Texans don't trust the power grid

• And 51% of the poll's respondents said they thought it's likely there will be a widespread failure of the electric grid this summer.

Threat level: Grid operators said last week that there's a 12% chance of rolling blackouts in August because of increased demand.

Flashback: Last summer, Texas set 10 new all-time peak demand records and Texans were asked to conserve electricity at least 11 times.

The fine print: The poll has a margin of error of +/- 2.83% and was conducted May 31 to June 9, before ERCOT warned of summer outages.
