Photovoltaics are pretty sustainable; let me explain why I think so before I get jumped! The original cells made in the fifties at Bell Labs are still generating power today; very long lifetimes exist with well built silicon infrastructure. New third generation silicon technology has the potentia

Of that I am not so sure.
there are a *LOT* of internal combustion engines
around. I mean a *LOT* of them. And they
are pretty broadly deployed
I think the problem is that driving 12,000 miles per year is not
sustainable, no matter if you use PV, biofuels, whatever

Yeah, *but*
How sustainable are PV arrays?
As much as I like PVs, and
one acre of PV will produce enough electricity to run an electric car
roughly 1.5 million miles per year... Or alternatively, you could run
it 12,000 miles or so with about 300 square feet of PV.

I thought he said 800 gallons of ethanol per acre. But I don't know if
either one can yeild that much. I'd be interested to know.
However, Michael, perhaps you need 4 acres and rotate around so you can
have everything. I know, wishful thinking.
Cheers,
John

Thanks Jason, Katie and Keith. The reason for my post had mostly to do with soil degradation. I was researching what crops gave the best yield for ethanol production and began looking at sugar beets as a possibility. However, the research suggests that root crops can't be planted every year bec

I'm glad so see discussions about WVO (supply, sustainability and big
business
Here in New Paltz, NY, we're looking into a combination of WVO and
locally grown and pressed oil. Local farmers are already planting
rapeseed (canola) as a winter cover crop and plowing it under in the
spring. They tell me it wouldn't be that hard to harvest the seeds
first. Our village
