|Heliotrope - Plus Energy|
This idea was adopted on a community scale in Bavaria, where the 2600 residents of Wildpoldsried got together in 1997 to establish goals to become a net energy exporter. Richard Defendorf has posted an excellent review of the project guidelines, the actions and the results – an annual power surplus of 321%. Ah – and therein lies the rub. What does one do with extra power? Wildpoldsried proposes to convert the PV generated power into methane, which can be stored for future use. This raises questions of power lost in this multi-step process, the economic feasibility of this, were it not for substantial government subsidies of the PV panels, and alternatives both to generation and storage.

Positive energy is the first step. And then we take lessons from the automotive industry, and add air cleansing filters, wetlands water purification, wildlife support, and above all – renewed community. For the main lesson learned from Wildpoldsried is that it does indeed take a village to tackle global issues.
