This week’s Energy Rant is courtesy of guest writer, Brian Uchtmann, Evaluation Engineer at Michaels Energy. Energy efficiency programs remind me of a joke about economists; here is my version for evaluators. Feel free to use this joke at your next party. Two energy efficiency program implementers and an evaluator go on a deer hunt. In the distance, they see a magnificent buck. The first implementer aims and fires. The evaluator yells “Missed, way too high!” and jots down a few notes. The second implementer lines up and shoots. The evaluator yells “Missed, way too low!” and adds an entry…
