Manage your PC power plan.<\/strong> Most PCs have power management features that allow users to configure electricity consumption by device.\u00a0 Typically, users are allowed to choose settings for when the equipment is fully operational and actively being used, and for inactive periods. Depending on the manufacturer, a range of options are given, such as:<\/p>\n \n- power saving options when the PC is in active mode<\/li>\n
- turning off the monitor after a specified period of inactivity<\/li>\n
- turning off the CPU after a specified period of inactivity<\/li>\n
- activating sleep\/standby mode after a specified period inactivity.<\/li>\n<\/ul>\n
3. Limit the use of screensavers. <\/strong>Although screensavers are a way to personalise your PC, when they are triggered, they can keep the both the computer and monitor active. No power savings are realised. However, some might contend that having a screensaver shields the images on their computer screens from prying eyes. If this is a concern, the power saving settings of the PC should also be activated to eventually switch off the monitor (at the very least) if the PC remains idle for an extended period of time.<\/p>\n 4. Monitor consumption.<\/strong> There are a few software applications that claim to monitor and manage the power consumption of PCs, with the aim of realising significantly lower electricity bills. Most are targeted at enterprise network environments, such as GreenTrac<\/a>, Joulex<\/a> and NightWatchman<\/a>, but a few such as Granola<\/a> are designed for the individual PC.<\/p>\n There is also Welectricity<\/a>. Welectricity\u00a0a social network that provides a free online service that helps its members track and reduce their electricity consumption at home. Welectricity was developed in St. Vincent and the Grenadines<\/a>, in the Caribbean,\u00a0and is currently being used in 78 countries around the world.<\/p>\n 5. Use greener equipment\/devices.<\/strong> As reflected in the above Table, there is direct relationship between the equipment used and power consumed. For example laptops are considerably more efficient than desktop computer systems. However, laptops tend to be more expensive than desktops and generally, they need to be replaced more often than desktops, which can be more easily upgraded or have parts replaced. Further, greater care and consideration is needed when selecting laptops, as the environmental impact of their manufacture and disposal should be factored in. For guidance on the most environmentally friendly laptops, see the Guide to Greener Electronics<\/a><\/em><\/strong>.<\/p>\n Additionally, it is increasingly possible to purchase more energy efficient computing equipment. The most widely recognised standard is Energy Star<\/a><\/em>, which is an international standard used for energy-efficient consumer products. There is usually no appreciable difference in price for Energy Star<\/em>-compliant products when compared with other non-compliant devices. It is therefore strongly recommended that energy efficient options be considered.<\/p>\n How do you plan to reduce your computing carbon footprint?
