Energy Power Plants
Predominantly, natural resources are used to produce energy. The safest and cleanest energy source to use is Electricity from Solar heat and radiation (sun energy). However, the methods to produce electricity have traditionally not been so "clean", such as, the burning of fossil fuels using generators or turbines.
However other methodologies exist that will not pollute as in the above examples and these are:
When Generators are turned by the forces of potential energy, wind or by the burning of fossil fuels through the expansion of oxidised gases, the mechanical efficiencies (losses due to friction) of pistons and other moving parts reduce the full potential of total energy recovery from the fuel source. Also as in the burning of fossil fuels, the heat dissipated as a consequence of combustion (oxidation) is not fully recoverable and in most cases wasted, through the lack of planning or economic factors. Although heat recovery is a basis of increasing efficiencies in order to conserve or decrease costs, it generally has not been considered economical for small systems. Example of heat recovery are found here >>>>>
As a consequence, the "Solar PV" method of producing clean elctricity has been deemed as the "Rolls Royce" method of producing clean energy, as it requires no moving parts (except when tracker are used). However this technology presently accounts for less than 1% of the total energy currently produced, mainly due to costs associated with the production. Even though the lowest cost per Wp (Watt peak) is US$4.25 (solarbuzz.com) for multicrysaline and $3.69/Wp for thin film presently (November 2007), it still is an expensive way to produce electricity as compared to the ever increasing price of fossil fuels and other methodologies as menioned above for various reasons.
Afghanistan has a few Dams that produces power and a few large generators that currently are idle. There are also other methods such as solar power and chemical and nuclear power methodologies, which are presently not feasible for one reason or another. Solar panels are too expensive even though Afghanistan has an abundance of sunlight during the year. The expense is due because most production facilities have been bought out by large mutinational oil companies such as BP, Sheel etc. Nuclear Power is not a feasible alternative as the country does not have the money nor the expertise to erect such a complicated tecnology. It is also a dangerous technology as Afghanistan suffers from many earthquakes.

The gas consumption rate of 0.34 normal cubic meter (Nm3)/kWh is based upon actual data from the Uran gas turbines. The economic cost of gas, Rs 2,300/1000 Nm3 (1992 Rs33=$1) $69/1000m3, is essentially based on the concept of parity to fuel oil, with the border price of fuel oil at $14/bbl. The resultant estimate of busbar avoided energy cost on-peak is Rs 0.81/kWh
