Another unrenewable energy resource that has high energy efficiency is Uranium.  Comparing with Coal, Uranium come to an amazing comparation, i.e., 1 : 1000.  It means for 1 kg of Uranium producing energy as much as 1 ton of Coal.  Uranium is used in Nuclear Power Plant.

In Indonesia, the nuclear power development for commercial scale is in promotion stage.  In some developed countries, the contribution of Nuclear power is significant in supplying cheap electrical energy.
