Collective ownership would likely be the solution there.
Why yes I do believe you are correct. In my opinion Collective Ownership of the means of production would be a great solution here. We could like... Build greenhouses around the data centers! Or even better; Build the greenhouses upwards over the data centers. Five story greenhouse heck yeah.
Or we could just you know... stop using the data centers. :|
p.s Why do we not capture the steam coming out of nuclear reactors cooling towers? I'm to lazy to look it up.
