因為,在「智慧電網」(Smart Grid)誕生後,這些輸出電力的插座,未來可以上網、控制電器、甚至能把家裡太陽能電板所生的電力,回傳給電力公司;小小的插座,搖身一變,成為全球最夯的科技話題。

智慧電網是電力傳輸技術的改變。現有的供電系統,無法分辨終端用電量大小,常造成浪費,智慧電網在供電時,可依不同時段的實際用量,調節分配,因而有節能效果。今年《時代》雜誌(Time)將智慧電網相關產品評選為年度十大發明之一;智慧電網相關概念股,是今年以來美國股市漲幅最高的類股;美國總統歐巴馬(Barack Obama)競選時對智慧電網的承諾,也在今年兌現。

NEW YORK (TheStreet) -- There has been a debate within solar circles over the past year concerning the fate of the solar industry's bellwether stock, First Solar(FSLR Quote), and that debate boils down to this: Is First Solar still a growth stock?

In May of 2008, First Solar was trading at over $311. On Wednesday, First Solar closed at $114.
