This is not much of a question, more like a possible way to get some more attention to the Julia language. Everybody is talking about we need to save the planet and use less energy. I think it could be a great way to promote the Julia language. Compare the power consumption between let say, java/j…

I wouldn’t feel too bad about CI. Let’s do a bit of fun order of magnitude analysis! Your average laptop draws ten to a few tens of Watts at idle. Let’s overestimate at 100W at max load. My typical packages take less than a minute to run through tests. Arguably for a good dev experience it should …

I’m not so sure about your calculations though - if that is so, why does mining cryptocurrencies use soooo much energy (more than some countries) Server farms do use quite a bit of energy - so if you can get 10x - 100x more work done running Julia code rather than say, Python, wouldn’t that make a …

I think it absolutely makes sense to compare domains quantitatively, in terms of making life decisions “should I participate in this or that activity”. If choosing Julia vs some other language is 1% or less of the energy used just to keep me living a normal life, then there’s no reason to waste tim…

I agree when considering my general choice of an activity, 1% is not that much. But if I can save 0.8% of my energy consumption just by switching language, and still accomplish my goals, that’s also very relevant! I think that’s the core question of this thread…

To get back to the original topic here (which was a nice and positive message, thanks :slight_smile: ) I think it will be extremely difficult to quantitatively show that Julia saves energy. Things to consider: Julia should be used “in production” as part of a large, potentially ongoing computatio…

[image] How to measure energy consumption of computations? General Usage Developing models and running simulations is a core activity of our research department. Faster languages (Julia) and better algorithms result typically not in less computation, but in more ambitious …

This has been discussed here some times. Although I agree mostly with the points of @c42f that it is not clear if these measures actually mean anything for the real-world use of energy in computing, there are these two studies: In this one Julia is not initially present, but somewhere there one can…

Perhaps that’s not what this post is about, but it seems worthwhile to mention that Julia is very much used in green tech, from climate modelling to energy grid optimization . We’re using it as well in an industrial setting to reduce our client’s energy consumption. Those initiatives can move the nee…
