The book "Energy Efficiency Policy of Major Household Electrical Appliances" provides a comprehensive analysis of energy efficiency policy for household appliances in the residential sector in Nigeria. It highlights the need for a well-formulated and implementable energy efficiency policy to reduce electricity consumption. By applying the Governance Assessment Tool (GAT), it examines what lessons can be learned from the governance system of energy efficiency policies and practices that focus on significant household appliances. The research spans the period from 2008 to the present and aims to map the status of implementation as well as the types of energy efficiency policies and practices. The book is aimed at researchers dealing with energy and environmental issues, energy efficiency in construction, as well as energy policy and governance.
