Lights

The US (like many other nations, China included) has been phasing out incandescent light bulbs: 100-Watt bulbs starting in late 2012, 75-Watt bulbs during 2013, and 40- and 60-Watt bulbs during 2014. The US efficiency standard driving this is for bulbs yielding 310-2600 lumens. Europe phased them out earlier.

The primary alternatives are compact fluorescent lights (CFLs), later light-emitting diodes (LEDs). Savings from efficient lighting (better ballasts, reflectors, etc.) are even larger in the commercial sector.
