Cooling Costs & Conservation Options
A new report shows Texas power plants use approximately 100 billion gallons of water annually. Gas, coal, and nuclear facilities are the biggest consumers. This usage occurs despite the availability of water-saving technologies. The Sierra Club released the analysis on May 6, 2026.

The process creates steam to drive turbines, generating electricity. However, a significant portion of this water is lost through evaporation. This places strain on already stressed water resources in Texas.
The report highlights that many plants continue to rely on older, less efficient cooling systems. These systems require significantly more water than modern alternatives. Dry cooling and hybrid cooling technologies reduce water consumption. They offer viable options for many Texas facilities. Implementing these changes could lessen the burden on the state’s water supply.
Can Texas Balance Energy Needs with Water Security?
Researchers found a clear pattern. Older plants, particularly coal-fired facilities, exhibit the highest water usage rates. Newer gas plants generally use less water. However, the cumulative impact of all thermal plants remains substantial. The analysis points to a need for updated regulations. These regulations should incentivize water conservation in power generation.
Texas faces a growing challenge balancing its increasing energy demands with dwindling water resources. Population growth and climate change are exacerbating the problem. Droughts are becoming more frequent and severe, reducing water availability. The power sector’s high water consumption adds to this pressure.
The report suggests that transitioning to renewable energy sources like solar and wind could significantly reduce water stress. These technologies require minimal water for operation. Investing in water-efficient cooling technologies at existing plants is also crucial. A comprehensive approach is needed to ensure a sustainable energy future for Texas.
Frequently Asked Questions
What is „thermal power”? Thermal power plants generate electricity by heating water to create steam. This steam then spins turbines connected to generators. Gas, coal, and nuclear plants all fall into this category.
Why is water use a concern for power plants? Power plants use water for cooling. This process releases heated water back into the environment. High water consumption strains limited resources, especially during droughts.
Could switching to renewables solve the problem? Renewable sources like solar and wind require very little water to operate. A shift towards these technologies would substantially reduce the power sector's water footprint.
