(Notes)

  1. The sum total of numeral values given in the columns may not agree with figures given in the total column because fractions are rounded off.
  2. Figures for thermal power include geothermal power (until FY2009).
  3. Figures for new energy include wind power, solar power and geothermal power (after FY2010).
