Enter your console's active and standby wattage and usage pattern to see the real annual cost, standby included.
Instant-on/standby mode can account for more than half a console's annual energy use if left on 22 hours a day — switching to full power-off when not playing meaningfully cuts this.
Modern consoles left in "instant-on" or rest mode draw continuous standby power for the roughly 22 hours a day most people aren't actively playing, which can add up to more annual energy than the actual gaming sessions themselves. Fully powering off when not in use — sacrificing instant wake for real savings — is the simplest way to cut this, similar in principle to the phantom load from other always-on electronics.
Yes, often meaningfully — since standby runs 20+ hours a day versus a few hours of active play, reducing standby draw to near-zero by fully powering off can cut a console's total annual energy use substantially.
No — it varies by model and generation, with newer consoles generally improving standby efficiency, so checking your specific console's published power specs gives a more accurate number than a generic assumption.
