Just a taste of the latest milestones: In Norway, more than half of all new car sales are electric or hybrid models, just as entire fleets of ferries that run on batteries are being produced. Last year, Denmark set the world record for a wind-powered economy, generating 43% of electricity from wind power. The Swedes and Finns are paving the way in producing biogas from waste and vegetation and turning it into fuel for heating and automobile engines. Iceland and Norway already run on renewable energy, so abundant are their geothermal and hydro resources, respectively.
Copenhagen, Denmark's capital, is one of Europe's smartest cities, or low-carbon sustainable cities; two-thirds of its residents cycle to work, while only 9% drive cars. There are 233 miles of bike path, and the city is continuing to expand the routes and bridges for cyclists. In few other big cities is the downtown air so clean, which lands Copenhagen among the world's most livable cities year in, year out.
