Boulder is the first city in the United States which imposes an additional tax on residents who use electricity made from coal. About a third of the total waste steam here is recycled.

 

The city has one of the largest solar hydronic systems in the country and it is ringed by 43,000 acres of protected open space, which is nearly three times the landmass of Manhattan. Boulder is also laced with greenways and designated bike lanes.

 

In Boulder you can get anywhere on bike, almost as fast as a car can. As well as in this beautiful city, the community program gives bikes to homeless people in exchange for work and there’re a bounty of new routes and trails in recent years.

 

The Boulder Creek Path is the main artery of Boulder bikeland. But Boulder is not for everybody. Some people hate the place. The town is rigorously conformist in its alternative way- if you wear river sandals and sport rucksack.

 

All the restaurants there use organic ingredients that are free of synthetic chemicals and pesticides.
