Sustained periods of extreme heat across North America and Europe have precipitated systemic failures in power grids and public infrastructure, necessitating urgent adaptation strategies.

北美與歐洲持續出現的極端高溫，導致電網與公共基礎設施出現系統性失效，迫使相關部門必須採取緊急適應策略。

The intersection of anthropogenic climate change and aging infrastructure has rendered global energy networks susceptible to thermal stress. In the United States and Europe, the simultaneous surge in cooling demand and the physical degradation of hardware—such as the thermal expansion and subsequent sagging of transmission lines—have increased the frequency of outages. Data from Climate Central indicates a 60% increase in heat-related power failures in the U.S. over the last decade. Furthermore, thermal power plants, including nuclear, coal, and gas facilities, experience a precipitous decline in efficiency, estimated at 1% per degree Celsius of temperature increase, often necessitating output reductions to comply with environmental regulations regarding water discharge temperatures.

人為氣候變遷與老化基礎設施的交織，使得全球能源網絡容易受到熱壓力影響。在美國與歐洲，冷氣需求激增與硬體物理退化（例如輸電線因熱脹冷縮而下垂）同時發生，增加了停電頻率。Climate Central 的數據顯示，過去十年美國與高溫相關的停電事故增加了 60%。此外，包括核電、煤電與氣電在內的火力發電廠，效率會隨溫度每上升 1 攝氏度而急劇下降約 1%，通常為了符合排水溫度的環境法規，必須削減輸出功率。

Institutional responses have varied by region. In the U.S., grid operators such as PJM Interconnection have implemented emergency protocols, including the redirection of high-energy users like data centers to backup generation. Conversely, the United Kingdom has faced significant disruptions in public services; over 1,000 schools were closed in June due to inadequate ventilation and a lack of air conditioning in facilities designed for a colder climatic epoch. The Climate Change Committee has noted that without systemic retrofitting, indoor temperatures in educational institutions could reach 35°C with increasing regularity by 2050.

各區域的制度反應有所不同。在美國，如 PJM Interconnection 等電網營運商已實施緊急協定，包括將數據中心等高能耗用戶轉向備用發電。相反地，英國的公共服務面臨嚴重中斷；六月份有超過 1,000 間學校因通風不足，加上設施設計於寒冷氣候時代而缺乏冷氣，被迫關閉。氣候變遷委員會指出，若不進行系統性改造，到 2050 年，教育機構室內溫度達到 35°C 的情況將越來越普遍。

Proposed mitigations involve a transition toward 'smart grids' and enhanced flexibility. Experts suggest the implementation of hybrid cooling systems for nuclear plants and the deployment of battery storage to manage the diurnal mismatch between solar generation and peak evening demand. However, the realization of these upgrades is hindered by significant bureaucratic backlogs in renewable energy connections in Europe and chronic underfunding of public infrastructure in the UK. In the Arctic regions of Alaska, the phenomenon is compounded by permafrost degradation, which destabilizes the very foundations of the energy and transport infrastructure.

建議的緩解措施包括過渡到「智慧電網」與提升靈活性。專家建議核電廠應實施混合冷卻系統，並部署電池儲能，以管理太陽能發電與晚上用電高峰之間的時間不匹配。然而，由於歐洲再生能源接網存在嚴重的行政積壓，加上英國公共基礎設施長期資金不足，這些升級的實現受到阻礙。在阿拉斯加的北極地區，永凍土退化使情況更加複雜，直接導致能源與交通基礎設施的地基不穩。

Current global energy and public systems remain inadequately equipped to manage the increasing frequency and intensity of extreme thermal events.

目前全球的能源與公共系統，依然不足以應對日益增加的極端高溫事件頻率與強度。
