In theory, potatoes, onions and the like are supposed to be kept in cool, dark places, which helps keep them from sprouting. However, in my house, things stored in the available cool, dark places tend to be forgotten about, resulting in unpleasant surprises.
So now I keep my spuds and onions in a three-tiered wire hanging basket out in the kitchen, where I'm more likely to see them and remember they're there to be used. If they sprout, I use those first. And if they go off before they can be used, they're more likely to shrivel into harmless, dessicated mustiness than to dissolve into pools of fetid matter.
My kitchen is (unfortunately) not very bright, so the potatoes usually don't develop green areas from exposure to direct light, and if they do, I just cut that part off. And keeping the onions and potatoes in separate tiers in the open-air basket seems to be far enough apart.
A trick I used to use was to keep them in the fridge. They keep a lot longer that way. The starch in pototoes turns to sugar when they're kept cold, making odd-tasting potatoes, but it goes back to normal if you leave them at room temperature for a day or two. I stopped doing it because I'd forget to take them out ahead of time. They also use up too much space, and the onions tend to perfume other things near them. (I still do put more perishable sweet onions in the fridge.)
Once bananas reach the stage of ripeness I prefer I stick them in the fridge, too. The skins turn black, but the fruit inside is fine.
