" I believe the reason ethanol has not been made on a commercial scale from sugar beets instead of corn is because it is too expensive".
If I remember correctly sugar beets need a lot of nitrogen fertilizer to grow them properly. So they are not cheap to grow.

Technicaqlly, ethanol can be made from any plant that produces sugars or starches. Cellulosic ethanol technology would increase the potential crop sources. I believe the reason ethanol has not been made on a commercial scale from sugar beets instead of corn is because it is too expensive.
If they have found a way to make ethanol from sugar beets cheap enough without government subsides, great.

Sweet Sorghum is another ethanol producting crop.

Green energy plan would turn sugar beets into biofuels
The vacant Spreckels sugar beet factory in Mendota may receive a green energy overhaul, as a group of former sugar beet farmers pursues a plan to transform the site into an advanced biorefinery using several high-tech processes to convert sugar beets into ethanol and other forms of energy.The energy beet refinery facility would incorporate: n Advanced ethanol production:
About 150 truckloads of harvested beets a day would be processed into advanced, second-level ethanol. During the process, some cellulosic ethanol would also be produced. Beets produce about 1,200 gallons per acre of ethanol, compared to 450 to 500 gallons per acre of corn. On an annual basis, 1.4 million tons of beets would be needed, which represents the production from about 35,000 acres.
n Biomass gasifier: Biomass prunings would go into the biomass gasifier and into a steam turbine, which would make both steam and electricity. The processed steam would be recycled for ethanol production and the electricity would be used internally. The process would produce almost 40 percent of its own electricity.n Water treatment facility: Wastewater from the beets and from the city of Mendota would be processed through the water treatment facility and converted into processed water. About 400 acre-feet of surplus water for agriculture and landscaping would be produced each year.It will be interesting to see where this plan goes.
Bring it on!

Fodder Beets may be an even better choice.

Another great crop to use is sweet sorghum. It can be grown wherever corn can grow -including northern areas- needs half the water and a fraction of the fertilizer. -Matt

I always wondered why they don't use beets for ethanol, since they use beets to make sugar.

Most people do not realize that most of the sugar produced in the United States already comes from sugar beets grown in northern states, not sugar cane (which can not be grown in most states).

ProfDude: Yes, there are plenty of crop options. However you have to remember there is also a "catch 22". You have to have sufficient quantities to produce the end product, and you also have to have a market for the end product, or the product will fail.
Folks like to claim that sugar cane is the real crop for ethanol, but when you do a little research you find that you cannot grow sugar cane in quantity anywhere. Oh, we can grow it in the southern tier states and Hawaii, but that is about it. However, sweet sorghum can be grown in most of the lower 48 states, and it has a shorter growing season. In the southern regions two crops can be grown in one year. Some strains can yield over 1000 gallons of ethanol per acre. Sounds promising doesn't it. However, we must remember, there is no infrastructure in place for sorghum ethanol. Once you harvest sorghum you must crush the stalk to extract the juice in a short period of time. If you do not, then you will lose the sugar content. With corn you can store it for months, even years. Not the case with sorghum and sugar cane.
Inspite of these limitations, I do believe that it should be researched and developed. We should never place our eggs in one basket. A diversified approach is the best solution.

I have often thought that it would be good to try something other than corn for this purpose.
I had presumed that such an alternative crop would need to be grown farther south. Apparently there are more fuel crop options available to us yet.
