Colorado has become a national leader in renewable energy production, thanks in part to former Gov. Ritter's leadership through his New Energy Economy effort. We have tremendous solar, wind, geothermal and agricultural (for biofuels) resources, and we can harvest a significant amount of clean energy if we can make the proper investments in infrastructure. We also have institutions such as those on the Colorado Renewable Energy Collaboratory team of CU-Boulder, CSU, Colorado School of Mines and NREL that are performing cutting-edge renewable energy research. Clean energy is certainly an environmental issue, but it's also a major part of our economy, partially because successful renewable energy businesses generate jobs and revenue from selling the fuels or electricity.
