OSEA is a respected advocate, facilitator and business catalyst bringing the public, commercial and community sustainable energy sector and their supporters together to address emerging trends and the development of healthy, prosperous and ecologically sustainable communities across Ontario.

OSEA’s vision is of a prosperous Ontario with a thriving sustainable energy sector, good jobs, resilient communities and healthy environments powered, heated, cooled and moved by portfolios of sustainable energy.

OSEA’s mission is to advance the association’s vision by raising public awareness, advising decision makers and establishing forums for new market opportunities and collaboration. 

What is Sustainable Energy?

Sustainable energy involves the effective and efficient production and use of energy from various distributed sources matched in scale and quality to the end use.  Proponents of sustainable energy recognize that energy is a means to an end, not the end itself.  Sustainable energy is about producing and using energy in a way that meets our needs and improves the quality of our lives while also ensuring that the ecological system that sustains us, our economy and society is healthy and capable of supporting future generations at a similar level long into the future.

Membership is open to all individuals and organizations that support OSEA’s values, vision, and mission upon approval by the membership committee.
