Will lower, warmer rivers still be able to keep power plants cool?

A new paper* in the prestigious journal Nature Climate Change assesses the vulnerability of electrical supplies in the US and Europe to climate-change. Specifically to rising water temperatures and reduced river flows needed to cool thermoelectric plants—coal, gas, and nuclear powered.

Both the US and Europe rely heavily on thermoelectricity. Currently:

  • 91 percent of total electricity in the US is produced by thermoelectric plants
  • 78 percent of total electricity in Europe is thermoelectric
  • Together these plants represent ~86 percent of total thermoelectric water withdrawals globally
