Finland's underground data centers heat entire city blocks using server waste heat
In Finland, several data-centres now feed their waste heat into municipal district-heating networks instead of simply dumping it into the air. For example, waste heat generated by data-centre cooling is captured and transferred into the district-heating grid, providing carbon-neutral heat to thousands of homes and public buildings. This reuse of thermal energy helps reduce reliance on fossil-fuel heating, cuts emissions, and turns the by-product heat from digital infrastructure into a genuine resource rather than waste.

@NotAlexMoraes@joedollarbills@ellymelly 1. "China" refers to a large number of people; more than in "The West".
2. They make so much stuff for the West - certainly stop buying this crap.
3. What should activists do? Fly there to protest? We all need to improve locally.
4. We don't say China's great, just buy their crap
@joedollarbills@ellymelly So this whole topic is about quantity- it's not a qualitative issue where any amount of CO2 is equally bad, and certainly not carbon in solid forms such as amino acid molecules and fats.
@ABridgen I didn't know Britain was doing that - that's awesome to give an idea of how much carbon you produce! Shame some Brits want to be infinitely egregious and create/spread false information.
