Christmas lights more efficient nowdays
Christmas lights galore. This house along one of my favorite bike routes across town.
I remember government officials asking people, back in the 1970s, to have less Christmas lights.
Now there is less guilt, partially due to light emitting diodes. They use much less power for same amount of light.
Inventor of light emitting diode was recently on NPR Science Friday show. He was discussing the art of invention. Started working with the concept in 1962.
I remember "sterio light" would come on in a hifi amplifier of the 1970s. That was my first experience of light emmitting diodes. Now thay come in many colors.
If we can't change our consumptive ways, maybe technology can patch the problem for us.
Don't worry, be happy.
Actually, I like technology and innovation. It is what saves us as world circumstances change.
