A look of concern grew across Gretchen Bunn's face as she thought about what might happen Monday when Democrats come to town for the second time in a century.
Will there be traffic jams, protesters, even riots, worried the saleswoman at Rockmount Ranch Wear, standing amid floral western shirts and cowboy boots.
It's anyone's guess what the four-day Democratic National Convention will mean for the city with 50,000-plus attendees and the glare of national and international media. But it's clear what city boosters want to project. Just as they landed their first Democratic convention in 1908 to prove that Denver had morphed from cow town to cosmopolitan city, they are eager to show off a city transformed once again.
This time, they are selling a "new West" city that has emerged from the boom-and-bust petroleum era into a center of environmentalism, embracing renewable energy with the same gusto as it once welcomed oil speculators.
"Denver has grown up," says John Hickenlooper, the city's mayor. "Back in the late 1970s and early 1980s, energy was really the only game in town."
Denver's new green sensibilities will be felt -- whether they like it or not -- by conventioneers. Mayor Hickenlooper has challenged organizers to make the Democratic National Convention (DNC) the "greenest convention in the history of the planet." That means a lot of organic foods, as many as 900 volunteers dedicated to making sure everyone recycles, 1,000 bicycles available to the delegates, and a push to offset the convention's carbon emissions with investments in alternative-energy and other green ventures.
"We are doing as much or more than other cities" for the environment, says Michele Weingarden, director of Greenprint Denver, the mayor's initiative to make the city a beacon of environmentalism. "This is a chance to show that we are a green convention town."
In the suburban town of Golden, Colo., east of the foothills of the Rocky Mountain's Front Range, lies a compound of low-slung buildings that make up the US Department of Energy's National Renewable Energy Laboratory. It's proved to be a major magnet for private alternative-energy ventures eager to take advantage of its expertise.
The wind turbine builder, Vestas Wind System, that opened in March has already announced plans to expand, and Houston-based ConocoPhillips said earlier this year that it would build an alternative-energy research lab in Louisville, outside Denver.
But fossil fuels remain a major player here today and the natural-gas industry is booming across Colorado. In the metro region alone, traditional energy companies employ 14,560 people, making fossil fuels the second-largest industry in the area, according to the Metro Denver Economic Development Corporation. The government is the region's largest employer.
But renewables are catching up and now employ 13,941 people in the nine counties that make up the Denver region. The renewable-energy lab's funding rises and falls with the economy and price of oil, says lab spokesman George Douglas. These days have been good for renewable research.
