As has been pointed out before, more coal workers have died per

Does that include the long term (25 years) effects of both coal as
well as nukes?

BTW, helps to make the case to wean ourselves from fossil fuels as
quickly as possible.

And replace them with what, Lew?
Horses?

Reminds me why the automobile was hailed as the solution to horse
manure pollution in (at least) New York City.

There is nothing in the wings that has near the power and
portability as gasoline. I would add that our problem is that we
are 50 years late deciding to make internal combustion effecent and
clean. But we didn't have the computer technology back then to do
it.

Apart from nuclear, there is water, wind, solar and more renewable
sources. Battery technology is now so far along that even tugboats
are equipped and are saving (in hybrid mode) 40-60% of their diesel
consumption. I'm not that sanguine about the "greenness" of
manufacturing high yield batteries, but that should also improve with
demand. For now, I think the only transportation that would be
difficult to replace is jet planes.


Actually, I think the biggest problem is shipping - freighters.
Dig into that some.

Depending on the size of the ship, nuclear could be an option, although I
don't think any ships apart from navy have been nuclear so far.
