Household consumes energy for a lot of activities : cooking, lighting, heating, cooling, and others. Urban household tends consuming “latest energy” for cooking by LPG, natural gas, solar energy, and electricity, otherwise at the rural remains traditional energy to be applied such as charcoal, firewood and coal briquettes. Urban society tends to use the latest due to preferences of lower expense, environment-friendly, and easy-to-get.

Energy consumption on household increased rapidly, in-line with household income (Pitts dan Ashby, 2011; Miah et al., 2010). While traditional energy consumption such as firewood, kerosene, and charcoal decreased along with increasing household income (Hughes-Cromwick, 1985; World Bank, 2003; Heltberg, 2005; Shittu et al., 2004, Rajmohan dan Weerahewa, 2007).

Other interesting fact that household with information technology mastery as well as their own to communication device such as handphone, landline phone, and personal computer totally consumed less energy  than others who did not. The circumstances describe positive contribution of Information Technology to energy consumption
