Remember the Alamo

If the Lone Star State gets any more giving with its free power for electric-vehicle drivers, all your exes may live in Texas, too. Dallas-based TXU Energy is starting a new plan to use some of its excess wind energy by promoting a "Free Nights" program. As you might suspect, it lets EV-driving customers charge for free between the hours of 10 pm and 6 am, according to Plug In Cars.

The promotion makes sense because those howling Texas winds are especially strong at night. Since TXU gets much of its electricity via wind power, there is excess supply after dark. This is a good thing for EV drivers, because about 80 percent of EV charging is done at home. And if you want to emit the least amount of CO2 possible, then it's an even better combination. Of course, the program may also result in higher rates during daytime hours, but, hey, nothing's free, right?

Meantime, Texas is about on par with the rest of the country when it comes to publicly accessible EV-charging stations. The Lone Star State, which accounts for about one in 13 US vehicles, also accounts for about one in 13 public charging stations in the country, according to US Department of Energy figures.
