Many cities around the world are developing new methods to become more energy-efficient and create eco-friendly infrastructure.
The city of Malmö, in Sweden, used to be a polluted industrial center, home to nuclear power plants. Nevertheless, since 2000, city officials have closed the plants and are committed to make Malmö, carbon-neutral by 2020 and able to run on entirely renewable energy by 2030. It is expected that by the end of this year, Malmö’s fleet of municipal vehicles will run on hydrogen, electricity or biogas created from collected food waste.
In Malmö, the Western Harbour district has become a pioneer for sustainable building. At the harbor a wind turbine that used to be part of an abandoned shipyard, today provides electricity for parts of the city.
The district also uses an aquifer storage system to collect rainwater that is pumped using energy from the turbine to eventually heat homes in the winter and cool homes during the summer. Another development, in Flagghusen district, has made vegetated roofs and walls a mandatory building code.
Malmö authorities hope that the Western Harbour will continue to be a green population center. The area can house 10,000 people and expects an additional 20,000 to work or study there.
