How much energy is needed to toast a slice of bread? - Making energy usage transparent


Each year we receive a bill form our energy provider telling us, that we have consumed a certain amount of energy. Most of us tend to forget that number immediately. Domestic energy usage is intransparent to the user, because there is basically no feedback or usable information of energy usage at all.
This talk looks at the advantages, disadvantages and problems of transparent, tangible and open energy usage. Private homes will be considered in the first place, but also buildings, communities and cities are considered. Therefore, different projects, concepts and studies will be presented.
