For your trip:
(Assuming one liter in the morning and one liter at night)
1) Esbit is perhaps the lightest, no real stove, about 2oz of fuel per day for 40F water to boiling at 3000' feet. It is also the most difficult to use with slow cooking, residue and "fishy" smell. If you take them out of the packaging and put them in a baggie, they will degrade. IE, the cubes will crumble.
2) Canisters and alcohol break even due to the weight of the canister. I would need about 3oz of fuel per day for two liters. Canisters are 100g(3.57oz,) can weight is about 3.7oz, roughly can weight is about 50% of fuel weight. Alcohol is about 11000BTU/lb, butane is about 21000BTU/lb. Cutting the butane weight in half for the can gives us about 10500BTU/lb. Butane is more efficient at turning off, down and lighting, soo this is not quite a true picture. It is probably closer to 11,500BTU/lb. Anyway, there is very little difference between them.) All the weight savings of one or the other is the weight of the stove and windscreen.
3) WG, Kero, etc have about 20,500BTU/lb. This sounds *great* untill you need to pump, prime and turn off a stove. This will easily waste about 1000BTU/lb.
ALL fuels need packaging. For canisters, they are metal cans. Esbit is plastic/foil. Alcohol and WG,kero can be can be carried in a soda/water bottle. I use a second cap with a short length of vinal hose (stripped from 12ga wire) to fill and vacuume up excess fuel. Do NOT use them for auto-fuel...it has additives that will make the plastic brittle. They weigh about 1.5oz (including the extra cap) and hold 12, 16 or 20floz. Density of alcohol and WG is about .8 so a 12oz bottle, full, weighs about 10.5oz. WG is the most efficient fuel to carry. But, the stove weighs a lot...
Anyway, for general usability, Alcohol is always about the same as Canister fuel. (I never use Esbit, I tried it several times, but it always made a mess of my pot. I have a heat exchanger moulded into the bottom of the aluminum pot.) I use Alcohol for 1-4 days out. Anyway, for 10 days out, it weighs about 36oz, counting the fuel, container, stove and wind screen.
Canisters use about 1oz per day for 10 days, about the same as WG. So I would need three, 100g canisters plus a ~7oz stove(remote canister,) or, about 29oz, counting the wind screen. (Note: I have lost a couple canisters due to leaking. I usually carry a spare.) I do not like "topers" since you can have trouble with a wind screen if you don't always heat water on very low. Cans are bulkey, though. Volume is another parameter that is important to me.
For a week or longer (7-10 days out) I use WG and a SVEA. Yup, the stove is heavy. But, overall the stove and 10.5oz fuel bottle last about 10-12 days. If I cook, closer to 10 days. Just boiling water, closer to 12 days. I almost always go out for one or two weeks at a time, so it is a no brainer for me. 17.5oz for the stove, 10.5oz for the fuel and bottle. I can get about .3ox per liter, but cooking a stew means closer to .5oz/liter or about 1oz per day. You *need* a stove that will run on low! I mean very low. No pumped stove I know of will do this except the old Coleman PEAK burner at around 21oz. But this was heavier than the SVEA. Simmerlite, Whisperlight, etc. are all external stoves, IE, have a seperate fuel bottle.
Total weight for 2Liters per day is about 30oz, fuel, container, stove and wind screen.
Note that for about a 10-12 day trip, they all come close. Alcohol wins at the final weight, about 6oz. Canisters are next with about 19.5oz. WG is next with 20.5oz. I do not worry about final weights. My starting pack weight, with all the food, is so heavy, I reduce my starting weight (and volume) as the more important number.
From all this, you can assume that you might just get away with 2 canisters making them the lightest to start with. As I said, I have had some trouble with leaking, though.
