I guess being in Northwest North Dakota, I have a latitude bias. By winter, it will only be daylight from about 8:30 AM to 6 PM, in summer, dawn comes around 5 AM and dark as late as 11:30 PM. To me, changing the time change is just a pain in the hindparts, compounded by living in one time zone and (mostly) working in another.
I understand what you're saying, and I'm no enviro-wacko, but in all honesty setting clocks back is not much of a burden if it saves this much energy.
