yep, sugars have more internal energy than peroxide (you can just add up all the bond enthalpies for a quick estimate). Peroxide is used in fuels because 1.) it is much easier to activate than sugars because it is thermodynamically metastable and 2.) it is an oxidizer. Oxidizers help accelerate the release of internal energy from energy-dense fuels (e.g. kerosene...or even sugar). Another way to look at this is reduced vs oxidized. O2 is the most (stable) oxidized form of oxygen while H2O is a reduced form of oxygen. H2O2 is intermediate. Hexane is a very reduced C6 compound (high internal energy) whereas 6 CO2 molecules are the most oxidized (low internal energy). glucose is intermediate between hexane and 6 CO2 molecules but closer to hexane in terms of how reduced it is. Glucose is quite energy dense and it is for this reason that it is used by plants to store energy from sunlight.
