2. Distributed generation: a report on its current status
Rising fuel prices have dealt a setback to the distributed generation movement and its advocacy of on-site power, but there are still a number geographic regions and types of facilities where the technology makes sense. Also, a survey of on-site power projects reveals a trend toward alternative energy sources.
