I hate these stupid work hours anyway that create this stupid habit of burning energy when it is not "naturally available". Couldn't changing the business hour according to the sun and wind be the real cost killer? No technologies, no investments involved, it just requires one smart boss, some smart accountant and employees. Imagine it: people would have no way to avoid raising their kids during the down season, we could fire teacher, single could do art, we could stop funding culture and it would be popular culture, maybe science, less working hours, but more people would have to work. It would solve quite a few problem.
