Bhairitu: > Does save any energy either, in fact it increases > energy consumption... > Daylight Savings Time (DST) means that we temporarily move our clock's hands forward during the summer and back in the winter. That's because we want afternoons to have more daylight and the mornings to have less.
That way, we save energy because residential lighting use is less. By setting back the time of sunset and sunrise we can use less energy from light bulbs in the evenning. It's that simple.
