One major correction to the above

So the one thing I am missing is that 1kw of energy generates 4kw of air conditioning load, if you are in a climate where you are running air conditioning you need to multiply the above numbers. Let's say you are running air conditioning for 6 months of the year you need to multiply the above numbers by 2.

Unless you've got a roomful of computers you need to cool, you can pretty much ignore this part. More than likely, you'll be turning on the AC anyway so you can keep cool.

Yes, but every little additional load of heat generates a little additional load of cooling, even if you can't measure it. And ultimately you still have to pay for it.

Usually the air conditioning units have a coefficient of performance of at least 2 or 3. This means that if you generate 1KWh of heat you need 500Wh or less for the air conditioning to move the heat out of the room and if you use the air conditioning for 6 month a year you need to multiply with 1.25.
