The usage of renewable energy sources (RESs) has become popular in order to avoid<br />

insufficient of non-RESs materials. Nowadays most of the countries have replaced RESs<br />

as their main sources energy for nation development. In this research, we develop causes<br />

and effects factors that influence RESs and find out the ultimate RESs. VIKOR method<br />

was used for ranking and figure out the optimal RESs, while DEMATEL method was<br />

applied to find out the causes and effects among 10 factors. The data was collected<br />

through questionnaire and online database from SEDA websites for analyse. MATLAB<br />

software was chosen to test the efficiency of the model. From the results, social<br />

acceptability, social benefits, investment costs, and reliability factors are the causes that<br />

affect RESs. Solar energy was the ultimate renewable energy systems among RESs. This<br />

research could be valuable references for sustainable energy development of countries.<br />
