Currently the community is served by two energy suppliers of electricity and gas, but local politics consider taking the energy grid under their own care.For many years the local authorities have provided sponsorship for the population within water-conserving policy (since 1996) or for the purpose of using solar energy (photovoltaic and solar thermal systems since 2000). Since February 2012 there has been a new support programme for the residents. The programme promotes energy efficiency of newly constructed and old existing buildings as well as solar energy used for water or space heating. For the years 2012 to 2014 575 000 EUR is provided. On the 28th of March 2012 a kick-off event took place for the citizens to implement a climate change concept. It was attended by about 80 people.
