A watt costs a watt, regardless of what's plugged in. That watt (or killowatts) is expensive and is indexed directly to the cost of gas, oil, and coal. The scarier part is that gasoline is a consumer chosen fungible commodity at the point of purchase, driving competition. You have to plug in the family chariots and those go into a monopolized utility grid.
Bend over Bubba cause it's coming good and hard.
