Cheap Green Computer Runs on 2 Watts

Michelle Bennett — Mon, 30 Jun 2008 03:30:45 +0000

As far as green gadgets go, this little desktop computer will give Dell and (to a lesser extent) Apple a run for their money.

The CherryPal promises to be affordable, efficient, and powerful enough for the average PC user. At first glance, that stats on the system look modest, and for good reason. This design actually cuts out 20% of PC components to reduce energy usage. But fear not, despite being small (the size of a paperback), the CherryPal claims it can start up in 20 seconds, and cloud computing provides more power/storage when you need it. A Linux operating system (now more user friendly than ever), and cloud computing means you won’t need to worry about viruses or install protective programs that can slow down your PC.

Smart Power Strips the Garlic of Vampire Electronics

Michelle Bennett — Sat, 03 May 2008 13:15:31 +0000

I cover a lot of upcoming or future technology, but it’s time to step into the present and aim for the past. Today we’re going to look at a technology available right now that can make some wanton energy waste history. It’s a surge protector that stakes the hearts of vampire electronics without hassling you, the sleeping victim.

Vampire appliances are pretty much anything you can plug in that still sucks energy when it’s supposedly turned off. Some are pretty obvious - the clocks on your microwave or VCR/DVD player burn all day, everyday. We know they’re not “off” because we cans see their LEDs glow. But other electronics, from your television to your cell phone charger also draw power when they’re plugged in but not in use. Check out a handy graph from Good Magazine. Some gadgets are notorious, like your plasma TV. Estimates claim that 5% or more of U.S. energy usage is insidiously wasted by “stand-by mode” or certain misleading “off” buttons. A whopping 5% may not sound like much, but it adds up to about $1 Billion dollars per year - and energy prices will probably continue to rise.

Be honest - how many times would you go around the house unplugging everything before it got old? Smart greenies have been switching off their surge protectors, but it’s easy to forget while watching your favorite late-night TV show or blogging at 4am. So what can we do about these metal-toothed Nosferatu in our midst? How about a surge protector that turns off all your appliances for you?

Green PCs and Optimizing their Lifecycle

Michelle Bennett — Mon, 14 Apr 2008 01:34:59 +0000

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.

Internet Reducing American Energy Use

Sarah Lozanova — Thu, 14 Feb 2008 15:47:41 +0000

The internet is saving 10 times the energy required to run an internet-linked computer.

Remember when renting a movie required a trip to the video store or checking a bank balance required a visit to the bank? Now, anything from used books to driving maps are just a click away. Telecommuting is common and taxes can be submitted electronically to the IRS. The internet is shaping our lifestyles, allowing us to save energy.

A recent study by the American Council for an Energy Efficient Economy (ACEEE) discovered that every kilowatt-hour of electricity used to power communications and information technologies is resulting in a 10 fold increase in energy savings.

“Acceleration of information and computer technology across the US landscape post 1995 is driving much of the nation’s energy-productivity gain,” says John Laitner of the ACEEE and coauthor of the study. “Had we continued at the historic rate of prior years, we would today be using the energy equivalent of 1 billion barrels of oil more [per year] than we were” in the early 1990s.

The Greening of Information Technology

jeffatdell — Tue, 11 Dec 2007 17:45:19 +0000

Infomration technology (IT) should have a minimal environmental impact. But many companies still sell computers, monitors and other IT equipment with lead, fire retardants and other harmful chemicals. There are, however, some companies that go way beyond simplly recycling cans and paper at the office. Let’s have a conversation about those companies like Dell and others that are making environmentalism a standard business practice.

Daily Tip: Use a Laptop to Save Energy

Jennifer Lance — Thu, 16 Aug 2007 14:59:50 +0000

If you are in the market for a new computer, an Energy Star-rated laptop is the most energy efficient choice. A laptop uses at least a fifth of the energy of a desktop computer. In addition, the smaller size of laptops means less packaging and more versability for your computer.

A typical laptop computer uses 15 watts of electricity, and it powers down often when not in use. A typical desktop uses 130 watts of electricity, including the monitor. In addition, a laptop is the perfect choice for individuals living off the grid. There have been many times when our power has been low or down, and my laptop’s battery has enabled me to keep working.

Don’t be fooled into thinking your computer’s screen saver saves energy. Unless the screen or backlight on a laptop actually turns off, a screen saver uses as much power as word processing. Also, don’t forget, you can save additional energy by adjusting your computer’s sleep mode to turn on more frequently.

Forget To Shutdown Your Computer? New App Helps You Remember

Michael dEstries — Fri, 16 Mar 2007 20:43:14 +0000

I saw a post recently while browsing Hugg promoting a new piece of software that might help those of us with “Forgetfulshutdowncomputer-itis”. Yes, it’s true. “Forgetfulshutdowncomputer-itis” is a real disease that effects 3 out of 5 Americans with a computer. Those without a computer did not respond to our emails about the survey.

Anyways, as I found while watching Grey’s Anatomy (that’s right, and I enjoy it.) “Forgetfulshutdowncomputer-itis” can be a significant cause of massive energy waste. The CO2 emissions caused by 15 computers consistently running are equal to the gas consumption energy-wise by one car! Overall, more than 30 billion watts of energy are lost to this terrible disease. Thankfully, there’s now a nice piece of software you can install to help optimize your computers energy efficiency.

Called Local Cooling, this little app will save power by either turning off your screen, putting your hard drive to sleep when not used or shutting down your PC when you are away. Of course, so you’re not interrupted in the middle of leaving a humorous response to this post, you can adjust when and how this happens in the settings. There’s also a little ‘incentive’ window that tells you how well you’re contributing in terms of trees or gallons of oil saved. Just glancing at it makes me feel all green inside…and hungry. Though I can’t explain the last part….

Anyways, download the app and give it a shot. At the very least, install it on your work computer and your co-workers computer. “Forgetfulshutdowncomputer-itis” may not go away tomorrow, but at least there’s a handy solution that’s got your back for those days that are worse than others.
