Bees are definitely a lot easier to manage if you already have the infrastructure set up to run your base.
If you're up for it, there are a lot of methods for producing energy from bees. The most common method is to get a few bees from the oily branch and then using the oil they produce to power steam boilers or generators. Bees from the infernal branch can also be used as they produce phosphor which can be processed into lava.
The youtuber GenerikB is setting up an interesting system where he uses thaumic bees to produce vis which gets turned into EU by a magic energy absorber (although this is pretty late game) and then using more bees to clean up the flux produced.
Youtube can be a very good resource for information and tips for bees. GenerikB has a "
BEEcademy" series in which he shows some of the basics for bees. Florastar also has a
Bee University series (which was actually GenerikB's inspiration. She even has a bee item in the game named after her!
Altitude isn't a factor but most bees need to have their apiary/alveary exposed to direct sunlight, meaning there are no blocks above it. Bees with the cave dweller trait do not need sunlight and with the late game genetic machines, any bee can get that trait.
To be honest, when you're just starting out with bees, a few apiaries out in a field is really all you need.
One resource you will need is seed oil. To start off with, bonemealing flax plants and then breaking both portions of the plant will probably give you the most oil. This can be easily automated with block breakers and deployers. This would be fairly easy if you had some sort of skeleton grinder. A sulfur torch farm for sulfur goo is also a very viable option as it has zero running cost and depending on the number of sulfur torches you use, it can be pretty fast (sulfur goo works like bonemeal). If you're into tree breeding, breeding up to walnut/chestnut and then occasionally harvesting a few trees will give you more seed oil then you know what to do with.
A resource worth checking out if you want spoilers is
this bee wiki. It's the best one I've seen.
