Apple has unveiled it’s greenest MacBook yet, producing a new system which is made from a single piece of solid, recyclable aluminum, as well as a display made of recyclable glass.

The company has also removed many of the harmful toxins found in computers including mercury, arsenic and PVC. And, to reduce energy consumption, the MacBook hard drive spins down automatically when inactive, using 30 % less power than previous models. The MacBook also decides which processor — CPU or GPU — is best suited to efficiently perform a task. The processor even throttles down to save power between keystrokes as you type.

Apple also cut out nearly half of the bulky packaging to streamline their distribution and create less waste.
