At NRGwise we are big supporter of governement energy efficiency standards. Over the last 20 years a number of appliances (fridge, washing washer…) became regulated under stringent CA standards. Thanks to these, California is using almost the same amount of electricity than 20 years ago despite population growth.
Some appliances are still not regulated, like cable box. We had a few homeowners calling us over the years for unexplained high electricity bill, and the culprits were… the 3-5 cable boxes. If your TV is still running on this electricity guzzler model (see picture below), call Comcast for a replacement NOW! They have models available that are 5 times more efficient. See article here.
