesting you. :)
When I was looking into ways to heat my shed, I quickly learned electricity is not a very efficient or cheap way to produce heat. Safe yes, but it really chews up power.
The beauty of burning gasoline is that you get heat for free.
