Name one environmental consideration in engineering design.

Energy efficiency is a vital environmental consideration in engineering design because it directly impacts resource consumption and environmental sustainability. When designing a product or system, engineers strive to minimize energy usage during operation, which can lead to reductions in greenhouse gas emissions and lower reliance on non-renewable energy sources. This focus on energy efficiency not only helps preserve natural resources but also can contribute to cost savings for consumers and businesses over time. By incorporating energy-efficient practices and technologies, engineers can create designs that are both functional and environmentally responsible, addressing critical issues like climate change and resource depletion.

Other options, while important in their own context, do not specifically prioritize environmental concerns the way energy efficiency does. Durability of materials may enhance the lifespan of a product, but it doesn't inherently reduce environmental impact. The cost of production is primarily a financial consideration, and customer demand focuses on market preferences rather than ecological implications. Therefore, energy efficiency stands out as a key environmental consideration in engineering design.
