The drive for better energy efficiency has become essential for both home and professional computing. A computer that uses less power produces less heat, can potentially last longer and, of course, is more eco-friendly. To achieve this efficiency, you need to act on three fronts: the <\/span>initial choice of hardware<\/b>, the <\/span>fine-tuning of software settings<\/b>, and the <\/span>adoption of everyday habits<\/b>.<\/span><\/p>\n

Find out how to turn your device into an energy-saving champion, from choosing components right through to switching it off.<\/span><\/p>\n

1. Choosing hardware designed for energy performance<\/span><\/h2>\n

The point of purchase is your first opportunity to limit your future PC\u2019s power demands.<\/span><\/p>\n

    \n
  • The design of laptops makes them <\/span>inherently less power-hungry<\/b> than traditional desktop towers, because they are optimised for battery life.<\/span><\/li>\n
  • For light use only (web browsing, email), investing in a <\/span>mini PC<\/b> or a <\/span>small form factor PC<\/b> is the best way to achieve minimal power consumption.<\/span><\/li>\n
  • <\/span>Modern components<\/b> such as SSDs (which have no moving parts) and processor chips labelled as low power are major advantages that <\/span>reduce the electricity required<\/b> for the same level of performance.<\/span><\/li>\n<\/ul>\n

    2. Setting up the operating system for efficiency<\/span><\/h2>\n

    The operating system orchestrates power consumption and offers several ways to control it.<\/span><\/p>\n

      \n
    • Switch to \u00ab\u00a0power saving\u00a0\u00bb mode:<\/b> It\u2019s essential to use your OS\u2019s power saving mode. This mode <\/span>limits the maximum power<\/b> of the <\/span>CPU<\/span><\/i> and <\/span>GPU<\/span><\/i>, saving energy without affecting basic tasks.<\/span><\/li>\n
    • Set sleep timeouts:<\/b> To prevent the screen and machine staying on unnecessarily, configure a <\/span>short sleep delay<\/b> (a few minutes) after a period of inactivity.<\/span><\/li>\n
    • Adjust brightness:<\/b> The screen often uses the largest share of power. <\/span>Turning down the brightness<\/b> to the lowest comfortable level is one of the most effective actions you can take.<\/span><\/li>\n
    • Control running processes:<\/b> Close any windows and applications<\/b> running in the background that you\u2019re not using. Less work for the processor means less energy consumed.<\/span><\/li>\n<\/ul>\n
