This entry is the first of a series of posts written by members of the World Bank's Development Research group's Environment and Energy team on economic and policy issues involving energy and climate change mitigation.
Issues relating to energy are among the most important and difficult challenges confronting the world today. Providing sufficient energy to meet the requirements of a growing world population with rising living standards will require major advances in energy supply and efficiency. Doing this while mitigating the risks of climate disruption will be an even more challenging undertaking. It will require a significant shift in the historic pattern of fossil-fuel use and a major transformation of the global energy system. Especially in the developing countries, the choice of technology, policy, and economic levers that will be used to transform and expand their energy systems will have profound implications for their growth, international competitiveness, and economic security and prosperity. This overview focuses on the challenges related to electricity supply; subsequent blogs will address other parts of the energy system.
