     The purposes of this research were to study 1) level of knowledge and attitude regarding the participative energy conservation of chemical industrial workers
and 2) Relationship between level of knowledge and attitude regarding the participative energy conservation of chemical industrial workers. The sample was 162 workers in a chemical company at Wellgrow Industrial Estate in Chachoengsao province. The research instruments was questionnaires which consisted of knowledge and attitude tests with reliability at the 0.88 level.The data was analyzed by computer program. The statistics that used were frequency, percentage, mean ( ), standard deviation (S.D.) t-test, one-way (anova), Least-Significant Different (LSD) for comparisons and Pearson correlation. The results were :
	1. the level of knowledge regarded to participative energy conservation of workers was at medium level. And the level of attitude on participative energy conservation of workers was at good level.
	2. the comparison of knowledge regarded to participative energy conservation of workers on 6 factors was found that workers in different group of sex did not have any statistically significant difference in their knowledge regarded to participative energy conservation. But the workers in different group of age, level of education, working period, department and position had statistically significant difference at the .05 level.
	3. the comparison of attitude on participative energy conservation of workers on 6 factors was found that workers who were different in working period and department did not have any statistically significant difference in their attitude on participative energy conservation. But the workers in different group of sex, age, level of education and position had statistically significant difference at the .05 level.
	4. the relationship between knowledge and attitude of participative energy conservation of chemical industrial workers showed statistically significant correlation.
