In recent years, there has been a significant change in conditions relating to electricity and energy. Increasing the efficiency of electricity usage and utilizing renewable energy sources are important issues being addressed by society. Sony has promoted the research and development of such environmental technologies as energy conservation, storage and generation since before this situation came about. In 2011, Sony launched energy storage module IJ1001M and also energy storage batteries for commercial and residential use, which can be used for load leveling during peak electricity periods.
Sony is also currently pursuing research and development of next-generation energy technology, including bio batteries, as well as "authentication outlets" and home energy management systems (HEMS), which aim to help build a new relationship between people and the electricity they use.
