How about dirtier instead of cleaner. Cleaner need not mean clean. Even Solar Power isn't clean (Manufacture of photovoltaic cells requires potentially toxic metals such as lead, mercury and cadmium and produces carbon dioxide and and in large scale Solar Power facilities use massive amounts of water).

But the electric grid is about 50% coal, 1% Oil, 22% Natural Gas, 19% nuke, 6% Hydro, and 3% renewable. In total it is cleaner, er... less dirty than petroleum when burned in your average ICE. Plus we can make electricity less dirty by changing the sources (more wind, less coal). You can't change the source of a diesel engine as easily (pull engine out, put in new engine).
