Question
Name the four tests for responsible electronics.
Answer
Safe in use and in failure; energy-efficient for the job; low standby power; and repairable or recoverable at end of life.
Question
Give three ways an electronic product reduces its energy use.
Answer
A switched-mode supply instead of a linear one, LEDs instead of filament lamps, and a processor that sleeps between events with a sensor waking it only when needed.
Question
Why does half a watt of standby power matter?
Answer
Because it is drawn every hour of every year in billions of devices. It is capped across the EU at 0.5 W per device precisely because the per-product figure is small and the total is not.
Question
How can adding electronics make a durable product less sustainable?
Answer
By shortening its life. A control board lasts a fraction of the mechanical parts, is rarely repairable and is not stocked for long, so a working machine is scrapped for a cheap part.
