of new generating plants involves such current issues as air pollution, wa-
ter pollution, materials handling (particularly with nuclear plants), fuel
availability, and federal, state, and municipal regulations.
These issues have brought about some recent thought about the con-
struction of “energy centers.” Such systems would be larger and more
standardized than the power plants of today. This concept would reduce
the number of plants that are needed to produce a specific quantity of elec-
