 It's cheaper to do it this way because the power that I'm using now is five times less expensive than the power that will be at 2 o'clock. It's time of use with utilities. So I'm the delivery driver that understands the importance of doing the majority of my driving when gas is $1 a gallon. I'm getting all the heat out of my house for five times less money than it will cost me at 2 p.m.
