The electricity crisis in Indonesia can be averted with comprehensive planning, management of energy systems (demand-side management), efforts to utilize alternative energy sources and energy conservation. Dependence on fossil energy sources should be reduced and on the other hand, the utilization of new and renewable energy sources should increase. In the long term, fossil energy use must decline given the petroleum depletion and environmental unsustainability [1][2][3]. Indonesia is one of the countries that has committed to reducing greenhouse gas emissions (GHG) to 29% below business as usual by 2030 or a 41% reduction target contingent on sufficient international financial support.
