National Clean Energy Week was conceived in June by the Coalition of Responsible Energy Solutions. During July and August the organizers attracted partners, sponsors and speakers. They developed a week-long agenda and located venues for the expo, symposium and panels. Festivities began with a welcome reception for invited guests at Google’s Washington, D.C. office on Sept. 25. Tuesday’s NCEW symposium included talks by Energy Secretary Rick Perry and Interior Secretary Ryan Zinke; briefs from four members of Congress, including Sen. Lindsey Graham (R-S.C.); roundtable discussions and talks by clean energy technology leaders.
