Answer 1

Answer:

Efficient energy use, sometimes simply called energy efficiency, is the goal to reduce the amount of energy required to provide products and services. For example, insulating a building allows it to use less heating and cooling energy to achieve and maintain a thermal comfort

Answer 2

Answer:-

• Efficient energy use, sometimes simply called energy efficiency, is the goal to reduce the amount of energy required to provide products and services. For example, insulating a building allows it to use less heating and cooling energy to achieve and maintain a thermal comfort.

• Energy efficiency is a means of measuring the energy-expenditure required to achieve a certain benefit. The lower the losses in energy to achieve a specific purpose are, the higher is the degree of energy efficiency.
