let's put the electrical power systems together these electrical power 00:22:29 systems that this is actually on the low side because most industrial action happens with the consumption of coal and gas on site and then it's converted to energy on site this is what's just been drawn off the power grid 00:22:42 so there's a vast amount of energy associated with manufacturing that is not included here and that is actually a huge piece of work to include that so these numbers i'm showing you are very much on the low side 00:22:55 so we're going to put it all together we need 36 000 terawatt hours all there abouts that's a that's a very low estimate
