Energy-efficient technologies

Abstract

Nowadays, research, development, deployment, and investment in energy-efficient technologies take place in many areas including lighting, household appliances, building envelope, windows, doors, heating, ventilation, air-conditioning, heat exchangers, working fluids, geothermal heat pumps, water heating, sensors and controls designed to measure building performance, smart grids, industrial process, electrical motors, and energy-efficient transport. This chapter briefly introduces some technologies that are related to these areas including energy-efficient lighting, refrigerators, electrical motors, and vehicles. It also presents policies to facilitate investments in several most common energy-efficient technologies and provides economic and technical guidance on choosing and investing in energy-efficient technologies.
