1 Costs are based on average PSE residential rates for electric service ($.088594 per kWh [first 600 kWh] and $0.107172 [remaining kWh]) and natural gas service ($.97449 per therm) as of February 2013. Rates are based on usage of 1,000 kWh per month and 68 therms per month. These rates do not include the basic monthly charge.

2 Electronics like TVs, DVD players and game consoles can consume power even when not in use. Plug these items into a power strip that you can switch off when not in use to prevent standby energy use.
