READ MOREJapan has been a leading country in the area of energy efficiency. Since the 1970s when the oil crisis hit, Japan, which depends almost wholly on imported energy supplies from abroad, has been conducting various efforts on energy conservation and diversification of energy sources.
READ MOREStrong consumer spending on new fuel-efficient and electric cars is expected to help overall energy efficiency-related investment rise by 16% in 2022, to just over USD 560 billion. Under currently stated policies, this figure is set to increase a further 50% to almost USD 840 billion per year from 2026 to 2030.
READ MOREJapan has strengthened its efforts to improve energy efficiency. To further enhance energy consumption efficiency, a target reduction amount for 2030 has been expanded to 62 million kl crude oil
READ MORETypical energy costs for wind power would be ¥4–7/kWh as opposed to ¥16–40 kWh for rooftop solar PV. In comparison METI''s estimate for nuclear power is ¥4.8–6.2/kWh, although Iida (Japan Times, 2007) asserts that the real figure, once a number of omitted costs have been included, is more often above ¥10/kWh.

READ MOREThis reflects Japan''s long history of rigorous efficiency policies. Oil savings in Japan were equivalent to more than 20% of its oil imports in 2016 and significantly improved the country''s energy security. More generally, between 2011 and 2018, Japan''s total final energy consumption decreased by 8%, while GDP increased by 8%, resulting
