IEA report "Tracking Clean Energy Progress 2015"

The report of the International Energy Agency (IEA) "Tracking Clean Energy Progress 2015" checks up on progress in the development and deployment of key clean energy technologies. Each technology and sector is examined against interim 2025 targets in the IEA 2015 Energy Technology Perspectives 2°C scenario, which lays out pathways to a sustainable energy system in 2050. The term "clean energy", however, includes non-renewable technologies, e.g. nuclear power or carbon capture and storage of fossil carbon emissions.
