NVIDIA has just announced a highly innovative approach to tackling carbon emissions in the world with their CNHC (Carbon Negative Heating Consortium) initiative and their first HeatForce (HEATFORCE?) Mark I generation of crypto-mining smart heaters. The idea is that instead of using your dumb 1500 watt space heater, why not swap in NVIDIA's smart heater which can (depending on your choice) either give you carbon zero or carbon negativity.

NVIDIA starts with talking about the "Wasted Work" problem. Homes are heated either using gas or electric heaters (and rarely, heat pumps). Considering heat is the end product of pretty much all work done (computations) anyways, this is energy that could have been used to do valuable calculations before being wasted as heat. Based on the profitability rates of today's crypto, NVIDIA estimates that 1500 watts is sufficient to generate roughly $500 in profits (after accounting for your energy bill).
