efficiency ratings

Efficiency ratings measure how well a device, system, or process uses energy or resources to perform its function. A higher efficiency rating indicates that more of the input (like fuel or electricity) is converted into useful work, with less wasted as heat or other losses. For example, an 80% efficient appliance uses 80% of the energy it consumes for its intended purpose, with the remaining 20% lost. These ratings help consumers and businesses compare options, identify energy-saving opportunities, and make informed choices that can reduce costs and environmental impact.
