composition, heat transfer and mechanical energy generation devices, use of a composition, blowing agent, foam, and methods for cooling and heating an article, for extracting a substance from biomass and a material, for cleaning an article, for refit a heat transfer device to reduce the environmental impact to prepare a composition and / or heat transfer device, and to generate greenhouse gas emission credit. The invention provides a heat transfer composition of essentially about 60 to about 85 wt.% trans-1,3,3,3-tetrafluoropropene (r-1234ze (e)) and about 40 wt.%. fluoroethane (r-161). The invention also provides a heat transfer composition comprising r-1234ze (e), r-161 and 1,1,1,2-tetrafluoroethane (r-134a).
