I ts Time to Get Real About Climate Protection 23 Since 1997 Colorado has installed nearly $4 billion worth of wind turbines and solar panels. These investments in a clean energy economy are a tremendous accomplishment. But you will know we are serious about tackling climate change when we begin focusing on reducing METHANE emissions, not just on carbon dioxide. Randy Udall
