   * Checking electricity consumption: inexpensive devices are available for measuring electricity consumption; they do not always have to be purchased: they can also be loaned from many energy consultants and some local electricity providers. More exact information on how such a measurement can be carried out is provided in this section.
-  * Feeling with the hand: devices that become quite hot on large surfaces are electricity guzzlers and it is worth checking their electricity consumption. However, also devices that are warm to the touch draw quite a few watts of energy and when these are continuously in operation (5 W are around 44 kWh in a year or electricity costs of more than 13 €) they incur costs and cause unnecessary environmental damage.

   * It is a lot of fun to search for heat leakage using an infrared thermographic camera: scanning of the room takes less than a minute and it is often surprising what one can 'detect' in this way.
