PCSTATS Pits Google Versus Blackle in a Contest of Efficiency
You are undoubtedly reading this on a computer; either a desktop or a laptop. If not one of those machines, a smaller device with a screen: a smartphone or a tablet. Whatever your chosen method of browsing the Internet, it has a screen, a battery, and if you have a portable device a charger that plugs into a wall outlet.
What is your standard search engine? It has to be Google because they are known for their interactive and eye-catching logo changes on holidays and notable days like an artist’s birthday or like today’s- a celebration of the zipper!. But what if you found a more efficient search engine and it had nothing to do with how quickly results were aggregated? This search engine was sure to suck less power because it used a black background rather than a white background. Would you switch?
Blackle has been around for a long time; it was launched in January of 2007 by Heap Media, and ever since its inception the claim that the site saves energy by using less monitor wattage has been in dispute. At the beginning of the month PCSTATS decided to compare Blackle to other sites and see if this was a case of greenwashing or if the site really was energy-efficient.
They used two different monitors hooked up to a Extech power analyzer: an older 19" CRT ADI Microscan E66 (the CRT stands for cathode ray tube) and a newer flat panel 19" LCD Samsung 192MP. Their starting point was the energy usage for a white screen and black screen. Then they took a step further and looked at power used by 57 websites, including their own, across 7 categories.
They looked at extremely popular websites like Facebook, Apple,YouTube, and CNN. Actual searches were performed on retail sites like Amazon where they “shopped” for a computer and Etsy where they browsed for t-shirts (hopefully ones with punny messages) and they even tested sustainable design sites, for well, sustainability.
Some of their findings weren’t surprising: LCD monitors in general are more efficient and Flash or “other moving bits” use more power.
PCSTATS says: “Blackle’s claims appear to hold water, although the difference is just 17.7W and 3.8W for CRT and LCD respectively. What that adds up to over the course of a year, for every second you spend doing a search on Google is anyone's guess.”
So if you have an older monitor you might want to consider a switch to Blackle and if you have an LCD you can carry on as you see fit. Though Blackle would appreciate it you started using their site as a small act of change that they believe could lead to greater acts of environmentalism.
1944: Camano Class Light Cargo Ship was laid down for the US Army as FS-289 at Wheeler Shipbuilding in Whitestone, NY.
1955 - 1963: Used as a cargo supply ship for the Texas Towers, a network of advanced radar stations located off the Eastern Seaboard. In 1957, Capt. Sixto Mangual was commander of the AKL-17 and in 1961 it was rechristened the USNS New Bedford. The New Bedford, sailing out of State Pier, was keeping vigil when Texas Tower No. 4 callapsed off the New Jersey coast during a January 1961 nor'easter.
2006: Design of the Tesla Turbine began on June 11, 2006. The Sea Bird was sold by Defense Reutilization and Marketing Service for commercial service.
