My two cents:
Desert, especially if you can find one of those desert temples as the initial start.
In the Desert, you've got Oil spawns, lots of Cactus, and the Austere line of bees. I happen to like the Austere line because they are Nocturnal, meaning they will operate even at night. Since it doesn't actually rain in the Desert, 'strong flyer' is implied as well, if not explicitly stated. This means they will produce combs 24/7 with no stoppages in supply, and as a result they actually end up producing more combs than you might otherwise think from their stats. Of course, breeding them with more productivity would be an enjoyable pastime.
Solar panels would also be slightly more efficient, due to lack of rain, and IC2 wind generators would be more stable because you won't have to accommodate for the sudden influx of power which storms provide which can break them if not properly prepared. Also, if you are running with Thaumcraft3 installed, cinderpearl flowers are an excellent source of blaze powder without needing access to the Nether.
And hey, you'd even have a theme song...
"I been through the desert on a pig with no name, it felt good to get out of the rain..."
If you find one with Red Hills nearby, that would be even better, as Red Cobblestone can be turned into Clay.
