Distributed Energy Resources (DER) refer to small-scale energy generation or storage systems that are located close to where the energy is used. Examples include solar panels, wind turbines, and battery storage systems. These resources can operate independently or in conjunction with the larger electricity grid, providing flexibility and resilience to energy supply. DER can help reduce energy costs, lower greenhouse gas emissions, and enhance energy security. By utilizing local resources, such as solar energy or biomass, communities can become more self-sufficient and less reliant on centralized power plants. This shift supports a more sustainable and efficient energy system.
