我先假設你是來認真學習的
我就認真地回你一下
CO2封存是對應火力發電產生的CO2
因為人類產生的CO2已經超過了環境的代謝率
所以現在科學家想到的方式就是想辦法捕捉火力發電產生出的CO2
然後向核廢料封存一樣 找個洞埋 只是因為是氣體所以就壓縮打到地底下而已
至於再生能源
我很認真的跟你說喔 生質柴油是所有目前所謂的綠色能源裡面
最先被捨棄的一個
第一 生物體的能源轉換率 導致淨輸出小於輸入 簡單就是玉米跟大豆生質柴油
為了生產這些東西反而更浪費了額外的能源,甚至包括了鈾礦
藻油 沼氣發電目前也是這樣子
第二 糧食排擠 這些發電用的作物因為需要大量栽種 排擠了原來的糧食種地
所以生質柴油已經是先被宣告死亡了
