As with most things done by Congress, Daylight Savings time has the opposite effect of the one intended.
“There is surprisingly little evidence that DST actually saves energy,” they state in the abstract to their draft paper. “Our main finding is that — contrary to the policy’s intent — DST increases residential electricity demand.”
Personally, I can’t stand the spring forward and would willingly forgo the fall back to not have to spend the time adjusting.

Congress needs some new ideas. What if it was just always 12:30? Think of all the energy we would save from clock batteries! Also, it would always conveniently be lunch time.
I am intrigued by your ideas and would like to subscribe to your newsletter.
