My Planet.co.in: Some clever ways to save lots of electricity and money (and by the way: also the planet): "This web page concentrates on electricity use in households. It should, however, be noted that in moderate and cold climate zones, space heating takes up at least half of the overall energy use.

Therefore, proper insulation and ventilation is the first and most important energy saving measure. It can reduce heating needs to one-third (about 50 kWh heat/m2/y) or even one tenth (less than 15 kWh heat/m2/y) of what an average house would need. Remarkably, a properly insulated house, which only needs a third of the heat to keep you warm, will not be more expensive to build. The extra investments in insulation, ventilation and high-efficiency glazing, can be offset by a smaller and cheaper heating system. An efficient house will also be healthier and more comfortable to live in - it avoids 'cold radiation' (as from windows), the differences of temperature between heated and non-heated rooms is less, and it can be more efficiently ventilated.

In hot regions, energy use for active cooling (air conditioning) can be minimised or even avoided if the construction is well-thought out. In a moderated climate, active cooling can always be avoided"
