"Yesterday when I went to Gänsemarkt in Hamburg, Germany, I was staggered to see an igloo which was built from 322 fridges. It is titled “Wastefulness is the biggest source of Energy”. You can see it until 9th of November. The iglu is an art project by Berlin-based artist Ralf Schmerberg and is supported by an energy provider. On the inside there is some funny art with many old blinking electronical devices arranged in a very colorful setting. At the outside they had a huge electricity meter which showed how much energy would be consumed by all those very old fridges. It said that with a more efficient use of energy, Germany could save around 40%. All in all I found that a very unique way to raise one’s voice against the waste of energy."
