Energy

Energy presents one of the world's most complex and persistent challenges. Energy access and use is a necessary and powerful driver of socioeconomic development; on the other hand, the burning of fossil fuels for energy is altering the Earth's climate. Transitioning to a global-scale, lower-carbon energy system is expensive and difficult, and affects nearly every aspect of human activity. Innovations in the production and use of energy may offer cheaper, cleaner energyโ€”but will require the right mix of policy incentives, research programs, and deployment efforts. These articles tackle the energy challenge from a huge variety of angles, offering insightful proposals for a more sustainable global energy system.
