Power delivered to the load is the main required energy input to the
generator.

However,
 losses in the delivery equipment and the generation equipment is due to the
current or VA required to deliver power to the load. eg. Heating in the
windings of the generator is due to the current passing through the windings
and is not related to the usage (watts) the load makes from the source.

I don't believe I've ever encountered this claim before but it's been about
50 years since I learned the fundamentals. Still, I don't recall anything
like this and this PDF from Cummins Power Generation "appears" to say
exactly the opposite.

http://www.cumminspower.com/www/literature/technicalpapers/PT-6004-PowerFactorTests-en.pdf

Cummins says, "A generator operating at rated kW at 0.8 power factor lagging
load requires more kW from the engine than when running at rated kW on a
resistive load bank. This is due to a change in alternator efficiency and
will result in increased operating temperatures and fuel consumption."
