I used to work at the Bonneville Power Administration when op-ed writer Angus Duncan was at the Northwest Conservation and Power Planning Council. (“Opinion: A future of reliable, clean energy depends on building out Oregon’s power grid,” June 23). His article stresses wind and solar development and new transmission lines as the methods that can meet load demand and minimize carbon dioxide emissions. He’s wrong not to add that nuclear resources will be desperately needed in that mix – resources like small modular reactors – if we are to have any hope of going green.
