At Samsø Energy Academy we have a jar filled with black marbles.
In the movie “Black Marbles” by Anders Matthesen, white and black marbles are awarded to the realtor Alex Klien, who has been in a car accident. Suddenly, he finds himself in the middle of a quiz show about his personality and personal traits. The number of good, white marbles or bad, black marbles determine wether or not he will survive.Fortunately, it is not as dramatic when it comes to the Energy Academy’s jar of marbles!
On Samsø, we use the jar of black marbles to monitor how many oil-fired boilers have been replaced with renewable energy sources such as heat pumps or district heating. In 2009 when we started putting marbles in the jar, around 1/3 of the houses on Samsø were heated by oil-fired boilers, equalling 750 households. In 2011 we passed 100 replaced oil-fire boilers. So far, we have put 250 black marbles in the jar and of course, we hope some people have replaced their boilers without asking us for help.
