Abstract Effective approaches to the management of plutonium and highly enriched uranium (HEU)-the essential ingredients of nuclear weapons-are fundamental to controlling nuclear proliferation and providing the basis for deep, transparent, and irreversible reductions in nuclear weapons...

Energy-technology innovation (ETI) is the set of processes leading to new or improved energy technologies that can augment energy resources; enhance the quality of energy services; and reduce the economic, environmental, or political costs associated with energy supply and use. Advances achieved...

The environmental costs of energy supply have been rising, reinforcing the effect of increased monetary costs in creating incentives for increasing the efficiency with which energy is used. Quantifying these environmental costs is difficult, but it is instructive to try. The estimates presented...
