 as hard as you want that's a brand new thing power companies are quote messing with your thermostat remotely if you have any smart ones and if you have them registered some states even give you some sort of discount when you let them know you have them so apparently more and more people are walking home and saying wait a minute i left the house and the thermostat was set at this temperature and now all of a sudden it's basically 100 degrees in my home because somebody turned it off and that somebody might be well not somebody in the house i thought that was really interesting
