Except you haven't because electricity is charged in kW/h, not based on current drawn by individual devices. A 100W lightbulb consumes a similar amount of power to a 100W TEC and thus costs a similar amount to run (probably cheaper to run the bulb because you don't lose power transforming the voltage to 12VDC first).
