Feb. 8, 2013 - Last Christmas, about midafternoon, high winds that brought yet another cold front through Texas contributed to a new wind power record, at one point providing about 26 percent of the electricity on the state’s grid.
The power registered from the turbines just after 3 p.m. on Dec. 25 was 8,638 megawatts, or enough to power just over 4.3 million homes.

Most Texas homes are warmed by natural gas, and the sun would have been high enough in the sky that televisions and other appliances — not lights — might have consumed the most electricity. In August, by contrast, when electricity use is high due to amped-up air conditioning and when breezes for driving wind turbines are light, wind provided 5 percent of the power on the electric grid. read more>>>
