Yes, purely radiating away heat might be tough. That said, 400 years at 2% is more than a factor of 2,500 - I'd expect some quite substantial changes to go with that as far as industry and society are concerned. For example, a lot more energy use might not be waste heat but creation of stuff or waste being high energy energetic radiation.

I think current "future" tech aim for something like ~50% (theorical) efficiency, and that's with a _very_ wide temperature differential that would put a real strain on materials.
