Computer program helps value greenhouse gas emissions

Natural Resources Canada released the latest version of its RETScreen wind project analysis software at the conference. The upgrade links users to the National Aeronautic and Space Administration's global satellite weather database and incorporates a wind speed database compiled from 1000 ground stations around the world. The RETScreen team also worked with the UN's Environmental Program to develop a greenhouse gas emissions worksheet, which allows users to estimate emission reductions associated with a project and assign them a market value for inclusion in the financial analysis. An on-line user's manual and a product database with links to the web sites of manufacturers have also been added. The software, designed to help decision makers rapidly identify and evaluate the most viable opportunities for renewable energy, is available free over the Internet. It has been licensed by over 10,000 users in 170 countries.
