An open model of Taiwan's electricity system台灣電力系統的開放模型
What does it take to keep Taiwan's lights on, and cut its emissions? 要讓台灣穩定供電、同時減少排放，需要什麼？
Taiwan imports 99% of its energy, runs an island grid with no links to its neighbours, and must grow its supply for a booming chip industry while moving away from coal. This site uses an open-source model (PyPSA-Earth) with official Taiwanese data to explore these questions: hour by hour, over a full year. 台灣 99% 的能源仰賴進口，電網是無對外聯網的孤島，還要在減少燃煤的同時，為蓬勃發展的半導體產業增加供電。本網站以開源模型（PyPSA-Earth）與台灣官方資料，逐時模擬一整年，探討這些問題。

Sandbox: what if…?情境沙盒：如果……？
Add offshore wind, restart nuclear, retire coal, cap CO₂ or change prices, and see cost, emissions and supply security, with uncertainty ranges.增加離岸風電、重啟核電、燃煤除役、設定 CO₂ 上限或改變價格，查看成本、排放與供電安全，並附不確定性範圍。
Energy security: blockade能源安全：封鎖情境
If fuel ships stop arriving for 14 to 60 days, how much electricity can Taiwan still supply with its LNG, coal and oil stocks, and what helps?若燃料船 14 至 60 天無法抵達，台灣靠液化天然氣、燃煤與燃油存量還能供應多少電力？哪些措施有幫助？
Taiwan's energy challenges台灣的能源挑戰
Import dependence, an island grid, the north–south imbalance, nuclear phase-out, growing demand and the path to net zero.進口依賴、孤島電網、北電南送的不平衡、非核、用電成長，以及邁向淨零之路。
