As the second largest energy consuming sector in Ontario, representing an expenditure of over $680 million in electricity and $275 million in natural gas annually, municipal governments do not need to look beyond the decision-making realm of council chambers to make a difference. Municipal governments are leading the way in energy conservation and greenhouse gas reduction. The Audit++ Program is a compilation of 42 municipal case studies and lessons learned. Each case study highlights operational and technological improvements that can be made to improve energy efficiency of similar facilities across Ontario’s municipalities. An index and link to the case studies follows below.
