What does energy efficiency refer to?

Energy efficiency refers to the ability to provide the same service or output while using less energy. This concept emphasizes minimizing energy waste by using technology or approaches that require less power to achieve the same results. For instance, energy-efficient appliances use advanced technology to carry out tasks such as heating or cooling with less energy compared to older models.

This principle is crucial in addressing climate change and reducing overall energy consumption, as it helps lower greenhouse gas emissions while still meeting energy needs. Improved energy efficiency not only benefits the environment but can also lead to significant cost savings for consumers and businesses by reducing energy bills.
