How do people drink hot drinks in this heat?

We can't be relying on aircon in a world that is choking itself from electricity consumption because we can't produce enough cleanly. Plus people need to save their money for winter fuels costs. We need to get thinking properly about how we live in order to cope with rising heat. Such as when we get to certain high temperatures, we have laws that state a workplace can't force you to wear a suit or formal attire, instead you have the right to wear something cooler . Or any business that can have its workers work from home has to do that by law in hot weather because it is easier for people to keep cool in individual homes instead of crowded into bodyheat-heated offices with a million computers heating the space. For people at home they need to think of changing up their daily routine to match the heat patterns- housework and jobs in the cool of the morning, don't go out in the heat of the day, stay downstairs where it's cooler, sleep with windows open (not everyone does as some people like my dad where always convinced a burglar could sneak in through a 6 inch transom window when there was  a ten foot drop on the other side and nothing to stand on)  Don't stay in rooms that are faceing the sun, move to cooler ones if possible as the sun pans round... There are plenty of daily behaviours and things that we could change to make it easier to cope without AC. But I really don't think we should be padding out Britain with them in the future, because we can't support that amount with clean, non nuclear energy. We've already got part of society thinking that electric cars are he answer to fuel consumption, but we can't even fuel entire cities' daily needs with renewable energy, so god knows how we could add a population of electric cars and AC to the demands...
