For instance, if you wanted to reduce world energy consumption by 1 %, if you turned to the IT industry (which accounts for 2 % of the world's energy consumption) they would have to make a huge 50 % cut in power use. In contrast, this goal could easily be reached by increasing the efficiency of electric motors by just 2 %.
他舉例，台灣最夯的資訊業只占全球能源消耗量的 2 %，就算全部資訊產品的能源效率都一舉提高 50 %，也總共只能省下 1 % 的能源；反觀馬達效率只要增加 2 %，即可輕易達到這個目標。
