Investment costs in the power generation sector are based on a review of the latest country data available and on assumptions of their evolution over the projection period. They represent over-night costs for all technologies. For renewable sources and for plants fitted with Carbon, Capture and Storage (CCS), the projected investment costs result from the various levels of deployment in the different scenarios. The review also benefitted from the IEA study: Projected Costs of Generating Electricity: 2010 Edition.
Passenger car transport
A comprehensive review of the costs of reducing fuel consumption for various technology options in passenger light duty vehicles (PLDVs) was conducted for the WEO-2009 in collaboration with the Energy Technology Perspectives team of the IEA. The dataset was peer-reviewed by reviewers from industry and the scientific community.
The analysis was conducted by looking into the short-term and long-term maximum potential of reducing fuel consumption relative to a gasoline internal combustion engine (ICE) vehicle that was manufactured in the year 2000 and has a fuel consumption of about 7.2 litres of gasoline per 100 kilometres. The short-term analysis reflects the reduction potentials that can be achieved within 5-10 years from today, whereas long-term improvements could be achieved within the next 20 to 30 years. The details of this analysis covering engine and non-engine improvements on a technology-by-technology basis and details about the costs of various battery types can be found in IEA (2009a, 2009b), and a summary table is provided at the link below. The potentials and costs established in this analysis are the basis of all analysis on the costs of PLDV transport and the marginal costs of abatement in WEO-2011. Differences across scenarios occur as a result of different levels of fuel consumption achieved in the different scenarios.
