Questions about the reliability, affordability and sustainability of our energy future often boil down to questions about investment. But are investors ready to commit capital in a fast-changing energy world?

This publication represents a continuation of efforts by IEA to provide strategic, economic and policy analysis on various aspects of carbon capture and storage. CCS has suffered from a lack of attention by public and policy-makers over the past several years.

Chinese NOCs first ventured overseas to invest in oil and gas production more than 20 years ago. Today, they have emerged to become international players with activities spreading across more than 40 countries and producing 2.5 million barrels of oil equivalent per day (mboe/d) of oil and gas outside of China.

Co-generation technologies and efficient DHC networks offer significant environmental and energy security benefits, and can serve as flexible tools to bridge electrical and thermal energy systems. Yet despite these advantages, and successful implementation in some countries, to date, global deployment has been limited.

Energy efficiency is high on the political agenda as governments seek to reduce wasteful energy consumption, strengthen energy security and cut greenhouse gas emissions. However, the lack of data for developing proper indicators to measure energy efficiency often prevents countries from transforming declarations into actions.

Coal is the principal fuel for the global generation of electrical power. It is the leading source of power generation in OECD countries and the dominant fuel source behind economic growth in non-OECD countries.

Energy efficiency is a growing policy priority for many countries around the world. It is widely recognised as the most cost-effective and readily available means to address numerous energy-related issues, including energy security, the social and economic impacts of high energy prices and concerns about climate change.

Tracking Clean Energy Progress 2014 examines progress in the development and deployment of key clean energy technologies.

This new paper published by the International Energy Agency (IEA) highlights some of the dynamics of renewable energy use for heat in different markets, the status of different technologies and policy measures to efficiently promote renewable heat, and provides an outlook for the potential role of renewable heat in the medium- and long-term.

According to this new IEA report China, India, the European Union and the United States alone should invest at least USD 380 billion in new electricity storage capacity by 2050 to support decarbonisation.
