Energy efficiency

Definition

Energy efficiency refers to the practice of using less energy to provide the same level of service or output. By maximizing energy efficiency, we can reduce energy waste and lower overall consumption, which is crucial for sustainable development and reducing greenhouse gas emissions. This concept is tightly linked with renewable energy technologies and policies as they often aim to create systems that optimize energy use while relying on cleaner energy sources.
