Energy Crops- Non Edible
Im not so sure energy crops have to be non-edible. Edible energy crops can be grown especially to increase biogas yields & power yields from anaerobic digesters.

Surely energy crop is a crop grown purely for the production of energy????--Alex 14:53, 24 July 2006 (UTC)


 * There are non-food energy crops. It would be interesting add this quality to the information: this is a food energy crop and this is a non-food energy crop (i.e. Cynara cardunculus). Also algae are energy crops. --Mac (talk) 12:31, 3 June 2008 (UTC)

Comparison chart - time components
Shouldn't these units have a time component? Like "US gallons per acre per year" and so forth? Atario 08:25, 9 March 2007 (UTC)


 * Good point, they certainly should! A reader assumes that they are compared over ther same time period, but this is nowhere stated.  Also, I cannot find these figures at the cited Global Petroleum Club website; they need a proper reference accessible to all readers. DavidCooke (talk) 23:08, 21 November 2007 (UTC)

And there is no time component in the "Gas Biomass (Methane)" section where the energy yield is stated as "2 GWh/km²". Is this yield per year? Or is it per crop, in which case, how many crops per year, just one? What is the reference for this number? JDHeinzmann (talk) 03:31, 29 May 2009 (UTC)

Reworking
Presently this article is disjointed. It has far too many subheadings for such a short article, they need to be condensed. Also the huge tables that have been incorporated are interesting but the detract from the flow of the article, I think they should be moved to a separate article completely with interwikis.--Alex Marshall (talk) 08:59, 5 December 2007 (UTC)


 * I think some background information on biodiesel should be added, such as what is it primarily derived from. (Wackabow (talk) 22:19, 16 October 2017 (UTC))
 * I also thought this article was challenging in some ways. Rape should be spelled out to rapeseed because it was confusing to read. (Wackabow (talk) 22:19, 16 October 2017 (UTC))

Hemp? Hemp seed?
I know that legalization supporters have suggested hemp's ability to be used for ethanol. Do published, citeable statistics exist for energy conversion or cost effectiveness of growing hemp as biofuel? It would certainly be interesting to compare its usefulness to other crops.

Energy Crops are Inefficient
Has anyone all the numbers to support/refute the use of "energy crops" over photovoltaic (PV)conversion ? Let me contribute some.

The best land-based sunfall bioconverter known is corn (maize) at least in the U S "Corn Belt". It is some 21 times less efficient than PVs in terms of land area required, averaged over a year. Additionally, corn requires huge amounts of water and petrofertilizers, not to mention continuous agricultural labor. PVs do not.

So, what is the point of "energy crops" -- at least those grown for the single purpose of energy production : thus byproduct energy is another story altogether. —Preceding unsigned comment added by 70.157.178.230 (talk) 09:35, 7 February 2008 (UTC)
 * original research observations. However I might point out that enegy storage and transportation is a significant consideratiion you appear to be overlooking.  Beyond this there are also issues of maintenance and initial capital investment barriers when implementing PV as an alternative to biofuels.Zebulin (talk) 08:29, 15 April 2008 (UTC)

British English or American English?
Is this article in British English ("maize") or American English ("corn")? --DThomsen8 (talk) 21:06, 4 July 2009 (UTC)

Unclear - needs examples
I couldn't figure out, from a quick glance at the article, what sorts of "crops" are actually used to produce "energy". If I have several acres of forest in my backyard, and I cut down trees for firewood, is this an energy crop? What other kinds of plants are typically used to produce energy? (I heard something about corn.) --Uncle Ed (talk) 18:10, 29 January 2011 (UTC)
 * I agree with you. I was wondering what biofuels can be produced from the “green waste byproducts of food and non-food energy crops” that was stated? (Wackabow (talk) 22:17, 16 October 2017 (UTC))
