This site and others show 114,000 BTUs per gallon of gasoline (unleaded

Also, light rail doesn't pollute in the city, so it doesn't contribute
as much to local smog. The electricity could be generated by wind,
geothermal, hydroelectric, or coal. If coal, pollution controls are
all at the single point of source.
Last, a lot more effort has gone into making cars more efficient than
has gone into making light rail and trains more efficient, which means
there is a lot of room for improvements. Electrical generation
improvements, including more efficient transformers, transmission
lines, capacitor installations, cogeneration, and distribution voltage
upgrades will continue to improve electrical efficiencies. Here's a
link that describes a lot of the improvements in electricity
generation, and points out that there's a lot of room for improvement:
