At the moment power gen is being overhauled to be more modular. You get machines that convert between different forms of energy, e.g. kinetic (rotation) -> EU, and then a windmill that generates this kinetic energy. Similar with nuclear reactors: they don't generate EU directly anymore, but heat up coolant. This heat is then extracted by a heat exchanger, and can be converted to EU in several different ways that differ in EU yield and complexity. In the end, you get about twice the yield of the old direct-to-EU reactor. So in general EU generation gets more realistic, but more steps are involved in setting up power gen, and you have more options.
So, contrary to those who claim there is nothing new in experimental, a lot of changes are being made incrementally. It's kinda sad that the first changes were not really on the exciting side, which drove people away.
