Sweden: One Tonne Life. The project begins. The family arrives in the house

In TreeHugger: This week in the suburbs of Stockholm, an unprecedented low carbon lifestyle experiment has begun. 
The Lindell family have moved into a solar powered prefab house that is specially designed to minimise energy consumption. The family's aim is to see if they can radically reduce their average carbon footprint of 7 tonnes per year, down to 1 tonne. (Image courtesy one Tonne Life)
