Re:Invent Here at a depleted AWS Re:invent in Las Vegas, Rust Foundation chairwoman Shane Miller and Tokio project lead Carl Lerche made the case for using Rust to minimize environmental impact, though said its steep learning curve made the task challenging.
Miller is also a senior engineering manager for AWS, and Lerche a principal engineer at the cloud giant.
How can Rust save the planet? The answer is that more efficient code requires fewer resources to run, which means lower energy usage in data centers and also in the environmental impact of manufacturing computing equipment and shipping it around the world.
Shane Miller and Carl Lerche speak on Rust efficiency and safety at this year's AWS Re:invent in Las Vegas
“Data centers consume … 1 per cent of all worldwide energy,” said Miller, though adding that the total energy consumed had changed little in ten years, thanks to technology advances and the fact that cloud tends to reduce the proportion of idle resources.
The second part of the argument is that Rust is among the most efficient programming languages. The source quoted for this is a 2017 paper [PDF] that measured the performance, memory usage, and energy efficiency of 27 programming languages, and placed C as most efficient, but Rust close behind with just three per cent more energy use. Java uses nearly double the energy, C# over three times, and Python over 75 times as much, according to the stidy.
Languages ranked by energy efficiency, according to a 2 ..
