Slovak Republic and Taiwan R.O.C. have both similarities in geomorphologic landscape structures and urban divisions that create notable energy potential premises. They also are facing similar energy deficiency issues. Large population difference makes also premises for good prognosis study. Both countries are viably engaged in research on renewable resources. Proposed idea is dealing with the energy resource decentralization caused by not underestimated development of micro-urbanism, applying the autarchic grids arranged in the idea of ‘electric power grid circles’ binding micro-urban structures together and at the same time creates smart energy communities using renewable energy micro-systems. Current water turbine’s efficiency rose up to 96%. Proposed multi-purpose micro-hydro type might be one of the reliable renewable resources applicable in this kind of situations.
