Background. The major challenges that prevent the wide-scale adoption of emerging personal clean energy production are unawareness and low self-confidence. We tested a hypothesis that a combination of a new technology and educational methods could lead to the increase in awareness of children to clean energy possibilities and to an increase in self-confidence in applying them. Methods. Here we report on a toolkit that combines low carbon, clean energy source, Zn/Cu/potato batteries, sufficient to power light-emitting diodes, with a non-formal education by experience program, based on case studies and hands-on experience with battery assembly for 6-11 years old children, led by trained 12-14 old youth leaders. Results. The results show that the education experience increased the awareness of the children to produce electricity at home from unconventional, yet available raw materials and their self-confidence in being able to do this (p=0.008). Conclusions. The developed toolkit supports environmental and energy literacy education through non-formal training, increasing awareness and self-confidence in children to actually apply this in their living environment to produce clean energy.
