I just did a comparison of odd ways to generate IC2 energy, and came upon something interesting. One turbine costs 248 steel. The amount of boiler required for one steam turbine is 18 m^3 of HP tank, or 43 steel. One turbine rotor produces 100eu/t for 41 hrs, with a cost of 99 steel. (Can someone check these numbers please?) That means that up-front, a steam turbine costs 390 steel for 100eu/t, or 0.26 eu/t/iron. A wind generator in a Mystcraft age with consistent weather can produce 2.49eu/t avg without risk of breakage, and costs 12 iron, or 0.21 eu/t/iron. The turnover point is at the first turbine replacement at 41 hours. Although a steam turbine produces more eu/t per iron upfront, a steam turbine continues to burn iron whereas the wind generators just sit there producing energy. Also, a turbine uses fuel, whereas wind generators are fire-and-forget. As such, why bother to use a steam turbine? If you're going for quick energy, use a geothermal generator or ten. If you're looking for the long haul, use wind generators. Are there any good uses for Railcraft Steam Turbines currently?
