host: what do you think, deborah gordon?guest: i think the call ther -- caller is exactly right, it's all about the price of oil. when only is $35 a barrel, very little economicically competitive against it. that's where we were for a very long time. i think if the price of oil were higher, we could use a whole range of alternatives, definitely using solar. host: what are your thoughts on solar? that's another area where critics say you're picking a winner, solar and wind, tax subiedies with very little result. guest: oil has wind and tax subsidies. we picked that for a century. and megainvested in oil so it would be great to think we could be so honest to strip away and make the level playing field. but there are investments that you have to somehow keep supporting. but i think, again, the price of oil. have everything to do with the alternatives. i think that people will get much more innovative in themselves as many did in 2008. we had a whole different range of options it wasn't an easy time, but it was a creative time.
