Given the recent glut of renewable energy announcements, it's a welcome perspective to temper optimism with a dose of reality.
During an interview at the recent Clean Energy Ministerial (CEM7) conference in San Francisco, Michael Brune, executive director of the Sierra Club, spoke of his optimism about the transition to a renewable energy future, the enormity of the work that is still necessary and the role of the activist community to accelerate this effort.
“It does feel like we’ve turned a corner, but we’ve still got a long way to go," said Brune.
