When the Taiwan Energy Service Association (TESA) was founded in 2005, it had only 30 members, most of which were sellers of chilled-water systems, air conditioners, and lighting equipment that were seeking to move into a new field. Interestingly, the current recession has been a boon to local energy service providers. Taiwan's export-dependent manufacturers have been suffering from reduced order volumes since the recession got underway.
相較之下，台灣的發展較慢，2005 年成立的能源技術服務商業公會，一開始只有 30 家會員，大多為銷售冰水主機、空調與照明設備的廠商轉型投入；去年全球金融海嘯襲擊，景氣低迷，造成依賴出口的台灣製造業訂單緊縮。
