Study spanks Adobe Flash for abuses of power
Think green, block ads
We've known for years that graphics based on Adobe Flash and other third-party programming software can be clunky, time-consuming affairs that put our security at risk . Now comes new research suggesting they needlessly consume more power too.
Hansen stressed that the experiment can't be considered scientific because some of its methodology - which multiplied amperage by voltage - didn't adequately accommodate variances in the amperage over time. Still, by combining the Windows Task Manager with a tool called Kill A Watt , he said the study could be a launching pad for future scientific research by providing strong anecdotal evidence about the types of web browsing that tend to draw the most amperage.
The most useful conclusion: Use of the Firefox extensions NoScript  and Adblock Plus  is one of the most effective ways to decrease power consumption. When used to visit the 10 most power-hungry websites in Hansen's study, he saved .1 amp and more than 11 watts, the same needed to run a 40 watt compact fluorescent light.
While preliminary, the research suggests a direct relationship between websites that are power hogs and those that are potential security risks. So remember: Disabling Flash, Java, and Silverlight may not only be good for your security. It could also make your browsing greener. ®
