This report examines the differences in how North America and Europe manage indoor temperatures, the role of renewable energy in stabilizing electricity prices, and the challenges facing the European power grid.

本報告探討了北美與歐洲在室內溫度管理上的差異、可再生能源在穩定電價方面扮演的角色，以及歐洲電網所面臨的挑戰。

The difference in how people cool their homes in America and Europe is based on different building styles and cultural views on the environment. While American homes rely heavily on air-conditioning, Southern European buildings traditionally used natural methods, such as shaded courtyards and shutters. In Northern Europe, the use of air-conditioning has been limited by cooler climates and a desire to avoid high energy consumption.

美國與歐洲人們在居家降溫方式上的差異，源於不同的建築風格以及對環境的文化看法。美國房屋高度依賴空調，而南歐建築傳統上則使用自然方法，例如遮陽中庭與百葉窗。在北歐，由於氣候較冷且希望避免高能耗，空調的使用相對有限。

However, climate change and the El Niño phenomenon have forced a change in these habits. The growth of renewable energy has significantly lowered the carbon emissions of the European power sector. For example, solar power in Spain has increased nearly ten times over the last decade, which has greatly reduced CO2 emissions compared to US levels. Furthermore, natural gas has a much smaller effect on electricity prices; in Spain, gas influenced pricing only 9% of the time in early 2026, compared to 52% in 2021.

然而，氣候變遷與聖嬰現象迫使這些習慣發生改變。可再生能源的增長顯著降低了歐洲電力部門的碳排放。例如，西班牙的太陽能電量在過去十年增加了近十倍，與美國水平相比，大大減少了二氧化碳排放。此外，天然氣對電價的影響已大幅降低；在 2026 年初，天然氣對西班牙定價的影響僅為 9%，而 2021 年則為 52%。

Geopolitical instability, such as the conflict involving Iran, has shown that moving away from fossil fuels protects countries from price swings. While the EU spent about €60 billion on fossil fuel imports, Spanish households actually saw a drop in electricity costs. This happened because wind and solar power grew by 37% between 2021 and 2025, protecting consumers from global fuel shocks. In contrast, countries like Poland and Germany still rely more on carbon-heavy fuels, making them more vulnerable to market changes. Despite this, the EU still invests too little in electrification—less than 5% of what it spends on fossil fuel imports. To stay competitive against China and support AI technology, Europe must modernize its grids and improve battery storage.

地緣政治不穩定（如涉及伊朗的衝突）顯示，脫離化石燃料能保護國家免於價格劇烈波動。雖然歐盟在化石燃料進口上花費了約 600 億歐元，但西班牙家庭的電費實際上有所下降。這是因為風能與太陽能在此期間（2021 年至 2025 年）增長了 37%，使消費者免受全球燃料衝擊的影響。相比之下，波蘭與德國等國仍較多依賴高碳燃料，使其更容易受到市場變動的影響。儘管如此，歐盟在電氣化方面的投資依然不足——不到化石燃料進口支出的 5%。為了在與中國的競爭中保持優勢並支持 AI 技術，歐洲必須將電網現代化並改善電池儲能。

Europe is moving toward a model of clean and affordable cooling, but achieving full stability will require more investment in power grids and renewable energy.

歐洲正趨向於一種乾淨且可負擔的降溫模式，但若要實現全面穩定，仍需對電網與可再生能源增加投資。
