Have you seen the price of diesel? It's about 10% more than gasoline.

Which means it still wins on energy per gallon, as it has almost 50%
more BTUs/gallon. And a diesel generator making 50% power burns pretty
nearly 50% the fuel it does at full power, while a gasoline/NG/propane
unit is considerably worse (fuel/kwh) at partial power (don't have my
manual handy, but fuel consumption at half load is considerably more
than 1/2 fuel consumption at full load).

One can more commonly/easily get off-road (no road tax, cheaper) diesel
than off-road gasoline, at least in the US.
