It is the first prison of its kind; it’s ecological. This prison is situated in Norway. Ecological has nothing to do with the type of criminals in this place, it is still home to notorious criminals. The prison uses solar panels in order to produce energy and most of the food supplies are produced in the prison (or around it) as well. The solar panels cut the third-party electricity needs by 70% which I think is pretty good. The food is also good quality and the leftover food is sold to other prisons. So they are making quite a good amount of money and saving up too.
