I finished reading World Wide Waste by Gerry McGovern. I'd consider it essential reading for anyone working with computers!

It's well cited (though I still need to check those citations) & uses maths effectively to make it's point.
That computers + (surveillance) capitalism is actually worse for the environment than the predigital era. That we can and must move slow and fix things, and fund that vital work directly.
