Renewable Energy Generation

  • Renewable generation by the two primary Central Texas providers – Austin Energy and LCRA – has reached a plateau. Austin Energy is considering a plan to greatly expand its renewable investments.
  • The spike in TXU’s renewable energy generation comes from large-scale investments in wind power.
  • CTSIP was unable to obtain proprietary data from LCRA and TXU for this report, but is working to include this data in future publications.

GreenChoice Subscribers

  • Austin Energy has led the nation in annual kilowatt sales of green energy for the past nine years.
  • Several batches of subscribers expired in March 2011, as well as the supply of renewable energy for the Customer Assistance Program.
  • While commercial clients make up a small fraction of the total Green-Choice subscribers, they represent 90% of the program’s kWh sales.

Fuel Mix by Major Provider

  • While conventional fossil fuel types such as coal and natural gas dominate the Central Texas provider mix, investments in renewable sources are steadily growing.
  • Austin Energy has a goal to increase its share of renewable sources to meet energy demands to 35% by 2020, in accordance with the City of Austin’s Climate Protection Plan.
  • Texas leads the nation in wind power capacity and generation with 10,223 MW of capacity, more than three times the national average. Yet distributing this power to Texas’ urban regions remains a challenge.
  • Note: Missing data reflects proprietary information from LCRA and TXU that was unable to be gathered for this report. CTSIP is working to obtain the data for future publications.

Fule Mix by Major Provider


While still a relatively small share of total generation, renewable sources, as well as conservation, have gained increasing attention across the region and in all economic sectors.


Non-renewable energy use in Central Texas is minimized in order to reduce pollution and consumers’ energy costs.


Energy, even more so than water, is a dominant theme within sustainability. Energy production consumes a great deal of water and generates air pollutants, green-house gases and hazardous waste.

Energy conservation needs to become a more prominent focus.


Indoor Air Quality


Data gathered from interviews with energy providers on reported energy generation from 1997 to most current year available. No distinction is made between residential and commercial or industrial consumers. For the 2012 report, CTSIP was unable to obtain proprietary data from LCRA and TXU, but is working to include this data in future publications.
