Electrical From Hill

In Indonesia have many places with up and down level and often time have water source at the hill so this water source can be used as agriculture and domestic use. Indonesia also have many volcano, especially in Java even some volcano look not active anymore. Electric source can come from water fall and also can come from heat of the earth like on the volcano.

One of the volcano heat energy that have processed into electrical energy is Sibayak mountain with 2,172 meter height named geothermal power plant. Geothermal power plant in Sibayak mountain have produced electric with capacity about 10 megawatt (MW) and have potentially be increased into 40 MW.

All the electrical energy is come from nature source even the energy source is come from fuel oil but ironically Electrical Department from Indonesia said deficit, even the electric to domestic is not free. People always pay every month and the electric come on and on from the nature but the Electric company always deficit, We don't understand this.
