According to Winston Saunders
Not only should all energy that computes heat as little as possible, but all energy that heats should also compute as much as possible.
For instance, near Helsinki’s harbor there’s a data center under the beautiful Orthodox Church which provides some residential district heating. Presumably providing heating in that case offsets the energy costs of the data center.
So is there a business model where providing a compute resource can offset the operating costs of my heater?
For the problems of making this into a business, see this comment by Barry Rountree.
This is yet another case where a carbon tax could help rationalize the economy.
