A green energy revolution is underway in Canada and renewable technologies have been pushed to the forefront of the energy policy discussion. With the 2009 passage of Ontario's Green Energy and Green Economy Act, the province seeks to become the leading North American carbon-free jurisdiction. But can the province's manufacturing capability and immense human capital be mobilized to achieve this goal? Is it realistic for Ontario to go green while at the same time providing a steady energy supply to consumers and industry at affordable prices? And, perhaps most important of all, can we afford the green transformation? With the green energy issue posed to be a central issue in the next election, Green Ontario provides a hard-nosed assessment of what it will take to make the transition to a deliberate portfolio of renewable energy technologies a reality. Green Ontario will be compulsory reading for policy-makers, environmentalists and everyone concerned about the future of our planet and what it will take, both politically and financially, to secure a sustainable future.
