Texas grid operator ERCOT projects it could approach that peak again on Tuesday. Despite the Texas Republican rhetoric that wind and solar are unreliable, Texas has a massive and growing fleet of renewables. Zero-carbon electricity sources (wind, solar, and nuclear) powered about 38% of the state's power in 2021 , rivaling natural gas at 42%. Experts said the Texas grid was built to withstand extreme heat moreso than the extreme cold brought by the deadly 2021 winter storm. Wind and solar have natural variability as well; solar can't generate energy during nighttime, and wind turbines don't turn when the wind isn't blowing.
