Towards a sustainable energy future: realities and opportunities.

My purpose in this paper is threefold. First, I would like to examine why the world needs us to produce more energy. Second, I will look at the range of energy sources available for a sustainable future. A number of myths have grown up around the various energy sources and their relative contribution to addressing the global energy challenge: I will seek to dispel some of those. Third, I want to highlight what I see as an urgent need: for more informed decision making and more action in this complex area.
