– German Village Achieves Energy Independence … And Then Some (BioCycle, August 2011, Vol. 52, No. 8, p. 37):

Wildpoldsried produces 321 percent more energy than it needs and is generating $5.7 million in annual revenue — a remarkable accomplishment for a modest farming community that has been able to invest in new municipal infrastructure without going into debt.

IN 1997, when the newly elected Mayor and Village Council of Wildpoldsried, Germany took their posts, everyone agreed that its goals should be to build new industry, keep initiatives local, bring in new revenues and create no debt. Those goals included construction of a new sports hall, theater stage, pub, and retirement house. Without going into debt, the mayor and council assumed it would take several decades to achieve. But clever thinking, a national policy that “paid back” on investments in renewable energy and a community-supported vision of environmental and economic stewardship, have led to fulfilling those goals in significantly less time. This article tells the story of Wildpoldsried, a small agricultural village in the state of Bavaria, which serves as a model of how to achieve community sustainability in the 21st century — and remain debt-free.

In May 2011, 14 years later, Mayor Arno Zengerle announced at a town hall meeting that it’s “half time” of his third term. He walked the community through a massive list of accomplishments that include nine new community buildings (including the school, gym and community hall) complete with solar panels, four biogas digesters with a fifth in construction, seven windmills with two more on the way, 190 private households equipped with solar, a district heating network with 42 connections, three small hydro power plants, ecological flood control and a natural wastewater system. Wildpoldsried (pop. <2,600) now produces 321 percent more energy than it needs and is generating 4.0 million Euro (US $5.7 million) in annual revenue. This is a remarkable accomplishment for a modest farming community that turned a village with no industry into an industry of renewable energy with the help of local entrepreneurs and pioneers. Small businesses have sprung up to sell and install technologies and provide services to the renewable energy installations — from solar panels to district heating to the anaerobic digesters and energy efficiency retrofits.
