Assessments
Simpson publicly supported increasing U.S. energy efficiency and the congressional record shows he worked on amendments tied to energy-efficiency funding. That is real legislative effort, but the evidence does not show that a national increase in energy efficiency was actually enacted or completed, so this is credit for advancement rather than full delivery.
The evidence shows Simpson publicly supported increasing U.S. energy efficiency and took concrete legislative action related to energy efficiency and renewable energy funding. However, it does not establish that the promised outcome, an actual increase in U.S. energy efficiency attributable to his actions, was delivered. Because there was a serious legislative effort but no demonstrated fulfilled outcome, this is best classified as not delivered with an effort badge.
