I've recently asked a couple of questions on this subject, and
larre-ga provided excellent answers.  So I was wondering if larre-ga
could answer these questions, also:  1) What % of California's
electricity generation is provided through fossil fuels?  2) How much
and what type of fuel do these generators use to produce the
electricity, i.e. bunker fuel or diesel?

residual fuel oil (such as No. 6 Fuel Oil). The amount of sulfur
varies with product specification.

Fuel Oil, No. 5:

A complex combination of heavy (high boiling point) petroleum
hydrocarbons. The amount of sulfur varies with product specification.

Fuel Oil, No. 6:

A complex combination of heavy (high boiling point) petroleum
hydrocarbons. The amount of sulfur varies with product specification.
Hydrogen Sulfide (H2S) may be present in trace quantities (by weight).

Synonyms for Fuel Oil #6 include Bunker Oil.
