Energy-inefficient

Describes a device, system, process, or building that consumes a significant amount of energy relative to the amount of useful work it performs or the results it achieves. This can manifest in high electricity consumption, excessive fuel usage, or substantial heat loss. energy-inefficient systems often represent economic waste, contributing to higher operating costs and environmental concerns like increased greenhouse gas emissions. Identifying and mitigating energy inefficiencies is a crucial step towards sustainability and resource conservation. These inefficiencies can stem from various factors, including outdated technology, poor design, lack of insulation, or inefficient operational practices.

Energy-inefficient meaning with examples

• The older model refrigerator was notoriously energy-inefficient, requiring significantly more electricity than modern appliances to keep food cold. Its antiquated compressor and poor insulation led to substantial energy waste, noticeably increasing our monthly electricity bill and contributing to our carbon footprint. Upgrading would bring benefits.
• An aging furnace, particularly one lacking proper insulation, proves energy-inefficient during winter. Heat escapes through uninsulated ducts and walls, forcing the furnace to work harder and consume more fuel to maintain a comfortable temperature in the home. This also adds to the overall cost.
• The construction of the building showed energy-inefficient design, with single-pane windows and minimal insulation, making it challenging to regulate temperature. This leads to an imbalance of air pressure, leading to excessive energy use. The use of alternative measures, such as triple glazed windows, would be extremely beneficial.
• The older car models are largely energy-inefficient when compared to hybrids and electric vehicles because of the lack of technological advances. The combustion engine, though efficient to its design, is a large contributor to air pollution. A new fuel type could be a real improvement in these cases.
• The company implemented an energy-inefficient production process, with excessive lighting and equipment in a poorly insulated warehouse, which consumed a considerable amount of electricity. Upgrading to newer equipment or alternative processes could significantly lower operating costs and reduce its environmental impact.
