The old series or the the movie with Nicole (I wish I was from down under) Kidman?
The Lakota turbine by Aeromax is approximately 7 feet (2 m) in diameter and produces 900 watts of three phase power. It uses a three phase rectifier and charge controller so that it is free to spin at whatever speed is optimal for a given wind condition. Lightweight materials (the entire turbine weighs only 16kg (35 pounds)) allow it to respond quickly to the gusts of wind typical of urban settings. It attaches to a size 9 structural pipe (similar to a TV antenna mast). The Lakota is very quiet. Even when standing up on the roof right next to the mast it is inaudible. Climbing up the mast, it is still inaudible from just a few feet under the turbine. A dynamic braking system regulates the speed by dumping excess energy, so that the turbine continues to produce electricity even in high winds. The dynamic braking resistor may be installed inside the building, so that the 'heat loss' will heat the inside of the building (i.e. during high winds when more heat is lost by the building, more heat is also produced by the braking resistor). The proximal location makes low voltage (12 volt, or the like) energy distribution practical, e.g. in a typical installation the braking resistor can be located just inside to where the mast is attached to the building. Such small-scale renewable energy sources also impart a beneficial psychological effect on building owners, so that they begin to take on a keen awareness of electricity consumption, possibly reducing their consumption down to the average level that the turbine can produce.

If insulation were perfect (I know it cant be, we have to breath after all) then once set at a temperature it would remain forever. Of course this cannot be achieved, but with good insulation very low heating and cooling requirements can be achieved.
So the reality is we have to replace the losses
