Yes, of course. I provided references to most of those numbers in my earlier post. Here are the rest. Again, if anyone feels I've glossed over something important, let me know. Also, just like before, this system won't let me post links yet, so I have removed the WWW to get the links through. Just add to the front of the links to reconstitute.

Percent of coal and other energy sources used to make power

Virginia energy patterns and trends

Chart at energy.vt.edu/vept/electric/netgeneration.asp
or energy.vt.edu/vept/electric/netgeneration_year.asp?yr=2004
(says coal plus oil percent = about 50%)

Efficiency of coal and gas plants:
----------------------------------------------------
ieej.or.jp/aperc/pdf/GRID_COMBINED_DRAFT.pdf
(page 36, footnote 50, coal plants are 37% efficient)
(gas plants are 48% efficient)
National renewable energy Laboratory
healthgoods.com/Education/Energy_Information/General_Energy_Information/fossil_fuel%20coal.htm
says average coal plant (back in 1992) is 33% efficient - but new technology plants are up to 85% efficient.

EV Regen braking benefits
----------------------
onechip.co.uk/simon/electric/regen.html
Says 5 to 10% increase in range from EV regen braking.
ihpva.org/pipermail/velomobile/2000-March/000016.html
Claims 22% increase in range (using a trike, a very efficient electric vehicle)
rmi.org/sitepages/pid433.php
says 30% of energy is typically lost to braking
en.wikipedia.org/wiki/Regenerative_braking
says regen braking has 31.3% efficiency; combined with above figure for 30% energy loss to braking, implies 9.4% increase in energy efficiency.

San Francisco Chronicle news article

"We get our gasoline barged up to us at a cost of 3 cents a gallon versus the 10 cents a gallon cost of trucking" (this was from 2001, may be higher now.)
Federal trade Commission
ftc.gov/bc/gasconf/comments2/jacobsstevee.pdf
"Cost of Transporting Gasoline 1000 miles. Cents/Gallon. Pipeline. 1.5 - 2.5. Barge. 4 - 5. Truck. 30 - 40."
(this was from 2002, may be higher now.)
