Species Density Heat Value
lb/cu. ft. lb/cord BTU/lb Million BTUs/ton Million
BTUs/cord
Willow 23.7 3,034 8,400 16.8
25.2
>snip>
* all values are based on oven dry weight
One Full Cord = 128 cubic feet
Willow Yields 5-8 tons / acre, non-irrigated
Coal yields 20,974,000 BTUs / short ton
One acre = 208.71' x 208.71'
Using the same conversion rate for willow as exists for coal, 10,452 Btu's /
KwH, one mean acre of willow yields 10,447 KwH's.
One acre, 209' x 209', is sufficient to supply ~1.19 homes consuming 1Kw
each hour for an entire year.

Darn, that's a chipper thought and reasonable.

Do you have a pointer (http://) available ??
Although yours and others explanations will do just fine.
