scale and learning effects have basically disappeared for solar generation, both thermal and photovultaic. there is a smaller amount of data from the d.o.e. for solar only showing declining costs for 1998 through 2008. so if we put all of those data together, the conclusion i come to is that the assumption that their industry effects yet to be had is at best far from obviously correct. then there's the level playing field argument. and the argument basically is that conventional power generation gets subsidies. and so renewables can't compete without similar treatment. that's kind of a non se-- then ought to get rid of those rather than introducing a new distortion of the market. but that aside, if you actually look at the eia data on federal subsidies per megawatt hour, these are the numbers you come up with. 63 cents for natural gas, 64 cents for coal, $52 and above for wind and $968 per megawatt hour for solar generation. we can argue about the methodology and argue about the numbers, but the differences in these magnitudes are so large it's really quite difficult to conclude that the
