<p>PROBLEM TO BE SOLVED: To provide household energy saving supporting method and device which help to reduce energy consumptions as a whole by setting target values of a plurality of energy consumptions such as power and gas used in each household as accurate as possible. SOLUTION: This device converts the consumption target value of each energy into light and fuel costs being a common unit, calculates target light and fuel costs corresponding to the total amount of a plurality of energy consumption target values, similarly converts the consumption actual result value of each energy into light and fuel costs to calculate actual result light and fuel costs corresponding to the total amount of a plurality of energy consumption actual result values and comparatively evaluates the target light and fuel costs and the actual result light and fuel costs.</p> |
