Experience energy

Köln International School of Design, Mar.2012

Using energy is essential in modern life, but it is somehow difficult to understand. For example, can we imagine the amount of energy represented by our monthly electricity bill? Since energy is invisible, there is always a gap between reality and our understanding. I converted the energy consumption of an electric bulb into weight, in order to understand the difference between a conventional bulb and a new energy-saving one (above). The conventional bulb form was cast in solder-led, and the energy saving lamp was cast in plaster. The difference in energy consumption (60W / 11W) was converted into weight difference (1270g / 205g).
If you put these bulbs at 10 m hight, the potential energies are almost as equvalent as the 1 second energy consume of original bulbs.
