這篇Forbes 2016年的文章用了一個很棒的例子解釋：
—————————————-
假設你和9個人一起搭船從A地航行到B地，其中10%時間這艘船透過船帆利用風力航行，另外90%則是燃燒柴油用引擎推動。
Apple的作法就是 — 花錢跟這9個人買「他們的10%風力時間憑證」，然後對外聲稱「自己100%靠風力到達B地」。
（Think of it this way. Imagine you and 9 other people are traveling on a yacht that has both sails and a diesel engine. For the 10% of the time that the wind was blowing perfectly in the right direction, the yacht would use the sails. For the other 90% of the time, the diesel engine would do the heavy lifting. Now imagine that, after the trip, you want to claim that you traveled the entire distance by sail, so you pay every other passenger $10 for the right to claim that you used their 10% sail time. You get to claim that you sailed 100% of time, while the other passengers have to say they used the “dirty” diesel engine for their entire trip. That’s basically what Apple is doing with their energy accounting sleight of hand.）」

這樣講應該很容易理解「綠電認購憑證」是怎樣的東西。也知道Apple等聲稱環保的大廠在搞什麼鬼。
更知道Emmy Hu這種大媽偽財經專家妖言惑眾欺騙大眾「不搞風力、太陽能發電蘋果就不下單」的謊言何在。
還有兩個重點：
1. 太陽能與風電因為發電不穩定的關係，根本不可能直接拿來作為工廠使用的電。會相信這種蠢論點的人，恐怕是連塑膠射出成形機都沒見過的大外行。
（很難想像供電不穩下，塑膠射出成形機如何維持溫度穩定射出，模流的塑膠溫度不穩簡直是一場災難，枉論穩定品質生產）
2. 延續我前一篇文章，考量土地邊際生產力，太陽能與風電在台灣這種地方根本是「最不環保」的生產方式！浪費大量土地資源結果只不穩地生產一點點電。
