<prompt> Human: If anyone has some tips on how to save eletricity Id appreciate them! Currently in my household we use PCs a lot and it is what consumes more eletricity. I heard from someone that using eletricity during 12:00-06:00 is cheaper, is it true?  <response>: If your provider offers a time of use plan, then electricity could be cheaper at certain times of the day, but you would have to sign up for that plan specifically. Your PCs are probably not the largest consumers of electricity - things like heating, cooling, refrigeration, etc. are generally the large users. What do you keep your thermostat set to? Do you have LED bulbs? Do you turn offunplug items you arent using?
