In the polarized realm of climate and energy politics, energy efficiency has always been the common ground. The concept is so attractive—we clearly waste far too much of our energy, whether that means driving a car with that gets low gas-mileage or living in a poorly insulated house. Here's what Evan Mills, a scientist at Lawrence Berkeley National Laboratory, said about the Journal paper:
More is not always better. For rich and poor alike, the sky (i.e., a burning sun in every living room) is not the limit for lighting demand. Illuminating engineering societies around the world have actually been reducing their lighting-level recommendations for many years running, as overzealous guidelines have been seen to create excessive glare and other problems. Even granting some pent-up demand for more lumens, LEDs can save energy because their light can be more precisely directed to end-use needs and more easily controlled.
