Abstract

The California power crisis and September 11 terrorist attacks of 2001 have reinvigorated debate over the electric power system’s vulnerabilities. But beyond the threat of terrorist attacks on nuclear power stations and the issue of insufficient power, a central, fossil-, and nuclear-based electric power infrastructure carries additional risks. These include aging transmission and distribution systems, environmental impacts, and the failure to bring power to 1.8 billion people in the developing world. Such vulnerabilities could be lessened through small-scale, decentralized technologies. These micropower units exhibit many hidden benefits, such as improved fuel supply diversity, strengthened transmission and distribution systems, and a lower ecological footprint. Micropower is emerging in two niches: developed nations where businesses place a premium on power reliability and developing-nation regions where small-scale power is the most economical means of alleviating power poverty. But broader deployment of micropower requires removal of market barriers and greater use of innovative financing.
