individual industries will use energy as efficiently as it is economical to do so, and there are several incentives to improve the efficiency of energy consumption. To illustrate, consider the selection of a new water pump. The pump is to operate 800 hours per year. Pump a cost $1900, has an overall efficiency of 81.2% and it delivers 10.6 hp. The other available alternative, pump B, cost $900, has an overall efficiency of 44.45% and delivers 12.4 hp. Both pumps...
