現在大部分油車與電車比較的新聞都不要很聳動
原因很多 譬如利益關係 記者製造話題等
小弟我曾做過一些關於生命週期的專題(Life Cycle Assessment,簡稱LCA)
就碳排放來說 要討論到的是碳足跡跟碳回收
如果要以碳足跡來討論環保
當一台車子被製造出來
它的原料、製程、能源等 從無到有總共花費了多少碳(我指的就是C)
石化能源也要算進生產 提煉 運送等碳成本
其中有多少是可以回收的?
所謂回收就像是 我們燒木炭產生CO2
但造林的時候 樹木成長中 CO2中的碳會被轉化為木質素 纖維素等固定回去
因此烤肉燒木炭以溫室氣體來說不環保是錯誤的 不環保的點在於空氣品質跟飄散物
順帶一提 樹木雖然早上會行光合作用 晚上也會改行呼吸作用 並不會減少我們的氣態碳
因此多砍樹做成木製品 再多造林反而可以減少溫室氣體
這部分在台灣是環保團體不願意面對的真相
時代在進步 雖然是為了看不見的未來 永續經營還是有它的價值跟意義
但以我國發電結構來說 要談再生能源還太早
因此需要計算的就是燃燒效率了
以都會區來說 內燃機的燃燒效率非常低
那些燃燒效率的漂亮數據基本上就是跟最高油耗比的做法是一樣的
什麼40%的別鬧了 實際應用上效率就是非常低
那電能車優勢在哪?
電能車目前的優勢主要就是在都會區使用中
相對高出許多的燃燒效率 以及 人口高密度區空氣品質的控管
在未來電能車會逐漸成為主流 多久的未來不知道
因為電池技術(便利性) 跟 發電結構(實質環保) 都還有很大的空間可以進步
但低耗能的車種絕對會先出現這狀況 (燃油機車別轟我QQ)
