  Basel is at the forefront of a national vision to more than halve energy use in Switzerland by 2050. To research, develop and commercialise the technologies and techniques required for the country to become a 2000 Watt society, a number of projects have been set up since 2001 in the Basel metropolitan area. These include demonstration buildings constructed to Minergie or Passivhaus standards, electricity generation from renewable energy sources, and vehicles using natural gas, hydrogen and biogas. A building construction law was passed in 2002 also which stated that all new flat roofs must be greened leading to Basel becoming the world's leading green roof city. This was driven by an energy saving programme.
  
  A hot dry rock geothermal energy project was cancelled in 2009 since it caused induced seismicity in Basel.
