I have been thinking about computers lately. It seems that turning them off is not really doing that much. Computers are still the device that probably uses the most energy out of every electronic device in my room. I am almost always on it watching videos, emailing, on facebook, playing games, and whatever else anyone does on the computer. I found a tip recently that should help people save more energy. Use desktops only when absolutely necessary. Laptops actually require less energy than desktops do. Using a laptop instead of a desktop cuts a whopping three quarters off of your energy usage. Not only that but when you are using the battery your are not using any electricity at all. Whenever I go to the library with my laptop I leave my charger in my room and can use my computer without any detrimental effect to the environment. This should be a relatively easy step for everyone in our group considering the fact that all of us have laptops. In fact the only time I ever use a desktop computer is for printing stuff out in the library. I write the paper on my laptop and once I am ready to print it I save it to a draft in an email. Then I quickly log on to a school computer in the library log in to my email find the draft and print my paper. At the most it takes only five minutes and for people who have printers need not even bother with this technique.
The cut down in power comes from what needs power. The laptop uses power for only itself the entire package requires one power source. For a desktop one at least needs to power the monitor as well as the tower (aka Pizza box aka big box that has the power button on it). Desktops also require a power source for speakers if the user wants to have sound. With a laptop it is also combined into one energy saving package.
As laptops become more compact and power efficient I encourage everyone who reads this blog to buy a laptop and you will be doing the environment a favor without ever knowing it. The more blogs I post and read on this topic cause me to think that the title of this blog is becoming more and more laughable. "It's not easy being green?" To the contrary with many of these tips it is.
