This document assesses the progress made in developing methodologies and in quantifying the externalities associated with incremental investments in electric power production for wind energy and hydroelectric power. The wind fuel cycle has been assessed using two reference sites in the United Kingdom and the hydroelectric fuel cycle using a reference site in Norway. A methodology for the calculation of damages due to the impacts of wind energy and hydroelectric power generation has been successfully developed. The damage function approach has been successfully applied to estimate most of the priority impact pathways of both fuel cycles. It is concluded that siting of wind turbines is the key issue in determining the level of environmental externalities. With correctly sited turbines, wind energy is largely free of environmental impacts which have long-term, inter-generational or serious ecological impacts. For the hydro fuel cycle, expert estimates have been used to estimate impacts in the absence of general dose-response functions. The study has also assessed a number of additional impacts including employment effects and amenity impacts. In order to calculate the latter, a new site- and project-specific environmental valuation study has been conducted within the valuation phase.
