Choose a power efficient programming language 

Programming languages have varying levels of efficiency when it comes to power consumption. Some languages, such as C and C++, are known for their low-level, close-to-hardware nature, which allows for fine-grained control over system resources and can result in more power-efficient code. On the other hand, interpreted languages like Python or JavaScript, may have higher levels of abstraction and runtime overhead, which can result in several times higher power consumption, as outlined in this AWS blog.

Modern compilers often provide optimization options that can reduce code size, remove unnecessary computations, and optimize register usage, which can lead to more power-efficient code. For code sections that are executed at a high frequency (or are time sensitive), enabling compiler optimizations, such as loop unrolling, function inlining, and dead code reduction, can result in more efficient code execution and lower power consumption.
