			<content:encoded><![CDATA[<p>User interface specialists and aesthetes may love Mac chic, but coolness comes at a hot cost: increased power consumption. Before the Mac OS X made hipsters salivate over 3D effects, a typical home or business computer user was well satisfied with plain 2D graphics. Your typical word processor and spreadsheet, after all, is a 2D affair.</p>
<p>Inevitably, Microsoft followed Apple down the 3D maze. The beneficiaries would not just be Microsoft itself, trying to stay cool and relevant, but hardware manufacturers who would make a killing selling businesses and consumers &#8220;upgrades&#8221; to Vista-capable machines.</p>
<p>As it turns out these business benefits were <a href="http://www.nytimes.com/2008/03/09/business/09digi.html">illusory</a>. Even worse, they will also suck enormous amounts of unneeded electricity off our overtaxed grid to power almost entirely unnecessary 3D graphics cards, purchased to bring computers up to &#8220;Vista capable&#8221; (or, more accurately, &#8220;Vista Premium capable&#8221;).</p>
<p>Moore&#8217;s Law gives us increasingly powerful chips, but rather than do more with less, we find new ways to do (very marginally more) with more. It&#8217;s a sick parallel to the automotive world, where <a href="http://articles.moneycentral.msn.com/SavingandDebt/SaveonaCar/TheCostlySecretsOfHybridCars.aspx">hybrid vehicle technology gives cars more power</a> with little or no mileage improvements. But as we&#8217;ve seen with SUVs, there&#8217;s little to stop rising consumption until a combination of high costs and cultural backlash take the edge off demand. Corporate purchasing officers wield vast power to stop this ecological calamity: may they find it in their economic and moral interests to do so.</p>

			<content:encoded><![CDATA[<p>Sunday&#8217;s <a href="http://www.doonesbury.com/strip/dailydose/index.html?uc_full_date=20070506">Doonesbury</a> touched on one of my major ecological concerns: standby power and the LED lights that give them away. Trudeau is usually either earnest or obviously sarcastic in  his strips, but this one&#8217;s hard to read. The (increasingly-mannish) Alex observes to her roommate, &#8220;Isn&#8217;t it thrilling? A roomful of technology in standby mode, ready to leap to life and serve us!&#8221;</p>
<p>There seems to be <a href="http://www.timesonline.co.uk/tol/comment/columnists/matthew_parris/article691025.ece">much debate</a> over <a href="http://www.economist.com/displaystory.cfm?story_id=5571582">how much power devices in &#8220;standby&#8221; consume</a> (also known as &#8220;<a href="http://en.wikipedia.org/wiki/Standby_power">vampire power</a>&#8220;), there&#8217;s no question that our modern technologies are not costless. Those LEDs are twinkling reminders: &#8220;turn me off!&#8221;</p>

<p style="font-size:smaller; font-family:serif">These ghosts present a true menace.</p>
<p>I took the above picture from outside a certain office last Friday. I saw three CRT monitors burning away energy, unproductively, for an entire weekend. <a href="http://www.time.com/time/specials/2007/environment/article/0,28804,1602354_1603074_1603535,00.html">Using a &#8220;screensaver&#8221; is no solution</a>. Please, set your computers to <i>turn off</i> your monitors after 10-15 minutes, and <i>shut down</i> your computer when you&#8217;re not using it!</p>
