European cooperation in Alheim and Dunleer: energy efficiency and renewables in building refurbishments
Alheim has long been part of the local energy transition. In 2012, the town in Hessen in central Germany won the Renewable Energy Agency’s Energy Municipality of the Month award. Since then Alheim is still strongly involved in the Energiewende – in 2016 it has been voted for the most sustainable municipality in Germany. Alheim advanced many projects in its electricity and heating sectors through renewable decentralized power plants.
Now, it is going one step further to share its experience with other energy system transformation actors. In 2019, it therefore joined Energiewende Twinning Towns. In this project, Alheim’s twin in Ireland is Dunleer, a town 60 km north of Dublin. The two municipalities have found common ground in their initiatives for participation and educational work in the energy system transformation. While Dunleer is a pioneer in the field of building renovation for private individuals, Alheim has mainly renovated and modernised numerous municipal properties.
“By explaining the advantages of energy efficiency and renewables, we have succeeded in getting the citizens of Dunleer to turn their attention to the topic of building renovation and modernisation.” – Eugene Conlon, Energy Team Dunleer
In founding the Dunleer Sustainable Energy Community, citizens, scientists, politicians and businesspeople joined forces to enable energy system transformation. The main vision is to meet the European climate protection targets by 2030. In the last four years, they have already achieved a great deal: Educated 500 people from across Ireland on steps they can take in their homes to reduce energy and use more renewable energy solutions. This education programme is called the Energy Ambassador project with participatory information events where the audience is inspired, educated and supported in taking steps for greater energy efficiency in their homes and places of work. Dunleer sees education, acceptance and participation around energy efficiency and renewable technology as an important building block for the future of the energy transition. Another action by the group has been the retrofitting of 200 buildings with measures of insulation, temperature controls and new renewable heating solutions such as air source heat pump, biomass boilers or solar panels. The energy efficiency of the buildings has improved, people are more comfortable in their homes and also this has resulted in considerable cost savings. The modernisation project is financially supported by the Sustainable Energy Authority of Ireland Energy suppliers and homeowners. Generation is a key part of the objectives of the Dunleer community and understanding how Alheim has achieved its generation will be a key learning Dunleer will achieve from this twinning.
Alheim had already renovated and modernised municipal buildings as part of intermunicipal cooperation between the three German municipalities of Bebra, Rotenburg and Alheim. That project focuses on intermunicipal cooperation for urban development without growth and promotes building refurbishment. Similar to the Energy Ambassadors in Dunleer, climate protection education in Alheim was considered right from the start. At the environmental education centre in Licherode, citizens are trained to pass on their knowledge about the energy transition to others. In addition, climate protection and renewables are anchored in school curricula and even in kindergartens.
"The renovation of municipal buildings was just the beginning in Alheim – now it's all about private households and increased energy efficiency for citizens.” - Petra Herzig, municipality of Alheim
Renewables have also been integrated in the community’s landscape for a long time because Alheim invested in solar power plants at an early stage. Three solar parks within the municipality ensure that Alheim can cover almost 100 percent net of its electricity consumption with renewable energy. At the same time, regional added value has grown because local solar power companies have created jobs and investments were made in renewables. 58 million Euro have been invested with a local value added in earnings of 6 percent. Alheim managed to allow citizens to participate in the growth of renewables, including the local heating network, which is to be fed by solar thermal and bioenergy. The participation of citizens is achieved by listening, informing and by giving the opportunity to get involved and create the projects together. There will be information events and close cooperation with other municipalities that have already successfully implemented citizen participation in local heating networks.
In the Energiewende Twinning Towns project, Dunleer and Alheim see this as an opportunity to share their experience in building refurbishment, generation, discuss climate protection, education concepts, and advance the energy transition. The first joint workshop will take place as part of the Alheim Climate Protection Week in October 2019.
