[tz] Saving electricity via horizontal time zones

A recent paper by Felix Weinhardt of the Spatial Economics Research Centre of the London School of Economics and Political Science argues that daylight saving time increases electricity use in the northern part of the U.S., but decreases its use in the south. Weinhardt proposes horizontal time zones to ameliorate this, and estimates that their use would save the U.S. about 0.1% of its total GDP. Weinhardt F.
