In 2023, the total number of researchers in the electricity, gas, steam, air conditioning, and water supply sectors in Japan was 1.22 thousand (FTE). The forecasted data shows a steady decline to 1.02 thousand by 2028. This represents a year-on-year decline of approximately 3.39% between 2024 and 2025, followed consistently in subsequent years with similar trends. The compound annual growth rate (CAGR) over this five-year period is negative, indicating an average decrease in researcher numbers each year.
Future trends to watch for include technological advancements and innovations that may drive growth in efficient energy use and management. Policy shifts towards sustainability and green energy could also impact researcher demand, potentially stabilizing or reversing current trends.
