Plants need more than just CO2. CO2 fertilization works well in greenhouses, where there's a surfeit of everything else. In practice, CO2 might stimulate growth in some places, but not in others. A bigger stimulant to growth is expected from a longer growing season: a longer period above the temperature at which plants are dormant. The economics are already in favour of Photvoltaics in San Diego. Partly, that's a result of a subsidy which I know you abhor. Even without a subsidy, it would be economic to do so here if electricity prices were not to decline in future. (I think this is true. I learnt this sometime ago and perhaps electricity prices have already fallen sufficiently to make a liar of me.) This is what I was saying to you some time ago: it is in the interest of oil producers for the price of oil to fluctuate. The occasional periods of low prices scares off investment in competition or substitution. Alternatively, the occasionally high prices might scare off development of oil-intensive technologies. The trouble with the latter argument is that I can't think of an oil-intensive technology that isn't well developped. Ashley
