Green PCs and Optimizing their Lifecycle
Let me be the first to confess: I love my laptop. I spend more time with it than most people in my life, including family, room mates, and boyfriend. I might even go so far as to admit an unhealthy infatuation with the Internet, writing, and a handful of computer games. Yet as an aspiring environmentalist, my electronic sidekick poses an uneasy paradox. How do I lay claim to “green” (whatever that really means) when I spend so much of my time plugged in?
Computers aren’t very environmentally friendly. They contain lead, mercury, cadmium, lots of plastic, and they thirst for electricity. Most people don’t realize that most of a computer can be recycled, so most discarded computers head to the landfill where the heavy metals can contaminate local water and air. Computers and electronics have become disposable in our culture, so the amount of electronic waste generated each year is astounding. Fortunately these are not problems without solutions. Starting from the beginning of a computer’s life to its demise, it can be easy to optimize everything about your PC.
Buying, Building, and Design
With the new popularity of green, critics have been quick to turn on companies like Apple for pumping out so many gadgets. The good news is that companies have been quick to respond with energy-efficient models, recycling programs, and improved design. Many “green” initiatives focus on energy efficiency but ignore manufacturing or end-life issues, so be wary of their “environmental” credentials. If you find a product or company that can vouch for the creation, use, and disposal of their products, you’ve struck gold. The good news is that newer models use fewer harmful chemicals and metals, require less energy, and improve performance. Lean, and mean is the angle many companies are aiming for with “green” patched on to sell. Laptops are the best example of this trend as they become smaller and more powerful simultaneously. So rest easy knowing that if you must buy a new computer, it will probably be more efficient than your old one… assuming you don’t hook a brand new 60-inch flat screen to it.

By now, most of us know that leaving our computers on when we’re not using them wastes energy. But exactly how much energy?
