The key role of energy in global problems is clear. Some two-thirds of the greenhouse-gas emissions that are causing climate change trace back to fossil fuel use. A renewed scramble for oil is raising fears of a new generation of geopolitical conflicts. Global economic instability correlates strongly with energy-price volatility. Economic development is in significant part defined by the process of overcoming energy poverty, yet 1.6 billion people still lack access to even the most basic energy services.
Only recently has it become clear that these seemingly disparate issues are a collective manifestation of a dysfunctional energy system. Globally and at the national level, energy is still conceptualised and managed in terms of energy sources, not in terms of the energy services those sources provide. Yet consumers of energy services have no particular interest in what sources of energy fuel their production, transportation, lighting, heating, air conditioning, or appliances. The existing paradigm serves to rigidify decision-making at a time when extraordinary flexibility and rapid change are essential.
