Which Programming Languages Use the Least Electricity? (2018)

And while Fortran was the second most energy efficient language for this test, it also dropped a full six positions when the results were instead sorted by execution time. So while there’s still a common belief that energy consumption goes down when programs run faster, the researchers state unequivocally that “a faster language is not always the most energy efficient.” “It is clear that different programming paradigms and even languages within the same paradigm have a completely different impact on energy consumption, time, and memory,” the researchers write.
