Aspen, Colo. (AP) - Aspen is looking into whether geothermal energy could heat and cool buildings and keep sidewalks free of snow.
The city has applied for water rights under the new Colorado Geothermal Act and is seeking a federal grant to pay for the project, estimated to cost $3.5 million.
The City Council last week commissioned a $33,000 report for state water court to determine the effects of the project on the Roaring Fork River.
A reconnaissance study last year found that warm water beneath Aspen may be sufficient to operate a geothermal system.
The city's goal is to find enough geothermal energy to heat 1 million square feet, the equivalent of 10 large hotels.
