Evergreen Sky Catering, located near the Taoyuan International Airport, is a case in point. The company provides 220 tons of hot water per day to its kitchens and employee housing. It used to heat this water in two diesel-fired boilers, and paid through the nose when international oil prices rose.
以桃園國際機場附近的長榮空廚為例，每日供應廚房和員工宿舍熱水 220 噸，原來採用的是兩台柴油蒸氣鍋爐，自國際油價高漲後，油費支出龐大。
