Malmö, a Swedish city with about 342,457 (2012) inhabitants, has the goal to be run by 100 % RE by 2030 and the city aims to be climate neutral by 2020. In 2014, the city produced 30% of its energy needs from RE, mainly from wind, waste incineration, water hydro and industrial leftover heat.
In 2009, the city of Malmö launched the ‘Environmental Program’, a city-wide project, in order to reach the goal of operating on 100% RE, improve the sustainability of the city and the quality of life of its citizens. Furthermore a variety of environmental goals have been set, e.g. the reduction of the energy consumption by at least 20% by 2020 and by a further 20% by 2030, and the reduction of GHG emissions by at least 40%. Moreover the rail traffic, other electrically driven public transport and the network of cycle lanes should be improved and extended.
The Program engages city officials and citizens in a dialogue and gives them the opportunity to participate in the implementation phase. It has benefited from committed local politicians, private investment in RE, strong co-operation with regional stakeholders and knowledge of the locally available RE sources.
The City runs all municipal buildings on 100% RE and has already been reducing greenhouse gas emissions with a focus on energy efficiency, reducing energy use, and investing in renewable energy. Over the past 20 years, the city’s disused brown fields and industrial spaces have been re-developed and revitalised with energy efficient buildings and attractive public spaces. The Western Harbour (Västra Hamnen) with housing estates operates already on 100% locally produced RE. The houses are powered by a 2 MWh wind turbine that provides 99 % of their electricity and 8 kWh of solar PV. Western Harbor also has an innovative district heating and cooling system. In the summer, cold water from the previous winter, which is being stored 90 meters underground in aquifers, is pumped up by wind-powered electricity and run through a heat pump for district cooling. Once the water is heated it is pumped back down into the aquifers where it is stored for heating buildings in the winter. Furthermore, Malmö is home to Sweden’s largest solar energy plant, the. Sege Park’s 1250 m² photovoltaic panels.
