Energy Efficiency covers wide-ranging topics related to end-use energy efficiency, energy savings, energy consumption, energy sufficiency, and energy transition towards climate neutrality in all sectors across the globe. Coverage includes energy efficiency policies at all levels of governance enabling social, organizational, and economic factors of sufficient and efficient behavior and decisions; analysis and modeling of energy efficiency performance, measures, policies, outcomes, and impacts; energy management systems and energy services; the role of energy efficiency and demand-side management in energy planning, energy markets and risk assessment; local sustainable energy planning; energy behavior; acceptability of policy, technology, and new energy systems; and emerging technologies and approaches to improve energy efficiency. Energy Efficiency editors welcome new and original work that contributes to our knowledge of energy efficiency and energy savings and that offers broad implications for energy efficiency within the transition to a more sustainable energy system and climate neutrality. Editors will only consider clearly written, broadly applicable and accessible submissions that contain novel elements, issues, approaches, methods or results and that inspire progress in actual energy efficiency gains and energy savings. Areas of current interest include: Evaluation and modeling of energy efficiency policies and demand-side management programs Impact of energy efficiency economy-wide across diverse levels of governance Contribution of energy efficiency to climate change mitigation goals Co-benefits or multiple benefits of energy efficiency and energy savings, especially health benefits and productivity Policies and incentives for energy efficiency and demand-side management programs in future electricity markets with high shares of renewables and prosumers Innovative approaches to improving energy use by applying new business models and latest advances in digital information and communications technology Effects of behavioral approaches and social practices to energy demand and efficiency Corporate energy efficiency and energy savings management programs, investment decisions, financing; energy efficiency and energy savings as corporate social responsibility Energy efficiency in transport, buildings and communities showing the benefits of an integrated approach. The role of energy flexibility and demand-side response in the energy transition Case st
