Ontario's energy supply mix is evolving.

Fostering a culture of conservation and developing renewable sources of energy are cornerstones of the provincial government's vision for Ontario's electricity future. This can be seen in the diversity and growing availability of alternate power sources coming online in Ontario's power grid. However, to meet the increasing demand for power in the future, it remains important to reduce our consumption now. Please do your part in promoting the adoption of clean energy sources.
