Utilization of geothermal energy is relatively environmentally friendly, especially because it does not contribute to greenhouse gas, consequently, it is necessary to spur and accelerate the materialization thereof. The utilization of geothermal energy will reduce dependence on fuel oil so as to be able to save petroleum reserves.
· Consumption of 1 MWh requires 1.7 barrels of Fuel Oil, 390 kgs of coal and 7.9 Mcf of natural gas. Retrenchment of 1 MWh, it is estimated that geothermal power plant can save the use of Fuel Oil of 45 barrels per day.
· As renewable energy, geothermal energy can be counted on as a long-term supply. Some Geothermal Power Plants (PLTP) are still in production after 100 years in New Zealand and are still in production in Latin America after 50 years and are already in production for 21 years in Kamojang.
· Its character is naturally renewable
· Environmentally friendly (very tiny environmental impact)
· Reliable (high load factor)
· Non dependent on season
· Flexible in terms of generation capacity (various types of generators are available)
· Utilization of geothermal energy can save the use of fossil fuel.
· Greenhouse gas emission is very little as compared to other sources of energy.
· There are no NOx and SO2 gas emissions
· Production process does not generate effluent.
The importance of developing geothermal energy:
· Needs for energy (electricity) keep increasing
· Limited and decreased fossil energy reserves (oil and gas, coal)
· The potential of geothermal energy is very huge (27,000 MW), the utilization thereof is not optimum yet (3%)
· Naturally renewable
· Environmentally friendly (very low gas emission, there is no effluent)
· The development of geothermal energy will reduce dependence on sources of fossil energy (oil and gas)
