Based on studies in Japan, when consumers go from "being concerned only about the bill" to being "conscious of their consumption of energy," reductions of more than 20 % can result. This would be of tremendous assistance in battling the greenhouse effect and other environmental ills.
依據日本的經驗，消費者若從「只關心帳單」轉成「自覺性使用能源」，可以有效節約能源達百分之二十以上，對於減少溫室效應等環保需求助益極大。
