Here's a breakdown of the biomass quantities necessary to heat Juhnde and supply it with energy year-round:

* 9,000 cubic meters of manure from pigs and cattle;

* around 300 hectares of energy crops, which make up 25 percent of the village's total crop yield; and

* 300 tons of wood chips per year, the equivalent of 10 percent of the surrounding forest's annual growth.

In this image, a local farmer drives harvested energy crops to the bioenergy plant, where they will be stored under large tarps until ready for processing.
