What does efficiency do?

Efficiency does several important things, it reduces waste, saves money, saves time, saves energy, and improves performance and sustainability. When a system is efficient, it converts a higher percentage of input into useful output and loses less as waste heat, friction, or unnecessary effort. In a home, efficiency does the job of keeping you comfortable while using less electricity and gas, which lowers utility bills by 15 to 30 percent and reduces pollution. In a business, efficiency does the job of allowing more products or services to be delivered with the same staff and resources, increasing profitability and competitiveness. In personal life, efficiency does the job of freeing up time for more important activities by eliminating unnecessary steps and organizing tasks better. In the environment, efficiency does the job of conserving natural resources and reducing emissions because less fuel is needed for the same outcome. For example, an efficient car does the same travel with less gasoline, an efficient light bulb does the same lighting with less electricity. Overall, efficiency does the critical function of maximizing value from limited resources, which benefits individuals, economies, and the planet.
