Energy conservation refers to the practice of reducing energy consumption through using less of an energy service. This can be achieved by using energy more efficiently or by reducing the amount of energy used for a given service. Simple actions like turning off lights when not in use or using energy-efficient appliances can significantly contribute to energy conservation efforts. By conserving energy, individuals and organizations can lower their energy bills, reduce greenhouse gas emissions, and help protect the environment. Implementing energy conservation measures not only benefits the planet but also promotes sustainable living and can lead to a more resilient energy future.
