Why is ethanol produced from corn not necessarily a sustainable option as a source of energy? Explain.Biofuels:Biofuels are types of fuels that are produced from biomass instead of from geological processes such as oil. Biofuels are considered a renewable source of energy...

Producing ethanol and biodiesel from corn and other crops is not worth the energyPatzek, Tad WPimentel D,Patzek T W.Producing ethanol and biodiesel from corn and other crops is not worth the energy. NRR . 2005
They can be simple, like monosaccharides. They can be more complex, like disaccharides or polysaccharides. Hydrocarbons have a key role as a source of energy in living organisms.Answer and Explanation: Starch is a polysaccharide made of numerous glucose units joined by glycosidic bonds. It ...
The problem is that the amount of energy we get from corn-based ethanol isn't much more than the amount of energy that gets put into making it,so it's not really worth it. Tina? FEMALE STUDENT: But ethanol made from cellulose is different?
laboratory found that it takes approximately three BTUs of energy to produce four BTUs of corn ethanol. Gasoline, on the other hand, takes five BTUs of energy to produce the same four BTUs. Although the net energy from ethanol production is greater than that of gasoline, gasoline is still...
The problem is that the amount of energy we get from corn-based ethanol isn't much more than the amount of energy that gets put into making it. So it's not really worth it. Tina? Student: But ethanol made from cellulose is different? Professor: Yes. It's possible to get a vastly ...
corn ethanol seems like a great idea.One might get a bit more energy out of the ethanol than that used t make it,which could still make ethanol more sustainable than gas generally,but that's not the end of the problem.Using corn to make ethanol means less corn is left ...
One might get a bit more energy out of the ethand than that used to make it, which could still make ethanol more sustainable than gas generally, but that’s not the end of the problem.Using corn to make ethanol means less corn is left to feed animals and people, which drives up the...
