Similar situation here, but in Finland. I use 14 MWh of /electricity/ each year (medium-sized house, three-person household). That excludes the firewood that we use for heating the sauna, and to keep the house warm during winter, when the cold is too much for the heat pumps to manage. Oh, and travel.

In order to reach the goal in the article, a three-person household would need to restrict energy use to 52560 KWh/year, /including/ all those things AND the production of everything that household consumes.

I can't see how it's even remotely possible with today's technology and societal climate. That being said, there's no harm in researching and developing more efficient technologies. I don't even want to think about how bad the energy crisis would be if we were all still using 60w/40w lightbulbs.
