The RETScreen Software Wind Power Model can be used worldwide to evaluate the energy production and savings, costs, emission reductions, financial viability and risk 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 (available in multiple languages) also includes product, project and climate databases, a detailed user manual, and links to wind Energy resource maps.
