I meant to flag up this article in the FT a while ago when it first appeared in the orange newspaper. It's well worth a read. A few choice points the article - or people quoted in it - mentions;

1) Grid parity will be reached first in Italy by 2011 or 2012 - (for that I'm afraid Italy can thank it's own bureaucratic incompetence in failing to license the building of adequate power supplies!)
2) Germany has 55% of the global solar market, Japan 17% and the USA, just 5% (which makes you think of the growth potential of the United States)
3) the current price of $3.80 per watt of solar capacity equates to a power price of about $0.245 per kilowatt hour - about double the European average wholesale electricity price (which I would suggest will probably go up a bit faster than solar will come down)

I keep thinking though about Texas and how wind power there has actually started to become a deflationary force, lowering the price of electricity to consumers,  as it has become cheaper to produce than gas-fired electricity since 2006. Better than wind parity in other words with gas, or as www.google.org would put it RE<G.

As this article in Renewable Energy World makes clear;

Bringing new wind energy online is critical to protecting Texas consumers from increases in the price of fossil fuels, wind energy advocates point out. Texas currently depends on natural gas to generate 49% of its electricity, and natural gas plants make up 71% of the state's generating capacity. From 1998 to 2006 natural gas prices in the state tripled, which caused the price of electricity for the average residential consumer to increase from US 7.6 cents per kWh to US 12.9 cents per kWh.
