Europe’s blistering heat wave is threatening energy security across the continent as power plants shut down and the risk of rolling blackouts rises. Electric grids are overstressed, and ecosystems are too. Rivers are greatly affected by soaring temperatures, which in turn impacts the energy industry and power plants that rely on that water supply for their cooling systems. Just this week, France announced that it will reduce production at as many as five nuclear power plants, with two already curbing output this week.France is expected to receive the worst of a coming high-pressure heat dome over the next few weeks, with temperatures soaring to as high as 42 Celsius (107.6 Fahrenheit) in some parts of the country on Wednesday. When Europe experienced a similar heat wave last month, a transformer failed, leaving nearly 70,000 households without power as temperatures reached deadly levels. The country recorded its hottest day ever on record, with temperatures reaching a blistering 44 °C (111 °F).These temperatures are not only deadly to humans, they are also a huge threat to the ecosystem. Rivers are growing hotter under these conditions, and one of the impacts of that change is that their waters are no longer as effective for cooling down nuclear power plants, which serve as the backbone of France’s energy mix. As a result, the country anticipates needing to curb production at plants around the country at the very same time that demand is surging.Set OilPrice.com as a preferred source in Google here.It’s a sad irony that just as electricity is needed more than ever to keep indoor temperatures at survivable levels, the power grid is most likely to fail. "As it gets hotter, things stop working quite so well," Iain Staffell, associate professor of sustainable energy at Imperial College London, was recently quoted by DW. "I think we do need to adapt the power system to cope with the changing weather," he went on to add.The reduction of nuclear power output in France could greatly affect energy availability and affordability within France and in neighboring countries such as Germany and the United Kingdom, which import electricity generated by the nation’s sizable nuclear power sector. And nuclear is only part of the story. The heat wave is also impacting the output of hydropower and limiting the cooling abilities of coal and gas plants.Europe can expect this kind of strain to be the new normal as global warming alters climatic patterns around the world and increases the frequency and intensity of extreme weather. Policies will need to be put into place, and enacted quickly, in order to prepare European grids to withstand these kinds of temperatures at regular intervals going forward.“Utilities can adapt by planning for summer peaks, making cooling demand more flexible, reinforcing grids for high temperatures, deploying batteries and demand response, and climate-proofing power plants’ cooling systems,” Simone Tagliapietra, senior fellow at Bruegel, an economic and policy think tank, recently told MIT Technology Review via email.However, all of these imperatives are massively costly and difficult to implement, leading to inaction on the part of European leadership and widespread vulnerabilities of the continent’s energy infrastructure. Last year, the European Environment Agency reported that all 27 countries in the European Union have climate adaptation plans, but noted that “insufficient long-term funding” has stifled implementation.This has led to frustration and resentment amongst the public, not to mention over 1,000 unnecessary deaths. “Everyone is asking, why are we not ready?” Francois Gemenne, an environmental politics professor at French business school HEC Paris, recently told the New York Times. “We are becoming aware of our own vulnerability.”By Haley Zaremba for Oilprice.comMore Top Reads From Oilprice.comBureaucracy Is Strangling America's Clean Energy BuildoutSummer Heatwaves Are Rewriting the Rules for Britain's Power GridKazakhstan Extends Petroleum Export Ban Six Months as Hormuz Tensions Flare
