Density.

But what really matters is conversion of solar energy into stored 
chemical energy (cellulose).  And some other things like drying energy.

Also groves of monoculture willow is probably not a good idea.  There is 
at least a chance that firewood is coming from a healthy sustainable 
forest ecosystem.

Thank You Kindly,
