Green Cities

What makes a city green? It’s a huge challenge for cities to be earth-friendly. Not only do they have lots of people, buildings, traffic, trash, and air pollution, but they also consume more than half of the world’s energy.Many cities in the world have taken up the challenge to be earth-friendly. Look at what some of these cities have done:

Reykjavik, Iceland, is run entirely on green energy. Its transit system uses hydrogen buses and most of its buildings use non-polluting energy sources like geothermal and hydroelectricity.
Malmo and Stockholm in Sweden are noted for their green spaces and parks and for successfully cleaning up their water and air.
Portland, Oregon, was one of the first American cities to focus on earth-friendly transit with light-rail and bike paths to encourage people to leave their cars at home.
Curitiba, Brazil, uses unique green methods for maintenance. Their grass parks are trimmed by sheep!
Vancouver, British Columbia, uses wind, solar, and water energy to generate power. Nearly all of the city is powered by clean hydroelectricity.
