Energy efficiency

Definition

Energy efficiency refers to the practice of using less energy to provide the same level of service or output. It plays a crucial role in reducing energy consumption and greenhouse gas emissions, which in turn helps to mitigate climate change and lower energy costs. By improving energy efficiency, technologies can be optimized to use energy more effectively, whether it's through smart grid systems that enhance energy distribution and management, or through green building technologies that minimize energy use in construction and operation.
