OSEA has been led and managed by Kristopher Stevens since May 2008 with Deborah Doncaster, Paul Gipe and Gwen Glover having served before him.

OSEA has been at the vanguard of sector transformation through various policy papers which have helped inform the creation of key policies, regulations and programs such as the Renewable Standard Offer Program (RESOP) and the Green Energy and Economy Act.

OSEA has hosted and co-hosted five successful international exhibitions and conferences to advance the sustainable energy sector with new insights, information and business opportunities.

Previous conferences had been held in Beijing, Berlin, Buenos Aires, Melbourne, and New Delhi.

The OSEA community - staff, interns, volunteers, members, friends and supporters - are actionists (as opposed to activists) looking for (and working on) solutions.

They work pro-actively to build bridges between stakeholders and seek ways to improve Ontario's energy system collaboratively recognizing that community, industry and government should all play a role in shaping Ontario’s energy future.
