Which of the following is a method to conserve energy in daily life?

Recycling materials is an effective method to conserve energy in daily life because it reduces the need to extract, process, and transport raw materials, which is an energy-intensive process. When materials such as paper, plastic, glass, and metals are recycled, the energy required to create new products from these recycled materials is significantly lower compared to manufacturing them from virgin resources. For example, recycling aluminum saves about 95% of the energy needed to produce new aluminum from bauxite ore. This energy conservation not only helps to preserve natural resources but also reduces greenhouse gas emissions associated with production processes.

In contrast, using incandescent light bulbs consumes more energy compared to energy-efficient options like LED bulbs, which can waste a significant amount of energy in the form of heat. Leaving electronics on standby continues to draw power, contributing to energy waste rather than conservation. Taking longer showers can result in higher energy use as it typically increases the energy needed for heating water. Thus, recycling stands out as a proactive approach to conserving energy and promoting sustainability.
