An independent impact study estimated that by 2013, the use of the RETScreen software had been responsible, worldwide, for over $8 billion in user transaction cost savings, 20 MT per year of greenhouse gas emissions reductions, and has enabled at least 24 GW of installed clean energy capacity.
Nezavisnom studijom uticaja procenjeno je da je do 2013. godine upotreba softvera RETScreen omogućila, širom sveta, uštedu od preko osam milijardi dolara na transakcijskim troškovima korisnika, smanjenje emisije gasova staklene bašte za 20 MT godišnje, a instalirano je najmanje 24 GW kapaciteta čiste energije.
