位於美國德州奧斯丁的公營能源公司──奧斯丁能源公司,在2000年發起的環保選擇(GreenChoice)能源計畫,供選擇環保發電的用電戶能夠獲得獎勵金。適逢2005年秋季天然氣價格的上漲,造成傳統發電成本高過佔環保電力多數的風力發電,這項相對成本高低的互換,成為了美國轉換使用再生能源的契機。
INSIGHTS: Wind Energy Demand Booming: Cost Dropping
When Austin Energy, the publicly owned utility in Austin, Texas, launched its GreenChoice program in 2000, customers opting for green electricity paid a premium. During the fall of 2005, climbing natural gas prices pulled conventional electricity costs above those of wind-generated electricity, the source of most green power. This crossing of the cost lines is a milestone in the U.S. shift to a renewable energy economy.
