Pickle juice is similarly effective for the electrolytes. I use that on century rides.
Really, the sugary drinks aren't all that great at hydrating you. The best thing is water, plenty of it. How much energy you want to add to the drink depends on what you are doing - if it is hard, physical labor then you'll burn the sugar but you'd be better off with something like an energy bar with some protein and a LOT of water.
For times when you are working hard, sweating heavily and don't have time to stop and eat, there is a product you can get at fitness stores called 'Gu'. It is a gel and my favorite one is 'Roctane' as it has aminos and electrolytes in addition to a good carb profile for fast and sustained energy. Again, drink a bunch of water. I start using that about 2 hours into a long bike race - at that point I've already burned all of the glycogen stores in my muscles and liver and have to start replacing it. Normal activity doesn't require that, you have to be stupid enough to look at a 100 mile bike race in August in Texas and think "Yeah, that looks like a blast!".
There are other gels out there, the ones by Powerbar taste like someone drenched in cheap perfume smells (How's that for a descriptor, lol) those are too sugary - immediate jolt followed by a crash for me.
If you have time to fuel up correctly pack fruits like bananas and strawberries, some nuts and a plain old gallon jug of cool water to go to work with - obviously it'd be hard to pack that on my bike but that's what I'd prefer around mile 80. Also - do NOT overeat when it is hot and you are working hard, you will make yourself well and truly sick
Final thought: Once you are out in hot weather and worn out it is too late to really do things right - think ahead and drink plenty of fluids the night before and before you begin the work. The ounce of prevention v. pound of cure cliche is applicable here.
Wayyyyyyyy more than you asked for, sorry.
