Lighting accounts for about 7% of the total electricity consumed in the US. Since lighting is often far removed from the power source—such as the distance from a power plant to street lamps on a remote highway—a lot of energy is lost during transmission.
在美国，照明约占总耗电量的7%。由于照明通常远离电源——例如从发电厂到偏远公路上的路灯——因此大量的能源在传输过程中会损失掉。
