Sony has warned the Japanese government it may have to shift manufacturing out of the country as it tries to meet the green energy promises of customers such as Apple, according to a minister.

Sony’s concerns were echoed by the chief executives of Ricoh, the electronics company, cosmetics business Kao and fund manager Nissay Asset Management during a meeting with Taro Kono, Japan’s minister for administrative reform, earlier this month. “They told me it’s very difficult for them to purchase renewable energy in Japan. The quantity is limited and the price is very high,”
