The IEA’s annual flagship publication, the “World Energy Outlook 2011,” stresses that increasing investments in high-carbon infrastructure are making the 2°C international climate change goal more challenging and expensive to meet.

In this new report IEA provides an overview of clean energy and energy efficiency technology deployment and summarises support policies in place across G-20 countries.

As energy is the source of all life, so modern energy can be the source of a better life for all. The International Energy Agency’s World Energy Outlook (WEO) has focused attention on modern energy access for a decade, providing the international community with quantitative, objective analysis.

This annual IEA report contains estimates of CO2 emissions by country from 1971 to 2009, selected indicators such as CO2/GDP, CO2/capita, CO2/TPES and CO2/kWh & CO2 emissions from international marine and aviation bunkers.

Coal is an important source of energy for the world, particularly for power generation. To meet the growth in demand for energy over the past decade, the contribution from coal has exceeded that of any other energy source. Additionally, coal has contributed almost half of total growth in electricity over the past decade.

Key World Energy Statistics produced by the IEA contains timely, clearly-presented data on supply, transformation and consumption of all major energy sources.

A new technology roadmap on Carbon Capture and Storage in Industrial Applications shows that carbon capture and storage (CCS) has the potential to reduce CO2 emissions from industrial applications by 4 gigatonnes in 2050.

Meeting the enormous challenge of decarbonising world energy systems will require a rapid expansion of investment in clean technologies on a global scale. Mobilising these resources will be a daunting task, and it is important to undertake the transition at the lowest cost possible.

Increased focus has been placed on the issues of energy access and energy poverty over the last number of years, most notably indicated by the United Nations (UN) declaring 2012 as the “International Year of Sustainable Energy for All”.

This paper aims to examine the justification for specific energy efficiency policies in economies with carbon pricing in place. The paper begins with an inventory of existing market failures that attempt to explain the limited uptake of energy efficiency.
