Unlike gasoline, where all prices are rolled into the one we pay at the pump, electricity prices involve a daily charge for the infrastructure to bring it to your building. This basic charge is the same, regardless of how much electricity is used. Then there is a rate in $\/kWh. A kWh is 0.0036 GJ.<\/p>\n<p>The author&#8217;s dwelling in Vancouver, B.C. is heated by natural gas, so electricity charges remain fairly constant all years around.
