This was a theory not really backed by evidence. https://en.m.wikipedia.org/wiki/Daylight_saving_time https://en.m.wikipedia.org/wiki/Daylight_saving_time (Maybe a tiny electricity decrease and heating usage increase on average, depending on latitude - which would lead to more CO2 emissions overall, depending on the power source). I think the idea of "change time to save power" was a fine experiment, but it clearly failed to produce meaningful results so we can stop the experiment.

It is backed by numbers. Currently in France 17% of electricity consumption goes to lightning, including 12% for public lightning. It's moving down with newer lamps using less energy and other sectors using more. You have to think that daylight saving time was introduced almost a hundred years ago (heavily variable per region) when a significant amount of the electricity was going to (public) lightning, using lights available at the time that were very energy hungry and very inefficient. There was a reason it was done. Seriously, it was not a failed experiment carried out by idiots, like some commenters seem to think. Usage evolved and might have made DST worthless or counterproductive, if anything removing DST might show the importance of adjusting time to match energy consumption.
