The response from EPA's Alex Baker, which was not available when this article was first published, has been added.

Aspen, Colorado, already has a strong residential program for promoting energy conservation and renewable energy. The Renewable Energy Mitigation Program, or REMP, requires builders of large homes (those over 5,000 ft2, or 500 m2) or those with snowmelt systems, spas, or heated pools, to install renewable energy systems or pay a mitigation fee...
