Net Energy Positive Passive House

The Passive House in the Woods in Hudson Wisconsin officially clocked a net-energy positive meter reading in 2011.

What does that mean?

In short, it made more energy than it consumed. While we predicted this with our energy models, we found and learned through monitoring that some equipment and appliances use more energy than assumed. On the flip side, user behavior plays a major role as well and can effectively lower energy consumption over the predicted model. (Source)

Ghost Town Ecoaldeas

It’s a utopian fantasy- discover a ghost town and rebuild it in line with your ideals-, but in Spain where there are nearly 3000 abandoned villages (most dating back to the Middle Ages), some big dreamers have spent the past 3 decades doing just that.

There are now a few dozen “ecoaldeas” – ecovillages – in Spain, most build from the ashes of former Medieval towns. One of the first towns to be rediscovered was a tiny hamlet in the mountains of northern Navarra.

It was rediscovered in 1980 by a group of people living nearby who had lost their goats and “when they found their goats, they found Lakabe”, explains Mauge Cañada, one of the early pioneers in the repopulation of the town.

The new inhabitants were all urbanites with no knowledge of country life so no one expected them to stay long. At first, the homes weren’t habitable so they lived 14 in a large room. Slowly they began to rebuild the homes and the gardens.

When they first began to rebuild, there was no road up to the town so horses were used to carry construction materials up the mountain. There was no electricity either so they lived with candles and oil lamps.

After a few years, they erected a windmill by hand, carrying the iron structure up the hill themselves. “Even though it seems tough and in some ways it was, but you realize you’re not as limited as you think,” says Mauge. “There are a lot of things people think they can’t do without a lot of money and there’s never been money here.”

In the early years, they generated income by selling some of their harvest and working odd jobs like using their newfound construction experience to rebuild roofs outside town. Later they rebuilt the village bakery and sold bread to the outside world.

Their organic sourdough breads now sell so well that today they can get by without looking for work outside town, but it helps that they keep their costs at a minimum as a way of life. “There’s an austerity that’s part of the desire of people who come here,” explains Mauge. “There’s not a desire for consumption to consume. We try to live with what there is.”

Today, the town generates all its own energy with the windmill, solar panels and a water turbine. It also has a wait list of people who’d like to move in, but Mauge says the answer is not for people to join what they have created, but to try to emulate them somewhere else.

“If you set your mind to it and there’s a group of people who want to do it, physically they can do it, economically they can do it. What right now is more difficult is being willing to suffer hardship or difficulties or… these days people have a lot of trouble living in situations of shortage or what is seen as shortage but it isn’t.” (Source)
