Talking about a waste of good energy. I was walking past a Tesco filling station building recently on a hot day. As I walked past some ground situated external air con units I felt a warm breeze blowing blown at my legs. That was waste heat being sent to the outside air of the building. In this day and age could it not be stored somewhere to heat water or the building on cooler days rather than just going to waste?
This example must be repeated millions of times across the whole country.
