Energy is at the core of the way Canadians live. Yet recent research indicates that North America's supply of oil - our most consumed source of primary energy - may only last until 2025. So what happens when this valuable resource runs dry? In this highly readable introduction, Peter Sinclair examines the history of energy production and consumption leading to the impending energy "crisis." What policy decisions have been made along the way and in whose interest? From the Alberta oil sands to offshore drilling in Newfoundland and Labrador, Sinclair delves into the hot button issues that affect Canadians today. Looking ahead, he points to which alternative and renewable energies we may rely on and the environmental, social, and political pressures that are increasingly pushing Canadians toward a critical change.
