A methodical, step-by-step account of big city power distribution as it is accomplished in New York by the Consolidated Edison Company forms a reliable if dry introductory survey for interested readers. Topics covered include first, the immense job of servicing a huge city. Breaking this down there is the generating plant outside the city; the plant's control system; distribution grids and transformers; currents and how generators produce energy; gas; emergency crews; electricity and safety at home; how a meter works; and rural distribution. A last chapter presents vocational opportunities.
