2.2.2 Methodology on Potential Energy-Savings Analysis
The potential energy-savings is based on the improvement of energy intensity of
GDP or energy consumption per unit GDP, which is the ratio of energy consump-
tion to GDP.

Various factors can affect energy intensity, including economic and social
factors, as well as the energy consumption structure and local condition such as
climate and land area [

].
Many incomparable elements could impact energy intensity among different
countries and regions due to a different economic development phase, energy
consumption structure, natural conditions and even the foreign exchange rate.
Two approaches could be taken to improve energy efficiency or energy
savings—structure optimization and technical improvements.
