This tends to be more energy heavy then when a compiled language is used. The compilation is then only done once, saving on resources. + +## Solution + +Use compiled languages (like Go, Rust, Java or others) whenever possible or compile interpreted languages. + + +## SCI Impact + +`SCI = (E * I) + M per R` +[Software Carbon Intensity Spec](https://grnsft.org/sci) + +Concerning the SCI equation, use compiled languages will impact as follows: + +- `E`: Running compiled binaries is more energy efficient and uses less energy which outweighs the energy consumed in compiling it to binary upfront +- `M`: The embodied carbon emissions will be reduced, as compiled binaries tend to be smaller then the sources they are compiled from + +## Assumptions + +- There is the assumption that the execution environment allows usage of compiled languages, this is not always the case (for example web browsers) +- Use benchmarks to determine if the application use case benefits from using a compiled language. + +## Considerations + +- Some interpreted languages provide ways to be compiled into binary (for example GraalVM for Java, Python and more) +- Consider factoring in compile time when doing benchmarks + +## References + +- [One Carbon intensity benchmark](https://greenlab.di.uminho.pt/wp-content/uploads/2017/10/sleFinal.pdf) +
