The Bullitt Foundation is nearing the end of grant-giving that has infused the Northwest environmental movement with more than $200 million. The relatively small foundation has had an outsized impact as it pushed the region toward a greener future. Much of that is due to President and CEO Denis Hayes, left, known for organizing the first Earth Day. He walks with Deborah Sigler, who leads tours of the Bullitt Center in Seattle, aka the “Taj Mahal of energy efficiency.”  (Photo: Ellen M. Banner / The Seattle Times)
