What Is Energy Efficiency?

Energy efficiency means smarter energy use. Energy efficiency is about using better technology and practices to use less energy to accomplish the same tasks, while continuing to keep homes and businesses comfortable.

While energy efficiency encompasses all aspects of energy conservation from power generation facilities to the transmission and distribution process to the end user, Energy Efficiency Business Coalition (EEBC) focuses on this last stage. End-user energy efficiency (or demand side management) is the act of reducing consumption of electricity and gas through building improvements, mechanical and electric system upgrades, consumption and behavior education, as well as smart billing methods.

Energy efficiency speaks to how much energy is actually being used as intended. Energy efficiency means doing the most with a limited amount of energy and wasting the least in the process. EEBC and its members focus on the energy efficiency in this final end-user stage in the built environment.

Energy efficiency also includes demand side management, demand response, and smart grid solutions. At times, emerging technologies including building automation, electric vehicle charging, and customer engagement encourage or facilitate the adoption of energy efficiency solutions.

Energy Efficiency Examples

  • An LED light bulb uses at least 75% less energy, and can last up to 25 times longer, than incandescent lighting.
  • An energy-efficient washing machine washes the same amount of laundry using 35% less water
    and 20% less energy than standard washers
  • A well-sealed and insulated house leaks less heat in the winter, and less chilled air in the summer, and
    therefore requires less energy to stay comfortable.

  • A factory with a smart energy-efficiency plan can reduce energy waste through simple practices like shutting
    down their ventilation system during non-production hours.
