A study conducted by a government laboratory in partnership with General Motors revealed that the U.S. has the land, water and transportation resources necessary to make a whole lot of cellulosic ethanol. Enough, in fact, to replace one-third of our gasoline needs by 2030.
The seven-month study evaluated the country's ability to complete each step needed to produce biofuels from "seed to station" and at what volume. Researchers found that the U.S. could produce 90 billion gallons of biofuel per year by 2030 and that it would cost about the same as producing the equivalent amount of gasoline. The laboratory assumed the fuel would be made of "energy crops," fast-growing plants that would not use the same land as that used for food crops.
Other assumptions were that each ton of biomass would create 95 gallons of fuel and that each ton would cost $40. This would make the biofuel competitive with oil prices when oil is priced between $70 and $120 a barrel. The savings in CO2 emissions were calculated to be 250 million tons per 60 billion gallons of cellulosic ethanol.
The big details missing from this study are how the fuel would be made and what exactly would be used to make it. There have been a lot of successful trial runs of biofuels and biofuel-blends, but no company has reached a point where they could manufacture cellulosic ethanol at a commercial level.

We all know that plants are inefficient solar collectors, and we'll then consume energy to convert the plants into oil and into fuel, and then we'll waste energy converting that chemical energy into mechanical energy at the engine by burning, etc.
Please, can't we move forward instead of sideways like a crab????

Doesn't sound all that different to me. Hydrocarbons are a bad plan. Hydrogen, which burns with a byproduct of water, seems better. You can even use bio-solar to produce it!
Oil bad. Agreed. But seriously, this is only a step sideways.

The point of cellulosic Ethanol is avoid burning food. It's more like burning hay, or something like that. Not entirely unrelated, but it's not quite the same thing.

There are energy crops that grow on land that will not support food crops, arid land, marshy land etc, etc...Even using corn is sensible. Only 1% of all the corn in this country is used as food for humans. 80% is used as animal feed. 20% of that goes overseas as animal feed. If we make ethatnol from that 80% we not only get a superior fuel we get much higher quality animal feed and eliminate the need for pertoleum fertilizers, herbicides and pesticides.
I we just collect the seed pods from Mesquite trees that grow wild we could procuce 30 BILLION gallons of ethanol a year with no planting, irrigating or fertilizing.
I we use cattails to further clean the discharge water from waste water treatment facilities we could replace all the 200 million plus gallons of daily gasoline used in this country with ethanol made from the startch of the cattail. Even that route would use a whopping 1.46% off all the agricultural land in this country.

However there are some applications such as flying airplanes which are not likely to work well on batteries or fuel cells etc (at least not in the medium term) and for these cellulosic ethanol is probably the best current solution. Note also that we do throw away a lot of bio-waste which could be used for this rather than just being allowed to rot (and produce CO2)
