Randy Udall is a leading activist in promoting energy sustainability and the former director of the Community Office for Resource Efficiency (CORE), a nonprofit organization that promotes renewable energy, energy efficiency, and green building in western Colorado and beyond. CORE's partnerships with individuals, governments, and utilities led to Colorado's first solar energy incentive program, the world's first renewable energy mitigation program, the world's stiffest carbon tax, and some of the most progressive green power purchasing programs in the country. Recently, he served on Colorado Governor Bill Ritter's climate action panel. He is also a co-founder of the Association for the Study of Peak Oil-USA, and he speaks widely on why "energy is an IQ test Americans tend to fail."
