Worldwide trends in energy use and efficiency: key insights from IEA indicator analysis

Governments in many countries are increasingly aware of the urgent need to make better use of the world's energy resources. Improved energy efficiency is often the most economic and readily available means of improving energy security and reducing greenhouse gas emissions. To support better energy efficiency policy-making and evaluation, the International Energy Agency is developing in-depth indicators of energy use, efficiency trends and CO2 emissions. This publication provides a summary of the key results of the indicators work so far. It shows how indicators can be used to identify the factors driving and restraining the demand for energy, explains why there are differences in energy intensities amongst countries, and quantifies how the introduction of best available technology can help reduce energy use
