In the 1st lecture, I mentioned that some computing environments, such as cloud-based platforms, are very concerned about their energy consumption (at least to minimise costs), and their environmental impact.
Here's an interesting article on that topic:

"Choosing a programming language is a challenging task. What matters is not only whether the developers learn it quickly, but also what they can code in it and whether it is developed. Although until now, the main focus has been primarily on creating fast programs, and performance in software languages has, in almost all cases, been synonymous with fast execution time, today, it also matters energy consumption. Hence, the growing concern about the energy efficiency of computers forces an appropriate approach to programming. So, which of the currently available programming languages can be called the fastest and most energy efficient?"
