According to Energy Star, electronic devices (TVs, computers, etc) only account for about 4% of home energy consumption, so I'd doubt that device usage patterns is much of a driving factor here. Almost three quarters of our home energy is spent heating things up or cooling things down: Heating: 29%, Cooling: 17%, Water heating: 14%, Appliances: 13%, Lighting: 12%, Electronics: 4% Source: http://www.energystar.gov/index.cfm?c=products.pr_save_energy_at_home http://www.energystar.gov/index.cfm?c=products.pr_save_energ...
