As concern for carbon emissions grows, most countries have introduced legislation to regulate the efficiency of external power supplies (EPS), so that as little as possible of our natural resource is wasted. This legislation encourages power supply manufacturers to introduce EPS models with higher efficiency and lower no-load power consumption and, by gradually tightening the limits on these figures, governments and regulatory bodies around the world are effectively driving the power supply industry to produce more energy efficient products.
