WEO 2003 is the World Energy Investment Outlook (Insights). No world solar PV or wind capacity or generation projection was found in the text (searched pdftotext output for wind, solar, photovoltaic with GW and TWh). It states a PV capital cost decline of 63% to 2030 (chapter on power investment); not captured because it is a cost, not deployment, figure.
