Bitcoin heat recycling is now recognized both in the energy sector and independent reports as a way to efficiently deliver electrical heat in a low carbon manner
"Bitcoin mining can be a practical way of cutting carbon and costs while keeping communities warm"

Context:
Two months after Cambridge released a study showing the decarbonizing potential of Bitcoin mining, District Energy released is 3rd Quarter Report, and the entire issue is dedicated to using Datacenters, including Bitcoin mining, as a heat source.
Key quotes:
"Electrifying heat production, especially in regions
with low-carbon or renewable electricity, offers one of the most direct and effective ways to reduce emissions from district heating.
Using the heat generated from bitcoin mining could significantly advance this electrification,
transforming digital energy infrastructure into a source of high-temperature, low-carbon heat."
The report specifically mentions the work of
@MARA
, who are now using Bitcoin mining to supply heat to 80,000 residents in Finland (1.6% of the total population)
"MARA estimate that each MW of recycled heat from bitcoin mining results in 455 fewer metric tons of CO2 emissions per year than the average district heating facility in Finland."
This is just one of the ways that Bitcoin mining has been found to reduce carbon emissions and cut energy costs at the same time. For a full report on other ways that Bitcoin achieves these two aims, you can read my full length report. (Link in the comments)
