I guess you never been in a data center in the last 10 years. All modern DCs run on DC power because stepping down voltage is easy and 95%+ efficient. Why do

I guess you never been in a data center in the last 10 years. All modern DCs run on DC power because stepping down voltage is easy and 95%+ efficient. Why do we backhaul electricity across the country by DC and convert into AC to our house and then back into DC for our stuff? Add renewable energy generation like solar cells and battery storage and AC makes no sense.
Theres a reason why china is spinning up DC power grids while posts like mine get bashed on.
- joenathanone 3y agoData Centers that use DC still have AC to the racks, then a UPS or similar device converts to DC and distributes to the equipment on the rack. DC is inefficient for long distance, unless you are talking HVDC which is another story and it is disingenuous to act like they are comparable.
