LEDs not neccesarily eco-friendly

If, by “LED” one means “people.”

While the potential for cheaper energy could increase the quality of life for billions around the globe, it also could mean an increase in energy usage. Tsao says that since the 16th century, with each revolution in lighting technology humans have used more light, instead of using the same amount of light for cheaper.

“Over the past three centuries… the world has spent about 0.72 percent of the world’s per capita gross domestic product on artificial lighting,” said Tsao. “This is so for England in 1700, in the underdeveloped world not on the grid and in the developed world using the most advanced lighting technologies. There may be little reason to expect a different future response from our species.”

So let’s blame the LEDs for human nature and the law of supply and demand.
