Cleaner burning, yes. More power, not a chance. Alcohol only contains
60 of the energy of gas. In Indy they get more power by burning more.
A lot more and under more pressure.

And also because an engine runs more efficiently on ethanol if designed properly
to use it.

Ethanol may only have 60% of the thermal energy of gasoline but but the extra
efficiency makes up for about half of that difference.
