The Conservation Fund supports innovative conservation technologies, practices, research and programs that have the potential to deliver significant energy savings. Since 2005, the Conservation Fund has provided financial support for more than 200 innovative energy projects across Ontario.

The Fund seeks projects that will lead to large-scale transformation in the marketplace or a change in consumer behaviour; projects that demonstrate the energy saving potential of emerging technologies and investigate novel conservation concepts.
