Table 2 The contrast between the energy efficiency and rationalization [33]

• Energy efficiency depends on the use of advanced technology to reduce energy use, conserve the same much performance.

• Focus on the performance of equipment and machinery.

• Replace the traditional light bulbs with a more efficient (LED) as well as home thermal insulation and the use of energy-saving appliances.

• Rationalizing consumption depends on individual behavior, which leads ultimately to reduce energy consumption.

• Focus on the performance of human behavior.

• Switch off the light when out of the room.
