With regards to turning it back into electricity, that is not feasible due to the way entropy works. You would just generate more heat than electricity in the process. However, there are schemes to heat homes with waste heat from data centers. I know for a while, some crypto mining companies rented space in residential structures and sold the heat to the building. Probably a better alternative would be geothermal air conditioning. A heat pump's efficiency is related to the difference in temperature. Utilizing the constant temperature of the earth's crust, you can maintain an extremely efficient air conditioner. Iron Mountain does this. https://betterbuildingssolutioncenter.energy.gov/showcase-projects/iron-mountain-data-centers-geothermal-cooling-system https://betterbuildingssolutioncenter.energy.gov/showcase-pr...
