剛去查原料這方面
原來半導體 跟 太陽能板 光纖 的原料
都是用 高純度的石英礦物
這東西還超稀有
主要是北卡 Spruce Pine (Sibelco)
還有挪威TQC 跟其他少數地區才有
2014年 全地球儲存量約9500萬噸
2019年 就剩下 7500萬噸
2023年 查不到 但應該更少
最近價格狂噴
所以之前有些人說 太陽能板只要1%國土面積
就能供應全美 全歐 根本唬爛
材料根本不夠咧
這東西做成成品後也無法回收
按照這趨勢
感覺撐不過50年 甚至 30年....
另外 人類最常用的 最便宜的礦物之一 「 鐵礦石」
地球目前儲量是1900億噸
去年消耗約26億噸 後面還會增加(扣除回收)
除下來 感覺也撐不過100年......
後期因為開採成本會極高 而大幅墊高成本
常用的還有 鋁 銅 鎳 鎂 鈉 鉀 碳 硫 煤
這樣看下來 100年後 應該就得慢慢回到 某種新型的農業時代?
