Climate  change analysis and  environmental analysis

• The climate section of the WEO-2011 focuses on the 450 Scenario
  For a full description of the policy framework underlying this scenario
• Emissions  of Air Pollutants for the WEO-2011 Energy Scenarios
  This report examines global emissions of major air pollutants (SO2, NOx, PM2.5) resulting from energy scenarios developed for the WEO-2011, which have been estimated using the IIASA GAINS model. The report is available here.

Power sector analysis

• T&D infrastructure
  A considerable proportion of the investment in the electricity sector is for transmission and distribution networks. WEO-2011 contains an analysis of the drivers of these costs and how these are likely to develop over time. For a description of the methodology used for this analysis.

• Implications  of increasing renewables-based capacity
  WEO-2011 discusses the implications of variable renewables for power systems, and in particular the capacity credit that can be assigned to these technologies.  For a description of the methodology used for this analysis, click here.

Energy subsidies and support

• Fossil-fuels
  Fossil-fuel subsidies are most often wasteful, inefficient and costly. WEO-2011 updates its estimate of subsidies for fossil fuel consumption. For a description of the methodology used for this analysis, click here.
• Renewables
  Renewable energy sources are used in several sectors. In many cases they are still not competitive and require subsidies to enhance and accelerate their deployment. Subsidies for renewable-based electricity generation and biofuels for transport have been estimated in WEO-2011. For a description of the methodology used for this analysis.
