IC2 has the most stupidly easy power generation of any mod I've ever seen. Coal, lava, solar, wind, water. If you can't find a way to make power with IC2, something is wrong.
Engineer's Toolbox can also generate IC2 power, and has it's own converter from RF. Or it did in 1.6.4. I'm not sure if it still does.
It's not making power with IC2 that is the problem. It's making it in any significant quantity. Most IC2 generators put out stupidly low amounts of EU/t, so you are forced to spam them to get the power you need. I, personally, dislike spamming generators, so I opt for solutions with higher output, which IC2 is lacking (outside the reactor or maybe the RC Turbine).
