Reply #13: True - but consider

[Rabbit of Caerbannog]

the vast amounts of cellulosic material currently going to waste, i.e. burned (here in VA developers clearcut land for developements and bulldoze up hugh piles and burn it), landfilled, not to mention all the animal waste (manure etc). Not a panacea - but part of a brader solution - as is biodiesel, wind, low-hear hydro, CONSERVATION. And don't get me going on solar - solar rocks! Efficiencies are going up, prices are going down, and manufacturers are finally wizing up and making products that go beyond traditional 2" x 4" panels bolted to rooftops (solar shingles, metal roofing, skylights, facade glazing, etc...). I've devoted my entire career in this area and finally feel I'll be vindicated before I'm dead :P
