A device and a method of metering and displaying immediate and/or accumulated energy consumption at a place of consumption, such as electricity, water or heating consumption in a household, said device comprising a recording unit which records and sums an immediate energy consumption on the basis of regular measurements and stores there measurements for the calculation of an average consumption, a display comprising at least one display unit capable of displaying the relationship between an accumulated energy consumption and the calculated average consumption for a selected period of time on a percentage scale. The display preferably exhibits a first display unit which displays the accumulated energy consumption on an energy scale preferable from 0-200%, where 100% corresponds to the calculated average consumption, and a second display unit which may show the immediate power consumption relative to a selected reference consumption, preferably on a percentage power scale of 0-100%, where the selected reference consumption, which corresponds to 80% on the power scale. A consumption meter according to the invention hereby ensures that the user is more easily motivated to cut down on the energy consumption because of e.g. an energy saving measure, such as the use of low-energy bulbs in one or more lamps or the like.
