In almost all selected industrial activities, most of the energy was devoted to heat production, except in manufacture of basic metals (aluminium), where the most energy was devoted to electrochemical processes.
Skoraj v vseh izbranih dejavnostih je bilo največ energije namenjene za proizvodnjo toplote. Izjema je bil oddelek proizvodnja kovin (aluminija), kjer je bilo največ energije namenjene za elektrokemične procese.
