Most people in the cleantech community recognize that Santa Clara Valley is a unique and beautiful place with world-class universities, piles of venture capital and an entrepreneurial history second to none, but recent trends indicate that cleantech companies are beginning to consider a new home base on Colorado’s Front Range. According to the Milken Institute’s “Best Performing Cities 2013”, four of the top 25 large cities in the U.S., were from Colorado’s Front Range (Boulder, Denver, Fort Collins and Greeley). The Institute cited “[t]echnology and energy were the forces powering this year’s top performers, even more than in 2012,” and the report noted that Denver, for instance, had a very strong business climate, skilled work force and strong international links. These assets have led to Denver’s high-tech gross domestic product concentration exceeding the national average by 60 percent.
