The RETScreen Clean Energy Project Analysis Software is a unique decision support tool developed with the contribution of numerous experts from government, industry, and academia. The software, provided free-of-charge, can be used worldwide to evaluate the energy production and savings, costs, emission reductions, financial viability and risk for various types of Renewable-energy and Energy-efficient Technologies (RETs). The software (available in multiple languages) also includes product, project, hydrology and climate databases, a detailed user manual, and a case study based college/university-level training course, including an engineering e-textbook.

RETScreen 4, a major new edition of the RETScreen software, helps rapidly evaluate whether a proposed clean energy project makes sense and is worth further consideration. This presentation introduces RETScreen 4, highlights its new features, and describes the RETScreen approach to project analysis.
