Can GenAI Help Reduce Energy Used by Java Code?

Some recent studies show that IT is emitting more CO2 than civil aviation! As software developers, there is something we can do: optimising our code. Making our code run more efficiently should reduce the carbon footprint of IT. It will consume less CPU, RAM, disk, and network. Hardware being powered by electricity, these optimisations should reduce our electricity bills and lower emissions due to generation of that electricity. Optimised software also extends hardware lifespan by reducing the need for upgrades, diminishing the embodied carbon from manufacturing and avoiding raw material extraction (e.g., rare earths mining).
