  "... It is argued that power-efficient hardware is fundamentally 
   limited by voltage scaling, which can be achieved only by 
   blurring the boundaries between devices, circuits, and systems 
   and cannot be realized by addressing any one area alone. By 
   simultaneously considering all three perspectives, the major 
   issues involved in improving power efficiency in light of 
   performance and area  constraints are identified. Solutions for 
   the critical elements of a practical computing system are 
   discussed, including the underlying logic device, associated 
   cache memory, off-chip interconnect, and power delivery system. 
   The IBM Blue Gene system is then presented as a case study to 
   exemplify several proposed directions. Going forward, further 
   power reduction may demand radical changes in device technologies 
   and computer architecture; hence, a few such promising methods 
   are briefly considered."
