Ah, I love the good old college days. You know, the couple weeks you get antsy before you go back to college, or the lucky freshmen who have no idea about the great journey they’re going to embark on (mainly because freshman parking is the furthest point on campus). Many schools across the country are participating in green initiatives (See our post on Cool Green Campuses) but buying a new computer is a chance for you to take the green initiative into your own hands!
As we all know, laptops use significantly less energy than desktop computers. On the high end, a laptop might use about 45 watts, compared to a desktop which uses about 200. That’s 155 watts in difference! If the 15,000 students at your school all had laptops versus desktops and they were all running at the same time, there would be 2,325,000 watts, or 2.325 Mega-watts in difference. That’s about the amount of power a wind turbine outputs!
When you’re out purchasing a computer, we encourage you to get an ENERGY STAR® qualified product. They use less energy and the units must meet specific efficiency criteria.
Lastly, check out the Energy Star Computer Power Management Savings Calculator. You can plug in some stats about your computer (watts it uses), your energy usage patterns, and settings (sleep settings) and the calculator will produce some interesting savings results.
Have fun this school year!

That is a perfect example of what conservation of energy can do. Imagine if everyone switch to geothermal heating and cooling.
It would seem to me that "cloud computing" doesn't get enough play in the "energy reduction" community. In the Laptop VS PC arena, with the college community it would make more sense to have something like a "dumb terminal" that is hooked up to the university servers and the internet. There could be USB port for flash drives and portable hard drives, etc., and that would cut down on a lot(!) of energy usage as well as wasted computer manufacturing capacity. After all, there is a wholesale migration from PC's to tablets and hand held devices. Think about that!
