But ultimately, here are the top five ways to make a difference.
When not in use, turn off the juice
Yup, the easiest way to save energy is to simply turn your computer off when it’s not being used, and the savings from doing so can be substantial. According to ComputersOff.ORG, simply turning your computer off at night or when it’s not being used can save as much energy as it takes:
- to run a clock radio for 1,392 weeks
- to make 9,280 bags of microwave popcorn
- to wash 464 loads of washing
- to use your blow dryer for 5,568 hours
- to vacuum for 464 hours
- to produce 3,480 plastic bags
- to run your microwave 24 hours a day for a week
- to boil your kettle for 24 hours a day for 268 days
It’s worth noting that in recent years it’s possible to buy a very green desktop energy efficient computer, if you have a newer system and use it with the power management features enabled (see below), your savings will probably be smaller. But every little helps, right?
Before moving on, let’s dispel a frequently heard myth: namely that turning your computer on and off regularly will cause it to wear out more quickly. This is not the case. Today’s computers are designed to last through in excess of 40,000 on/off cycles and, even if you turn your computer on and off several times a day, it’s unlikely that you’ll reach anywhere close to that number of cycles before your computer is retired.
Use power management
If you really can’t bear to completely switch off, then using power management options to put your computer into an energy-saving sleep mode when it’s not being used is the next best thing and will save almost as much electricity. When operating normally, a computer and LCD monitor will use between 100 and 300 watts of electricity – but this reduces to only 1 to 6 watts in sleep mode. Climate Savers Computing provide some recommended power management settings and instructions on how to configure those settings.
Extend the life of your current computer
If every computer was to remain in use for, say, an extra 12 months, then substantially fewer computers would need to be produced and substantially fewer resources would be used in manufacturing, packaging and shipping. Consequently, the longer you can delay the retirement of your computer, the better it is for the environment. There are a couple of ways you can do this, this first and easiest of which is to simply keep on using your current computer for longer. Add some RAM, a bigger hard disk or a better graphics card – get as much mileage out of your computer as you can before replacing it.
The second way to prolong the life of your computer is to make sure that it’s reused rather than scrapped. While it may not have enough horsepower to enable you to play to latest games, your old computer would almost certainly be appreciated by somebody who only wants to browse the web and email. So, sell it, or give it to a needy friend or relative, or use Google to find a local donation scheme – just don’t put it out with the garbage! Hint: before parting with your old computer, be sure to wipe the data (How To Completely & Securely Erase Your Hard Drive).
It takes resources to manufacture ink, ink cartridges and paper, so it makes sense to think about what and when you print.
There are a number of ways that you can print smarter:
- Don’t print! Think before you print and only print what really needs to be printed. Do you really need a hard copy of that forwarded email joke? Reducing the amount that you print will save energy, ink, paper and may even help extend the life of your printer.
- Print on both sides of the paper. This can cut your paper consumption by as much as 50% and, as an added bonus, you’ll use also less energy too when printing double-sided (according to the U.S. Department of Energy, the saving in energy costs may amount to as much as $170 during the life of the printer). If you need to print a substantial amount on a regular basis, consider buying a printer that supports automatic double-sided printing as this will avoid the need for manual-feeding (which is fine if you only print something once in a while, but not so fine if you print multiple times per day).
- Cut out waste. Blank pages and unnecessary text in print jobs can result in a substantial amount of wasted ink and paper. A solution such as GreenPrint will enable you to print only what needs to be printed – blank pages and unnecessary text such as web addresses are automatically eliminated – reducing the amount of ink and paper that you’ll use. GreenPrint comes in free and paid versions.
Buy an ENERGY STAR rated computer
“If all computers sold in the United States meet the ENERGY STAR requirements, the savings in energy costs will grow to more than $2 billion each year and greenhouse gas emissions will be reduced by the equivalent of greenhouse gas emissions from nearly 3 million vehicles.” So says ENERGY STAR – a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy that labels products that meet a minimum set of energy-efficiency standards. Choosing a computer that has the ENERGY STAR label and using it with the recommended power management settings will enable you to keep electricity use to a minimum.
So, being green really is quite easy. And the best part about it is that you’ll not only be doing your bit to help the environment, you’ll also be keeping your electricity bill down – and saving money is something we all like to do, right?
