The universe's massergy comes in two forms, the dense matter, and the
very-not-dense energy. We use mass (kg) to
count matter, and energy (Joules, J) to
count energy.
Currently in pre-first-draft state...
Notes:
nuclear phase transition requires particle energy order 2 GeV [AmSci '98 SepOct p449]
Right on edge of oom 1e-9 J. If turns out to be <2 GeV, should be 1e-10 J.
I'm not clear on how speculative this model is. Could check this.

nuclear density critical-point 0.05 nucleons/fermi^3 at T of ~14 MeV.

1 jelly donut (JD) = 10^{6} J
1 kWh = 3.6 JD
1 flashlight battery (D cell) = 1.6 × 10^{4} J = 0.016 JD
1 mosquito pushup = 1 erg = 10^{-13} JD
1 barrel of oil = 6 × 10^{9} J = 6000 JD
1 pizza (p) = 10^{7} J = 10 JD (medium, with sausage and pepperoni)
1 Pizza (P) = 10^{17} J = 10^{11} JD (one-half of the energy released
in the annihilation of a pizza and an antipizza)

From [World Factbook 1996]:
world Electricity:
capacity: 2,773,000,000 kW (ie 2.8e12)
production: 11.601 trillion kWh
consumption per capita: 1,937 kWh (1993)
US Electricity:
capacity: 695,120,000 kW (ie 0.70e12)
production: 3.1 trillion kWh
consumption per capita: 11,236 kWh (1993)
Metabolism of glucose quoted as 686 kcal/mol. Sigh. Ok...
mol is 6.022 × 10^{23} molecules, and kcal is 4184 J.
So metabolism of a glucose molecule yeilds 0.4766 × 10^{-17} J.
US per capita primary energy consuption is ~220 million Btu.
