The Energy Efficiency Office provides technical, policy and administrative expertise towards the City's goals of using a 25% green energy supply. The EEO participates in a series of partnerships with the goal of establishing a sustainable energy infrastructure with this specific green power component. Some project examples include a solar residential domestic hot water, biogas green energy recovery with the City of Toronto at landfill sites and treatment plants and the Fuel Cell Demonstration Project at Exhibition Place.

Fuel Cell Demonstration Project at Exhibition Place
The Fuel Cell Demonstration Project was an awareness program held over three summers at Exhibition Place (2003-2005). The event was a partnership with several producers of fuel cell technology and equipment, to demonstrate the potential reductions in emissions by the City.

Green Energy Procurement
The EEO provides project reviews and assessments of green energy and electricity projects. Proposals under consideration are vetted against technological and financial feasibility. This is in support of a green energy procurement policy, which the office is helping develop with several divisions.
