Energy efficiency is the practice of using less energy to provide the same amount of useful output from a service (such as heating water, lighting, or cooling a fridge).

Energy efficiency is providing the same or better service using less energy. Energy services are all the benefits we derive from energy use, such as illumination, thermal comfort, cooking, transport of people and freight, and many industrial and agricultural functions.

Efficient energy use, or energy efficiency, is the process of reducing the amount of energy required to provide products and services. There are many technologies and methods available that are more energy efficient than conventional systems.

Energy efficiency is called the “first fuel” in clean energy transitions, as it provides some of the quickest and most cost-effective CO2 mitigation options while lowering energy bills and strengthening energy security.

Energy efficiency is one of the easiest ways to eliminate energy waste and lower energy costs. It is also one of the most cost-effective ways to reduce air pollution, help families meet their budgets, and help businesses improve their bottom lines.

North Carolina residents can take advantage of a wide variety of strategies and programs to increase energy efficiency and save money on electricity bills. Check below for tips and resources to help keep your energy costs low.

2024年1月12日 · Efficiency and conservation measures can help to directly lower consumers' energy bills and potentially reduce greenhouse gas emissions associated with energy use. Consumers also benefit indirectly when reducing their electricity consumption helps to reduce demand on the electric system.

ENERGY STAR® is the simple choice for energy efficiency. For more than 20 years, EPA’s ENERGY STAR program has been America’s resource for saving energy and protecting the environment.

Of the $2,000 the average American spends paying for energy annually, $200 to $400 could be going to waste from drafts, air leaks around openings, and outdated heating and cooling systems. By reducing these losses through energy efficiency upgrades, you can save money and be more comfortable in your home or business. Start with an Energy Evaluation

Energy efficiency measures the energy service delivered (output) compared to the energy used (input). A more efficient product provides the same service with less energy.
