With the introduction of EPEAT Gold rated MacBooks and MacBook Pros last week, Apple has definitely been warming up to the environmental movement lately. So, it was only fitting that they would change a small part of System Preferences to reflect the EPEAT rating.
That's right, the Energy Saver icon has changed from an old incandescent bulb to a newer, more energy-efficient fluorescent bulb. Now you will only have to change the energy saver icon every 7 years, but be careful when you dispose of the old icons because they contain mercury (just kidding).
This change has only shown up on the new MacBooks and MacBook Pros. Do you think Apple will eventually update their entire line to have this new icon (and, of course, be EPEAT Gold rated)? We definitely hope so!
Thanks to everyone who sent this in!
