C++, C#, Rust or Python - Which is the Best Choice for Low Energy Consumption?
summary
Reproduces benchmarks for Monte Carlo pi with 10 million samples and an Adler‑32 checksum on 50 MB, measures energy via Code Carbon (RAPL/Intel PCM fallback) on WSL, and publishes code on GitHub. Results show compiled languages like C/C++/Rust use the least energy while Python uses the most, energy correlates with runtime not memory, per‑run variability is ~±0.5 normalized units, and moving from Germany to Norway cuts CO2 by about a factor of 10.
