In a hot climate where people overwhelmingly are using residential air conditioning, the power used by the data equipment is dwarfed by the air conditioning needed to keep the electronics from overheating. Sometimes not even such hot climates. In an indoor insulated environment all electrical equipment produces heat very efficiently when it runs and its Wattage rating can give you an idea of the maximum heat that might be seen. Appropriate A/C will be rated to remove the nominal amount of heat, often not needing to handle the absolute maximum. On the A/C the high amperage refrigerant compressor/condenser unit, which can only do its job outdoors, and the much more economically operated air circulation motor are drawing electricity and producing additional heat of their own, but ideally they are well separated from having their heat enter the indoor space, by proper location, piping, and ducting. Anyway, the electrical cooling does not work as efficiently as the the electrical heating so you pay more to cool the gear than it costs to run it.
