The aim of the study was to determine the association between parental attitudes and saving energy in the perception of young people with autism spectrum (13–17 years old). The character of studies was pilot. The diagnostic survey method was used, along with The Scale of Parental Attitudes by M. Plopa and an authored survey questionnaire. Deliberate random sampling was applied. Statistical analysis showed that an attitude towards autonomy manifested by mothers, as well as an attitude of acceptance in mothers and fathers, turned out to be significant in adolescents with ASD showing a positive attitude towards energy saving, and these correlations were positive, strong and statistically significant. An overly protective attitude of mothers turned out to be significant in shaping a negative attitude towards energy saving among adolescents with ASD with a significant, positive moderate correlation. Regression analysis showed that the perception of the father’s parental attitude as accepting was a statistically significant predictor of a positive attitude towards energy saving, and that the perception of the mother’s parental attitude as demanding and overly protective was a statistically significant predictor of a negative attitude to energy saving. The achieved results acquire an additional aspect, i.e., a financial dimension in the household budget.
