Setting energy efficiency standards for electrical equipment could have a huge impact on the world’s power sector. A large number of power plants could be switched off if strict technical standards were brought into force. The table below provides an overview of the theoretical potential for using efficiency standards based on currently available technology.

The Energy [R]evolution scenario has not been calculated on the basis of this potential. However, this overview illustrates how many power plants producing electricity would not be needed if all global appliances were brought up to the highest efficiency standards.
note BY 2050, STRICT ENERGY EFFICIENCY STANDARDS, WOULD MEAN ALL GLOBAL HOUSEHOLDS COULD SAVE OVER 4,000 TWH COMPARED TO THE REFERENCE SCENARIO. THIS WOULD TAKE OVER 570 COAL POWER PLANTS OFF THE GRID.
