UPSC Syllabus Topic:<\/strong> GS Paper <\/strong>3-<\/strong>infrastructure- energy And Environment<\/p>\n

Context<\/strong>: Jellyfish swarms<\/strong> in unusually warm northern European waters shut two French nuclear plants<\/strong> by clogging cooling intakes. This headline failure anchors the article\u2019s argument: extreme heat strains generation, water, transmission, wind, and data-centre cooling<\/strong>, while solar and batteries help only partly.<\/p>\n

Jellyfish Shutdowns and Heat-Driven Failures<\/strong><\/h2>\n
    \n
  1. French nuclear intake clogging:<\/strong> Jellyfish blocked reactor intakes, forcing shutdowns. Other units may cut output<\/strong> because the Rh<\/strong>\u00f4ne and Garonne<\/strong> are too warm for safe cooling.<\/li>\n
  2. Iraq<\/strong>\u2019<\/strong>s demand surge in extreme heat:<\/strong> During Arba<\/strong>\u2019<\/strong>in<\/strong>, demand for fans and air-conditioners surged as temperatures topped 40 <\/strong>\u00b0<\/strong>C<\/strong>. Supply to most of Iraq<\/strong>collapsed.<\/li>\n
  3. Backup equipment overheating:<\/strong> At the Cincinnati Open<\/strong>, an on-site generator apparently overheated<\/strong>, causing a power outage and suspending play.<\/li>\n<\/ol>\n

    Thermal Generation Loses Efficiency in Heat<\/strong><\/h2>\n
      \n
    1. Design limits surpassed: <\/strong>Energy assets are built for narrow temperature bands. A warming climate pushes them beyond those limits when demand peaks.<\/li>\n
    2. Forced-outage probabilities<\/strong>: Heatwaves raise failure risks: coal +3.2 percentage points<\/strong>, gas +1.3<\/strong>, nuclear +1.0<\/strong>, according to Sweden\u2013Italy researchers.<\/li>\n
    3. Severe output loss case: <\/strong>An Iraqi gas plant lost ~21%<\/strong> of potential output as ambient temperature rose from 25 <\/strong>\u00b0<\/strong>C to 50 <\/strong>\u00b0<\/strong>C<\/strong>.<\/li>\n<\/ol>\n

      Cooling Water Scarcity Deepens Risks<\/strong><\/h2>\n
        \n
      1. Heatwaves, drought, and coolant shortages: <\/strong>Thermal plants must dump waste heat<\/strong>. Warmer air and water make cooling harder and less available.<\/li>\n
      2. India<\/strong>\u2019<\/strong>s shutdowns and local strain:<\/strong> Since 2014<\/strong>, India has lost 19 days<\/strong> of coal power to water shortages<\/strong>. Many communities turn to tanker trucks and deeper boreholes.<\/li>\n
      3. Rising competition with drinking needs: <\/strong>By 2050<\/strong>, power stations may pressure water supplies<\/strong> more than drinking needs<\/strong>, government forecasts warn.<\/li>\n<\/ol>\n

        Renewables and the Grid Under Heat<\/strong><\/h2>\n
          \n
        1. Wind lulls in hot spells<\/strong>:<\/strong> Hot conditions often cut wind speeds. The affected area has grown 6.3% per decade<\/strong> since the early 1980s; about 60% of the planet<\/strong> is now at risk.<\/li>\n
        2. Regional wind variations: Australia, Siberia, and Europe<\/strong> can see 30%\u201350%<\/strong> declines during heatwaves. The northern US, east Africa, the Amazon, and western China<\/strong> sometimes see the opposite.<\/li>\n
        3. Transmission and transformer stress: <\/strong>Cables and transformers heat under load<\/strong> as air temperatures rise. Failures become more likely during AC-driven demand spikes<\/strong>.<\/li>\n<\/ol>\n

          Data-Centre Demand and the Outlook<\/strong><\/h2>\n
            \n
          1. Cooling loads at data centres:<\/strong> About one third<\/strong> of data-centre electricity goes to heating and cooling. A 2022 heatwave<\/strong> shut server racks at two London hospitals<\/strong>, disrupting IT.<\/li>\n
          2. Relative resilience of solar and batteries: Solar PV and lithium-ion batteries<\/strong> are more heat-resilient than thermal plants and wind, offering partial relief<\/strong>.<\/li>\n
          3. Enduring legacy:<\/strong> Industrial systems rely on a moderate climate<\/strong> now disrupted by fossil emissions. The damage from fossil technology<\/strong>will persist<\/strong> even after cleaner power spreads.<\/li>\n<\/ol>\n
