Is it wasteful to leave the lights on if (and while) you heat with electricity? I mean, the heat of the lights is used to heat the house and as a result the eletric heaters have to heat less. Does it even out? Which kind of light bulb is the more efficient heater: CFL or incandescent? Is it more wasteful to leave CFLs burning or incandescent lights?
