The Dazzling Evolution of Energy-Efficient Lighting

Here's a bright idea: light bulbs that use 75% to 80% less energy.

Compact fluorescent bulbs (CFL) and light-emitting diode bulbs (LED) are quickly becoming the new norm. These newer bulbs have a bright future since the U.S. Government passed the Energy Independence and Security Act of 2007, which requires a systematic reduction of inefficient incandescent bulbs, culminating in 2014.

Currently, CFLs — the spiral-shaped bulbs — are the leading alternative to incandescent bulbs. LED bulbs are the longest lasting of them all, but they come at a significantly higher cost compared to CFLs.
