Energy is a vital factor in our everyday life. People use energy for transportation, cooking, air conditioning, watching TV, using computer, charging phone and for many other activities. Nowadays, the dependency on energy is very high, without energy, the economy or even health could be dangerously threatened. With an evermore increase of energy demand, the energy supply is struggling to fulfil the demand. In Indonesia, energy sector is still dominated by fossil fuel, which is a nonrenewable source that depleted each day. Moreover, people are becoming more aware of the environment, some of them already make efforts to reduce their carbon emissions, and with energy prices continuing to rise, many people are keen to do something. Therefore, a strategic plan to maintain energy consumption is urgently needed, not only from the government but also from the consumer.
