In the 2004 November election, Colorado voters, by a solid margin, approved Amendment 37, which requires Colorado's largest utilities to use wind, solar, biomass or small hydropower to obtain 3 percent of their electricity by 2007 and 10 percent by 2015.
This was in spite of a well-funded campaign by the utilities to defeat it.
