You betcha! Most Texas electricity suppliers offer plans that include a percentage of energy sourced from renewable resources, such as hydro power, wind power and solar power. Some are totally sourced that way. These plans are a great way for Texas energy customers to help the environment without breaking the bank. In addition to green energy plans, many Texas suppliers give customers the option to purchase renewable energy certificates, or RECs, that further offset customers’ carbon emissions. The purchase of RECs also helps fund research and usage of renewable energy sources, so that Texas can stay at the forefront of eco-friendly power technology.
One desired effect of the competition is lower electricity rates. In the first few years after the deregulation in 2002, the residential rate for electricity increased seven times, with the price to beat at around 15 cents per kilowatt hour (as of July 26, 2006, www.powertochoose.org) in 2006. However, while prices to customers increased 43% from 2002 to 2004, the costs of inputs rose faster, by 63%, showing that not all increases have been borne by consumers. (See Competition and entry of new firms above for discussion on the relationship between retail prices, inputs, and investment.)
Compared to the rest of the nation, data from the U.S. Energy Information Administration which publishes annual state electric prices  shows that Texas' electric prices did rise above the national average immediately after deregulation from 2003 to 2009, but, from 2010 to 2015 have moved significantly below the national average price per kWh, with a total cost of $0.0863 per kWh in Texas in 2015 vs. $0.1042 nationally, or 17 percent lower in Texas. Between 2002-2014 the total cost to Texas consumers is estimated to be $24B, an average of $5,100 per household, more than comparable markets under state regulation.
