I learned this the expensive, hard way. I had a studio in Paris that only had electric heat. 2 months after it started getting really cold I got the electric bill, $250. After that I shut off the heater at the breaker, bought a portable heater and a jug (20L) of kerosene for $80. That jug lasted 2 winters.
