Energy conservation

I read somewhere that Ontario Hydro has a new scheme to reduce energy consumption by 10%. The intent is to reduce the frequency of all the power in the province from 60 cycle to 54 cycle, 10% less. That's still within the tolerance of all the motors and lights and various power supplies so all will still work fine.
It means they can slow all the generators down that little bit and save on the energy needed to turn them - a brilliant idea. I think they're starting the first trial this spring in Ottawa, just in time to be ready for those summer brownouts we all dread.
