That is the thing that gets me, people in the USA think 78 degrees during the daytime and evenings is too warm.Exactly. In Asia we ran our air conditioning at 26°C. We had fans running on the side. It was plenty comfortable. Fans make a big difference when used with A/C.
With that said, its not an excuse for the poor performance of the power companies, they should be able to deliver whatever power people want to buy.
