Korea Shines for Compact Fluorescent Use
At night, South Korea is literally aglow. When the sun goes down you’ll find a vibrant night life of kareoke (”norebang”), street markets, and sujo bars. Still, per person, Koreans use only a little over half the energy used in the United States. How do they manage to light up the night–every night–and still save energy?
Part of the answer might be South Korea’s high usage of compact fluorescent light bulbs (CFLs).
It took me almost two months of living in Korea before I saw my first incandescent (”old fashioned”) light bulb. All of the others were energy efficient CFLs, like the one pictured here at this outdoor market.
Have you heard this one before? "A light bulb walks into a bar…" Wait, that's not right. Let's try it again, "What's bright and light and white all over?" Okay, we're not the best joke tellers in the world, but we do know the punchline: CFL.
