The table delineates how four different fuel types were used to produce electricity in five distinct Asian nations: Malaysia, Singapore, Thailand, South Korea, and Japan, in the year 2005.
Overall, there was a notable difference in the electricity preferences among these five countries, with Japan and South Korea using cleaner options like nuclear power and hydro and wind, while other countries relied more heavily on fossil fuels.
Regarding eco-friendly sources, nuclear was dominant in Japan and South Korea, contributing 49% and 33% of the national energy production, respectively. While this source was moderately used in Malaysia at 19% and Singapore at 13%, it was not available in Thailand. In terms of hydro and wind power, South Korea led with 48% of national energy production, nearly tripling the figure for Thailand, while remaining minimal at 5% or less in other countries.
As for fossil fuels, coal and lignite were predominant in Malaysia at over 60% and Singapore at 42%, while the remaining countries used considerably less of these sources, at no more than 6%. Petroleum products featured predominant only in Thailand at 36%, with negligible usage of 2-3% elsewhere. Other unnamed energy sources were most popular in Thailand at 42%, followed by Singapore and Japan, both at 39%. Meanwhile, those energy resources were not prevalent in Malaysia and South Korea, with just over 10%.
