The RETScreen Wind Energy Project Model can be used world-wide to easily evaluate the energy production, life-cycle costs and greenhouse gas emissions reduction for central-grid, isolated-grid and off-grid wind energy projects, ranging in size from large scale multi-turbine wind farms to small scale single-turbine wind-diesel hybrid systems.

The software also includes product and weather databases and an online manual. Version 3.0 upgrades include a Metric/Imperial unit switch; updated product data; an enhanced GHG model to account for emerging rules under the Kyoto Protocol; a Sensitivity & Risk Analysis worksheet; and the ability for users to now evaluate wind projects using wind power density data (in addition to wind speed data).
