The process has a high energy consumption, for example around 2,500 kWh (9,000 MJ) of electricity per tonne of sodium hydroxide produced. Because the process yields equivalent amounts of chlorine and sodium hydroxide (two moles of sodium hydroxide per mole of chlorine), it is necessary to find a use for these products in the same proportion.
In 2008, Australia's oil shale resource was estimated at 4.531 billion metric tons of oil shale equal to 31.7 billion barrels (5.04 × 10 9 cubic metres) of shale oil, of which about 24 billion barrels (3.8 billion cubic metres) is recoverable. [15]

Since this is a measurement of mass, any conversion to barrels of oil equivalent depends on the density of the oil in question, as well as the energy content. Typically 1 tonne of oil has a volume of 1.08 to 1.19 cubic metres (6.8 to 7.5 bbl).
The most important of these are located at Tarfaya (in the south-westernmost part of Morocco) and Timahdit (in the Middle Atlas Mountains). [4] The largest known oil shale deposit in Morocco is located at Tarfaya. The deposit is estimated to consist of 80 billion tons of oil shale, containing 22.7 billion barrels (3.61 × 10 ^ 9 m 3) of shale ...
In April 2010, the Norwegian state-owned salmon company EWOS stopped the purchases of fish oil from Western Sahara and Morocco (with an amount of around 10 million euros annually, and estimated between 12,000 and 20,000 tons of fish oil in total), [9] for "not being in line with the Norwegian authorities' recommendations".
