iMac is designed to be energy efficient right out of the box. It has even earned the EPA’s ENERGY STAR qualification for its low power consumption.
Efficient power supply.
iMac includes a highly efficient power supply that reduces the amount of power wasted when bringing electricity from the wall to your computer. Lower power consumption reduces energy bills and lessens the environmental impact of greenhouse gas emissions from power plants.
Advanced power management.
Unlike a lot of Windows-based PC systems, iMac uses energy-efficient hardware components that work hand in hand with the operating system to conserve power. Mac OS X spins down hard drives and activates sleep mode on already
energy-efficient LED-backlit displays. And it balances tasks across both central processors and graphics processors. Mac OS X never misses a power-saving opportunity, no matter how small. It even regulates the processor between keystrokes, reducing power between the letters you type. That’s just one of many ways Apple manages small amounts of power that add up to big savings.
ENERGY STAR qualification.
iMac meets the stringent low power requirements set by the EPA, giving it ENERGY STAR qualification. ENERGY STAR 6.0 sets significantly higher efficiency limits for power supplies and aggressive limits for the computer’s typical annual power consumption.
Eliminating Toxic Substances
It’s what iMac doesn’t have that makes it more environmentally friendly. It’s free of many harmful toxins, including mercury, arsenic, BFRs, and PVC.
The greatest environmental challenge facing the computer industry is the presence of arsenic, brominated flame retardants (BFRs), mercury, phthalates, and polyvinyl chloride (PVC) in products. Apple engineers have worked hard to eliminate BFRs and PVC from iMac circuit boards, internal and external cables, connectors, insulators, adhesives, and more.1 And they’ve eliminated many other toxins that are a common part of desktop computer manufacturing — choosing, for example, mercury-free backlighting and arsenic-free glass for the iMac display.
Because iMac is made from materials such as aluminum and glass, it’s more likely to be recycled and reused at the end of its long, productive life.
Apple has minimized the waste when iMac reaches end of life through its ultra-efficient design and the use of aluminum and glass, which recyclers can reuse for other products.
Free recycling for your old computer.
If you live in the U.S., Apple offers a free recycling program for old computers and displays with the purchase of any new Mac. Learn more on the Apple Recycling site
