I had this problem myself. Frankly, I strongly dislike TE all around, for the most part - it's very boring to me in the same way AE is. I actually use Railcraft for most of my item transport, so I really wanted the noisy, clanking engines on my boiler.
I found the simplest solution to this is to install the mod Mekanism. It has a battery block called an Energy Cube, you only need 1 of them. It accepts MJ as input and can output any type of power, including RF - very useful. You don't even need all of the modules of Mekanism, just Core and Engines (or something like that, forget what the machine module is called), though I also like to install the Tools module, as it causes zombies and skeletons to have gear way more often, making them much more interesting to fight.
It's much easier than the EnderIO method - just place one block, hook it up to kinesis pipes on the input and conduits on the output, connect the conduits to your cells, and done.
