IEA (2012), "Tracking Clean Energy Progress 2012", IEA, Paris https://www.iea.org/reports/tracking-clean-energy-progress-2012
Tracking Clean Energy Progress is an early except of the forthcoming Energy Technology Perspectives 2012 (ETP 2012). The report tracks progress in the development and deployment of clean energy and energy efficiency technologies in the power generation, industry, buildings, and transport sectors. Progress is assessed against rates required to achieve a 2°C limit in global temperature rise. The report finds that while some progress has been made, most clean energy technologies are not on track to make their required contribution to reducing CO2 emissions and thereby provide a more secure energy system. It also highlights that getting back on track is possible, if timely and significant policy action is taken. Progress is evaluated by analysis in three main areas: technology progress (using data on technology performance, technology cost and public spending on research, development & demonstration); market creation (using data on government policies and targets, and private investment); and technology penetration (using data on technology deployment rates, share in the overall energy mix and global distribution of technologies).
