every computer should have power saving turned on
mine do and its cool that i can leave them on all the time using only a couple of watts of power and have them be back for use in just a couple of seconds
new laptop cpus throttle the cpu speed to save power, i think desktop cpus should as well.
of course i think every state in the us it is practical and other countries as well should have wind and water power. ny state produces quite a bit of wind power and several rivers, biggest being the niagra, produce electricity as well. the more power we produce cleanly the more our green appliances will help.
