The problem with e85 is that most current vehicles are not designed to run on it. Nearly every vehicle on the road could make use of e15. Conversion to e85 is not difficult but typical consumers will not take such steps.
There are large well funded corporations out there that will do almost anything to keep the ice from dying.
Add ten or fifteen years to each of the estimates and you might be more realistic. Hydrogen is only an energy medium. A chemically better way to store electricity than batteries. But it will only work when we get the fuel cells right. Eventually all electricity needs to go carbon less. Mostly that means nuclear.
When it is time to replace the vehicle though these will be a wise choice.
Imaginative suggestions like this are proposed here all the time. The hard part is changing current real world behaviors.
If one makes the conjecture that we are rolling the dice the implied assumption is that as a whole we as humans, in this closed system of a planet, do actually have some effect on what happens. Is it really reasonable to expect that we can have such a huge effect on the planet? Are our egos that big that we feel that we can somehow alter that which was set in motion by massive forces outside of our control? I for one don't buy it. We are not yet that capable. At this point we are still subject to the whims of the universe. If the planet gets hotter we will adapt. If it gets colder we will adapt. However we will have no net effect on those changes.
Harvey D you are correct with the exception of Brazil. They are energy independent now and 25% of their liquid fuel is currently ethanol. That percentage will only go up as worldwide demand for oil increases. Ethanol is not the only solution but it will have its place in the future of the worldwide fuel mix.
$33,500 (After tax credits) Not outrageous for what you are getting. This is an entirely new package of technology and GM is not going to make money for the first couple of years. I agree that 34k is not affordable for everybody but they could justify charging a lot more. And lets face it, first adopters are willing to pay a premium.
Yet the EPA refuses to rule on the E15 Waiver requested by the ethanol industry. Even if we wanted to (and some of us do and some of us don't) we can't buy ethanol in any concentrations other than e10 and e85. I personally would love to clean out the old fuel injectors in my 94 honda with E15. Loan guarantees won't fix that.
Bring on the H2 and the Ethanol and the M85 and NGV cars and more nuclear power and algae bio-diesel and EVs hooked to backyard windmills. We need all of it so we can stop sending our cash to other countries for their oil.
Don't forget that 10% of your 15% calculation is Corn Ethanol. Personally I think we could do with a lot more of it but not everyone shares my opinion.
$1.00 per gallon is terrific. To bad we will never be able to buy it because the EPA will not allow more than 10% of our nations gasoline supply to be ethanol. So much for environmental protection.
There gonna make those cars anyway. I'll give them some credit for trying.
The EPA has refused to rule on the ethanol blend wall. Currently the EPA limits all fuel sold (exception of e85) to have a maximum of 10% ethanol. We are about 10% now with only corn ethanol. Nobody in their right mind will invest in cellulosic ethanol if there is no market to sell it. We need E15 and E30 to be approved by the EPA. Otherwise 2nd gen bio fuels are dead. Gotta love how the Gvmt demands that we make it and then tells us that we are not allowed to use it.
"Compared to other available solutions, a typical ethanol plant can gain $1 million or more per year using the enzyme, according to the company. " This is good news. Incremental gains in ethanol production will benefit everyone.
Until we are able to handle 15% we can't move to 20%, 50% or 85%. Anything above where we are now keeps oil dollars out of the middle east. SJC is right, this is not an all or nothing proposition.
If the US fleet averaged 50 mpg we could run half this country on ethanol.
The idea is to improve yeilds on existing cropland so that production of ethanol can be increased without additional deforestation. The demand for fuel will continue to rise (in the absence of a Global CO2 tax) and that fuel will be provided. Better to do it on existing land with higher yeilds that to expand onto new land with current yeilds.
Thats just silly!
Seems to be going in the right direction at the moment.
Did I miss something? It does not appear that Toyota is releasing these to the general public yet. :(
Patience ... there is no need to jump to conclusions. We should know much more about this trend in a few hundred years.
