last month when we did not have water and were not heating the house or heating with electricity the weather was not too cold. Few days ago here we had a bit of snow, yesterday it was raining very heavily. But the temperature is still nice. +6 today. +8 a day after tomorrow. It seems to be warmer than usual. I don't mind that-perhaps we will save on heating cost.
Oh yeah, for those in places where the temperature goes very low having it a little warmer can be a good thing, save on heating costs as you say. Conversely, here when it's super hot we run our air conditioners and up goes our power bills. I have a solar system though so am able to save a fair amount on electricity costs.
