For example, in the supplementary materials to Tilman's Science article Carbon-Negative Biofuels from Low-Input High-Diversity Grassland Biomass: http://www.sciencemag.org/cgi/content/abstract/314/5805/1598 Table S3 shows that the best GHG-reduction comes from producing electricity from the biomass (10,088), instead of ethanol (6,164) or synfuel (9,626). (Numbers are kg CO2e / ha) To emphasize the point made above “the energy carrier of the future is electricity” consider that even biomass might be better used to produce electricity than liquid fuel.

Yes, if sequestation works, then biomass gasification or coal-biomass gasification with CCS gives you negative carbon electicity. Interesting.

Is decarbonization all but inevitable. I think there is a difference between greens and climates about priorities and directions.

Wait... we have roofs. We don't need 10,000 new square miles. They are already there, in spades. Best, D What we forget to think about with solar is that…

wait…

Wait…

we have roofs.

Best,

Measures must be taken as soon as possible to keep control on global population to avoid the increase of the the contamination on the atmophere, oceans and rivers.
