‌Tracking Clean Energy Progress 2013 examines progress in the development and deployment of key clean energy technologies. Each technology and sector is tracked against interim 2020 targets in the IEA 2012 Energy Technology Perspectives 2°C scenario, which lays out pathways to a sustainable energy system in 2050.

Stark message emerge: progress has not been fast enough; large market failures and preventing clean energy solutions from being taken up; considerable energy efficiency remains untapped; policies need to better address the energy system as a whole; and energy-related research, development and demonstration need to accelerate.

Alongside these grim conclusions there is positive news. In 2012, hybrid-electric vehicle sales passed the 1 million mark. Solar photovoltaic systems were being installed at a record pace. The costs of most clean energy technologies fell more rapidly than anticipated.

The new report provides targeted recommendations to policymakers on how to scale up deployment of these key technologies.
