Yep falcon, the more fuel that comes from chemical farming, the more biomass is burned.  Biomass should be recycled back into the soil to provide maximum carbon sink activity.  That happens with conservation land, wetlands, and forests and even with farms, organic farms that is.

Fuel farming results in more GHG in the atmosphere, mainly because it takes carbon stored in the soil and releases it.  And it releases GHG that would normally be removed from the atmosphere.

When corn is grown organically, compost that stores carbon is added to the soil.  Everything but the corn kernels are put back, the styalks, roots, leaves, maybe even most of the carbon locked up in the corn kernels are returned if the manure from the animals it is fed to is composted too.

The balance depends upon returning the same amount of carbon to the soil as was extracted.  Productive living soil, like that under natural prairie grass, extracts 1.8 tons of CO2 per acre per year from the atmosphere and stores it underground.  The prairie soil was 20 feet thick when farmers first plowed it, now it is an inert chemical layer that blows in the wind, wherever chemical farming has ruled.

All that millenia of soil storing cO2 was burned off by chemical farming, chemical burning.  And now each year the amount it used to store stays in the atmosphere.  The dynamic balance is the thing here.

The self and mass deluding idea that because corn stores CO2 then it is released as ethanol fuel burned in cars, but is reabsorbed again and again, over and over.  Similar to the cycle of rain and evaporation in the water cycle.  The idea that constitutes zero emmision fuel is erroneous.

The land used, not to mention the fossil fuel for tractors and chemicals, results in more and more cO2 in the atmosphere every year.  At least 1.8 tons per acre per year from prairie land converted to chemical fuel farming.

Now compare this process of fuel farming and gas guzzling..  to..

Charging up plugin hybrids with solar power harvested from already used land, rooftops of buildings all over the country.

It leaves the land that is removing cO2 from the atmosphere alone.  It is only mounted on roofs.  And it supplies enough kwh to replace 90% of present liquid fuel use, through the plugin hybrid's 40 mile battery range.

Renewable electricity charging plugin hybrids is technology ready to mass produce now.  Diverting any capital away from that solution dilutes it and slows the eventual cut in fuel consumption and GHG release.

Plugin hybrids have the same utility as gas guzzlers and can be fueled at regular gas stations.  The additional investment by auto companies to add plugin power to existing vehicle lines is minimal.  An electric rear axle added to a regular front wheel drive car, plus batteries is it.

Better to apply capital to this, than ethanol, Vinod.
