The RETScreen International Clean Energy Decision Support Centre  seeks to build the capacity of planners, decision-makers and industry to implement renewable energy, cogeneration and energy efficiency projects. This objective is achieved by: developing decision-making tools (i.e. RETScreen Software) that reduce the cost of pre-feasibility studies; disseminating knowledge to help people make better decisions; and by training people to better analyse the technical and financial viability of possible projects.

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 online user manual, and a case study based college/university-level training course, including an engineering e-textbook.

RETScreen International is managed under the leadership and ongoing financial support of Natural Resources Canada (NRCan )'s CanmetENERGY. RETScreen is developed by a core team  at CanmetENERGY in collaboration  with a number of other government and multilateral organisations, and with technical support from a large network of experts  from industry, government and academia.
