And the cozy candles that many participants will light, which seem so natural and environmentally friendly, are still fossil fuels – and almost 100 times less efficient than incandescent light bulbs. Using one candle for each switched-off bulb cancels out even the theoretical CO2 reduction; using two candles means that you emit more CO2.
而很多参与者将点亮温馨的蜡烛，虽然看上去是如此地自然环保，但蜡烛终归是化石燃料——而且其照明效率仅相当于白炽灯泡的不到百分之一。关一盏灯点亮一支蜡烛就会抵消理论上的二氧化碳减排；而点亮两支蜡烛则意味着二氧化碳排放升高。
