No, Texas Didn't Achieve 'Record Low-Carbon' Electricity — But It Did Hit Real Renewable Milestones
“Texas achieved record low-carbon electricity production”
The argument in brief
The claim that Texas achieved record low-carbon electricity production mixes up two very different things: record-breaking moments of renewable output and the overall carbon profile of the grid. While Texas set genuine records for wind and solar generation in 2023 and 2024, natural gas still supplies roughly 47% of the state's electricity annually, and Texas remains one of the largest absolute CO2 emitters from electricity in the country.

Why it spread
This one spread because it had something for everyone. Clean energy advocates were rightly excited about genuine renewable records and wanted to share good news. Supporters of Texas's deregulated energy market saw it as proof the model works. Both groups had reasons to amplify the headline without digging into the difference between a record renewable moment and a record low-carbon grid. Good news with a simple story travels fast, even when the full picture is more complicated.
The claim is partially true and partially misleading. Texas has hit real, impressive milestones in renewable energy — but calling its grid 'record low-carbon' overstates what those milestones actually mean for the overall electricity mix.
Here's what's genuinely true: according to ERCOT, the grid operator for most of Texas, wind and solar at certain moments in 2023 and 2024 supplied over 80% of instantaneous grid demand. Clean energy also surpassed coal in total annual generation for the first time, which BloombergNEF and Energy Monitor called a genuine milestone. Texas leads the entire U.S. in total wind power generation, and utility-scale solar has expanded rapidly. These are real achievements worth recognizing.
But here's where the claim falls apart. The EIA's Electric Power Monthly data shows natural gas still dominated the Texas grid in 2023, accounting for about 47% of all electricity generated. Wind came in at 26%, solar at 8%, nuclear at 11%, and coal at 7%. Record renewable peaks during favorable weather conditions don't change what the grid looks like on an average day, or on a hot summer evening when wind drops and demand spikes.
Ember Climate's analysis puts this in sharper context: Texas's grid carbon intensity — measured in grams of CO2 per kilowatt-hour — remains well above states like Washington, California, or New York, which rely more heavily on hydro, nuclear, or renewables throughout the year. Setting a record for how clean the grid was at its best moment is not the same as having a low-carbon grid overall.
The honest summary is this: Texas is making faster progress on renewables than most people expect, and the records it set are real. But the grid as a whole is still heavily fossil-fueled, and framing it as 'record low-carbon' misleads people about how much work remains. Watch for claims that highlight peak or instantaneous grid performance — they can be technically accurate while painting a very incomplete picture.

- U.S. Energy Information Administration (EIA)
Texas (ERCOT) has significantly expanded renewable energy capacity, with wind and solar generation reaching record highs in recent years, but natural gas still dominates the grid, typically supplying 40-50% of electricity generation.
- ERCOT (Electric Reliability Council of Texas)
ERCOT reported record renewable energy output milestones in 2023-2024, with wind and solar at times supplying over 80% of instantaneous grid demand, but annual average carbon intensity remains substantial due to fossil fuel baseload.
- EIA Electric Power Monthly
Texas leads the U.S. in total wind power generation and has rapidly expanded utility-scale solar, but total CO2 emissions from Texas electricity generation remain among the highest of any state due to the sheer scale of fossil fuel use.
- BloombergNEF / Energy Monitor
Texas set records for renewable energy generation in 2023, with clean energy (wind + solar) surpassing coal in annual generation, representing a genuine milestone, though the claim of 'record low-carbon electricity production' overstates the overall carbon profile of the grid.
- Carbon Tracker / Ember Climate
While Texas has made notable strides in low-carbon generation, its grid carbon intensity (gCO2/kWh) remains well above states like California, Washington, or New York, which rely more heavily on hydro, nuclear, or renewables year-round.
