Texas is pushing homes and businesses to conserve electricity for a second day in a row to stave off blackouts as a punishing heat wave bakes the western U.S.
Temperatures will top 100 degrees Fahrenheit (38 degrees Celsius) from Montana to Southern California Tuesday, according to the National Weather Service. Dallas will reach 99. With many power plants unexpectedly down for repairs, officials warn the grid may fall short. It’s the second time since the deadly February blackouts that Texas is pleading for conservation.
