In Houston, 0% of people have switched to a plan that has some renewable energy component to it. Another 0% have switched to a plan that is partially renewable, while 0% have switched to a plan that powers homes completely by renewable electricity. This of course means that 100% of people have remained on a plan powered by traditional sources of electricity such as coal or nuclear power.
When you look at the rates provided by a company - whether on a site like Electricity Prices, Compare Electricity Companies, Compare Electricity Rates, or the company's specific website - you should first determine if the rate you are seeing in an average rate based upon a certain number of kilowatt hours (kWh) used in a billing cycle or it's simply the rate, regardless of usage. It is important to view the Electricity Facts Label (EFL) for the plans you like so that you can learn if the plan is fixed-rate or variable-rate, what you are being charged for energy by the company, what surcharges you will be assessed by the utility company for your area, and what other fees the company might assess. If you're not careful, the cheap Texas electricity you think you found might cost you more than you realize.

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 2Best Electric 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. 
Utility companies are responsible for transmission and delivery of electricity even in energy deregulated parts of Texas and should be contacted in the event of a power outage. Your retail energy supplier may provide you competitive electric rates or exceptional customer service, but they cannot repair power lines or restore your service.
