The IEA projects global primary energy demand could grow by 55% from 2005 to 2030, raising serious energy security and environmental sustainability concerns. How will we meet energy demand? How will we mitigate the resulting 57% increase in carbon dioxide emissions?

The International Energy Agency (IEA) is developing in-depth indicators of energy use, efficiency trends and CO2 emissions. This latest publication provides a summary of the key results of the indicators work so far and shows how this can be used to identify the factors driving and restraining the demand for energy. Also explains why there are differences in energy intensities amongst countries.

In 1997 the IEA produced a handy, pocket-sized summary of key energy data. This new edition responds to the enormously positive reaction to the books since then. Key World Energy Statistics from the IEA contains timely, clearly-presented data on the supply, transformation and consumption of all major energy sources.

This paper focuses specifically on measures to increase the flexibility of power systems

This paper presents a set of indicators that are used to analyse the energy efficiency of electricity production from fossil fuels on a global level and for a number of key countries and regions. The analysis is based on IEA statistics and includes public electricity plants and public CHP plants.

The aim of this paper is to describe and analyse current approaches to encourage energy efficiency in building codes for new buildings. Based on this analysis the paper enumerates policy recommendations for enhancing how energy efficiency is addressed in building codes and other policies for new buildings. This paper forms part of the IEA work for the G8 Gleneagles Plan of Action.

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.
