New Analysis Reveals Massive Water Use by Texas Power Plants

A recent analysis by the Sierra Club has uncovered the extensive water consumption by Texas’s thermal power plants, highlighting a significant environmental concern amid ongoing water scarcity in the state. The report reveals that gas, coal, and nuclear plants in Texas collectively use approximately 100 billion gallons of water annually, with gas plants alone accounting for 56 billion gallons. In stark contrast, renewable energy sources and battery storage systems require negligible water, underscoring the inefficiency of traditional power generation methods in terms of water use. The Sierra Club’s findings, drawn from a decade of Energy Information Administration data, also emphasise the disproportionate water rights held by coal plants, which are permitted to withdraw up to 116 billion gallons yearly and can store nearly 98 billion gallons in reservoirs. This volume of water is equivalent to the annual needs of one million Texas households, or the capacity to fill tens of thousands of Olympic-sized swimming pools, illustrating the scale of water diverted to energy production. Despite coal providing just 12% of the state’s electricity, it consumes nearly a third of the water used for electricity generation, while gas plants, supplying over half of Texas’s power, use close to half of this water. Sierra Club representatives have voiced strong criticism of the current system, calling for urgent reforms to reduce water use in the energy sector. Lindsay Mader, a report author and local resident, highlighted the paradox of increasing water scarcity alongside continued heavy water use by fossil fuel plants, especially when cleaner, low-water alternatives are available. The organisation urges Texas lawmakers and regulatory bodies to prioritise renewable energy and battery storage solutions, which could significantly alleviate pressure on the state’s water resources. Environmental experts involved in the report also warn of broader ecological impacts, noting that excessive water withdrawals by power plants exacerbate the state’s water crisis and threaten aquatic ecosystems. Alex Ortiz, a water law specialist, stressed the importance of reallocating water rights to support environmental protection and maintain biodiversity in Texas’s rivers and estuaries. The Sierra Club’s analysis calls for a strategic shift in water management policies to balance human and environmental needs more effectively, particularly as climate change intensifies water stress in the region.
