And much more cleanly/efficiently than a small gasoline-powered generator, regardless of the energy source.

Coal-powered steam turbine is not that more efficient than a portable gas generator so considering coal is more carbon-intensive it's actually about the same or even worse in terms of emissions if you consider coal burning also produces mercury. Now nat gas-powered CCGT - different story. Good news is NYC is mostly powered by the latter and there's zero coal.
