A new posting had mentioned renewable Energy generated in-state in California during 2004 was 10.6%
but adding the Large Hydro(Which is also Green Energy, the figure will be 10.2% + 14.9% = 25.1%)

Just wish to clarify that in the whole, California's energy source is at least 25% from Green Power.
Wind at 1% and the small  0.3% of Solar Power hopefully will be changed by the new Solar Initiative!

 
                                              Direct Energy                             
  Source of power generation       Percent.          Texas avg.      CA. Avg.         SCE(in-state)
  Coal and lignite                        38 %               39.2%            21.3%               19.8%
  Natural gas                              46%                45.9%            40.8%              41.9%

  Found the information, it's Direct Energy in Texas, Texas Avg, CA. Avg.(http://www.energy.ca.gov/html/energysources.html)
  and (http://www.energy.ca.gov/electricity/gross_system_power.html) and SCE.

  California breakdown represents In-State power for about 80.92%
  The other 19.08% are from non-renewable power plants but mainly from Large Hydro power generation.
  12.75% from US SouthWest
  6.83%   from Pacific N.W.
