Since the concept of efficiency is not appropriate for the loss analysis of generating running condition of generation,the minimum total loss is taken as the optimal objective for voltage regulation method which is analyzed and contrasted with several other energy saving approaches.

The energy-saving ways of building air-conditioning system are over-viewed in terms of building envelope design,air-conditioning system design,application of new style cold and heat sources,operation management and so on.

The problems existing in energy consumption management and the energy-saving ways are discussed.
