I guess u mean ethyl alcohol.
you can burn ethyl alcohol to generate electric power, then you will get carbon dioxide and water. (complete combustion)
Here is the equation:
CH3CH2OH(l) + 3O2(g) → 2CO2(g) + 3H2O(l)

I am sorry to hear about that....I can explain it to you briefly.你只係需要直接燃燒alcohol (我指的係乙醇ethyl alcohol) , 就可以發電.點解可以直接燃燒呢?因為乙醇的沸點低,佢地的分子之間只有很弱的范德華力 (簡單黎講即係只有好弱的力) 連繫住.所以一燒佢地,就可以釋放到能量,就可以發電 (佢地係完全燃燒,所以冇任何的污染物,十分乾淨的發電方法).
