Finally some rational thought. Here is a statistic from wikipedia that 
comes close to what you want to know:


(This graphs shows world-wide energy usage in terawatts (10^12 watts).

1 terawatt = 3.41 teraBTU

BTW, volcanos do not get their power from burning fossil fuels. Their 
biggest environmental impact is the particulate they spew into the air.
(See recent airspace closures in Europe).
