The table illustrates the percentage distribution of five different fuel types used for electricity generation across five Asian nations in 2005. Overall, it is evident that energy dependency varied significantly between the countries, with coal and lignite dominating in Malaysia and Singapore, whereas nuclear and hydro/wind power played more substantial roles in Japan and South Korea.
Malaysia recorded the highest reliance on coal and lignite at 61%, followed by Singapore at 42%. In contrast, Thailand, South Korea, and Japan utilised these fuels minimally, at 3%, 5%, and 6% respectively. Thailand stood out for its significant use of petroleum products, accounting for 36% of its energy mix, which was substantially higher than the other four nations, where this figure remained between 2% and 3%.
Regarding cleaner energy, Japan led in nuclear power usage at 49%, followed by South Korea at 33%. Conversely, Thailand reported no nuclear energy production. South Korea showed a strong preference for hydro and wind power at 48%, whereas this source contributed only 3% to 5% in the other countries. Finally, 'other' sources were most prominent in Thailand and Singapore, both at 39% to 42%, compared to lower figures in Malaysia and South Korea.
