Energy efficiency refers to the use of technologies and production systems that utilizes less energy to perform tasks. In other words, energy efficiency entails using the available power optimally and reducing the wastage of energy (Solmes, 2009). For example, the use of energy-saving bulbs that uses less energy to generate light that is equal to that produced by the incandescent bulb consumes more power. Energy efficiency is critical because it supports the sustainable production and use of energy (McLean-Conner, 2009). For instance, using roof insulation materials that conserve power would help to reduce the amount of heat energy required to heat buildings in the long run. The term energy efficiency has substantial effects on living things and the physical world. First, energy efficiency improves access to living things, including humans, to energy. Improving access to sufficient energy ensures that human beings have better access to health care, education, and other social amenities. This is because the provision of necessary social facilities such as education and health care requires a sustainable supply of energy (Martinez & Ben, 2018). In terms of the physical world, energy efficiency supports the conservation of natural resources in the physical world (Sioshansi, 2013). Practically, energy efficiency enables schools, healthcare facilities, hotels, and other institutions to prepare more food, generate more light, and produce more heat using less energy. Regarding the promotion of energy efficiency, embracing technologies such as energy-saving bulbs is one way that can be utilized. The use of energy-saving technologies would reduce the exploitation of both renewable and non-renewable sources of energy, thus supporting sustainable energy use (Rajan, 2003). In addition to that, using renewable energy sources such as wind power would help in supporting sustainable consumption and production of energy. Such sources would reduce environmental pollution and make energy use more sustainable.
