Environmentalist groups and celebrities are celebrating “Earth Hour” Saturday night. They ask that you turn your lights out for an hour, to call attention to global warming.

Folks at the Competitive Enterprise Institute suggest that “this sends the wrong message—to plunge us all into darkness as a rejection of technology and human achievement.” In fact, they point out that it’s Earth Hour every night in North Korea, where people lack basic freedoms, as well as affordable, reliable access to many human achievements, such as electricity. Check out this famous photo of environmentally conscious North Koreans observing Earth Hour all night, every night.

CEI rejects the rejection of technology. They have declared the hour between 8:30 and 9:30 on Saturday, March 31, to be “Human Achievement Hour.” To join the celebration, just turn your lights on and enjoy the human achievement of light when we want it.

I’ll be celebrating Human Achievement Saturday night. However, I do expect the lights to go out all over Louisville about 8:30 on Saturday night, as the Kentucky Wildcats shred the Louisville Cardinals in the Final Four.
