Environmental advocates from the Western states met in Denver to explore the implications of the U.S. Environmental Protection Agency’s Clean Power Plan. David Farnsworth highlighted the role of renewable energy sources as a significant compliance option, and encouraged the advocates to nurture the dialogue with state regulators, consumer advocates, and other states. By recognizing the decision-makers’ goals and constraints, advocates can help states meet compliance goals, while finding low-cost solutions that serve the interests of all stakeholders.
