"a significant portion of electricity in Texas is generated by wind,"
anybody know the percentage?
Looks like there is some for SA, but significant portion?

For the past two years, Texas has been the top wind producer in the United States. As of April 2007, Texas had an installed wind generating capacity of 2,768 megawatts (MW) with more than 1,000 MW of new wind capacity under construction. According to the American Wind Energy Association (AWEA), U.S. wind power generating capacity increased by 27% in 2006 and is expected to increase an additional 26% (more than 3,000 MW) in 2007 due to strong demand, investment of private capital, and the support of federal and state governments. AWEA predicts that two-thirds of that growth will occur in Texas, as three of the five largest wind farms in the nation are located in Texas.

As for Texas, the total net 2002 summer, electric generating capacity (all sectors) was about 94,488 MW, of which fossil fuel, generation was 93 percent, nuclear 5 percent, hydroelectric about 0.7 percent, and non-hydro renewables about 1.3 percent.
So it's probably fairly safe to say that wind generation in 2007 is around 2.5% of total energy production with another 1% under construction.
Also of interest from the second article:
Texas ranks first in the nation for its total renewable energy potential, which stems from its diverse climate and vast size. In addition, each of the state's renewable resources, such as solar, wind, and biomass potential, rank among the top in the nation. The wind energy potential of Texas is about 136,000 MW, a very close second to top-ranked North Dakota. This is almost twice the state's electricity speak demand. By the end of 2003, U.S. ulative wind energy capacity was 6,374 MW, with Texas, at 1,293 MW, ranking second for the most ulative wind power capacity in the nation.
Similarly, Texas lists among the states with the greatest solar potential. South and West Texas and the Panhandle provide the best settings for large-scale wind and solar projects, and the best biomass resources are located in East Texas and the Panhandle. By developing these extensive handle renewable sources of energy in the future, Texas could not only provide for its own energy needs, but also become one of the largest exporters of renewable energy.
By more than doubling wind capacity since 2003, Texas has overtaken California for the lead in wind energy production.
