Tracking Clean Energy Progress 2014 examines progress in the development and deployment of key clean energy technologies. This Energy Technology Perspectives 2014 (ETP 2014) excerpt tracks each technology and sector against interim 2025 targets in the IEA 2014 Energy Technology Perspectives 2°C scenario, which lays out pathways to a sustainable energy system in 2050. Deployment of solar photovoltaics (PV), onshore wind and electric vehicles (EVs) is still increasing rapidly, but their growth rates are slowing. Growth of coal-fired power generation exceeds that of all non-fossil fuels combined. Nuclear power generation is stagnating. Development of carbon capture and storage (CCS) remains too slow. These trends reflect inadequate political and financial commitment to long-term sustainability of the global energy system. Tracking Clean Energy Progress 2014 provides, together with ETP 2014, specific recommendations to governments on how to scale up deployment of these key technologies toward a secure, clean and competitive energy future.
