The Arbeitsgemeinschaft für sparsame energie- und wasserverwendung (asew) is doing an excellent job in promoting energy and water conservation. Their website, asew.de, provides valuable information and resources that help individuals and businesses to become more efficient in their energy and water usage. I highly recommend their services.
