Apple recently released their new line of MacBook and MacBook Pro laptops, which are mainly made from aluminium. They say that they are their greenest latops ever and claims that they are “highly recyclable and even more energy efficient”, and that they are “designed with the environment in mind”.

But really, how green are the new laptops?

Greenpeace, who is running a hard and successful campaign for greener electronics, says that the new laptops are “not quite the breakthrough” they “were hoping for”:

“A check of the full specs revealed the MacBook Pro, MacBook and MacBook Air – as well as the LED Cinema Display will now have internal cables free of PVC and will have internal components containing no BFRs. Not quite the breakthrough we were hoping for. These new MacBooks are currently on a similar level of toxics reduction to the Sony Viao laptop series on PVC, and the Lenovo Think Vision in monitors. The BFR free internal components represent an improvement from the bar set by the Vaio line.”

Hank Green, over at EcoGeek, is a bit more negative saying the new laptops are “wasteful”:

“I’m glad to see Apple focusing on the efficiency of their computers, not to mention decreasing the amount of toxic materials they contain. But this new carved-brick process isn’t green, it’s wasteful, and I’m happy to be sticking with my good-ol’ plastic clunker.”

Jaymi Heimbuch, from TreeHugger, on the other hand is a bit more positive:

“It seems that this process allows the MacBook Pro to use 50% fewer parts. In the manufacturing stage, they start with a 2.5 pound piece of aluminum. The end structure is only 0.5 pounds (for the MacBook Air). That means that 2 pounds of aluminum is cut away.

Nevertheless, it looks like this process, despite flaws, has some real improvements for the notebook in the big picture of its lifetime and total footprint.”

Apple explains how green their MacBook and MacBook Pro are on their website.

Lenovo recently released the ThinkCentre A61e, a brand new green computer. The ThinkCentre A61e uses few hazardous materials, consumes little power and is easy to recycle. Because of that it has received the desirable EPEAT Gold status.

Peter Schrady with the really long title of vice president and general manager, Emerging Products Business Unit says that “the importance of maximizing energy efficiency and being environmentally conscious is touching all aspects of our daily lives, from the light bulbs we use to light our homes to the hybrid cars we drive to the green technology we rely on to run our businesses.”

Un-customized it uses an AMD Sempron LE 1150 processor, 512MB ATI Radeon X1200, 512MB Memory, 80GB hard drive and costs $399. Not too shabby. Sure the computer is ugly (or shall we say retro?) but it’s still one of the more high performing green computers out there.

According to Lenovo using the energy-efficient AMD Athlon X2 dual core and AMD Sempron single core processors can help save up to 50 percent in energy costs annually.

Another good thing is that Lenovo ranks high in the Green Electronics Guide from Greenpeace. They are currently on the 4th place being beaten only by Dell (on third place).
