THE traditional wood fire in rural China is gradually being replaced by one fuelled by cleaner, greener marsh gas as by the end of 2001, over 10 million rural households nationwide were using marsh gas and some 400 counties were developing their marsh gas energy resources.
In south-west China's Yunnan Province, for instance, the number of rural households using marsh gas reached 800,000 by the end of last year, including 180,000 which converted to the new fuel under a provincial government programme.
