I respect this initiative and participated, to a great extent (Left the fridge on), last year. It's good to raise awareness.

But this year, I’m revisiting the purpose of conserving energy for an hour, then resuming unfriendly environment habits throughout the year.

I'm not sure how the benefits are measured and how much power is being saved on that day, at each country’s local time.

Also, suppose a whole country, even a city or a small town switched off lights, and turned them back on almost simultaneously, would that affect circuits or cause any shortage somehow?

Many questions?

Salam
