Apologies if anyone has brought this up, but has anyone got info or comments on ‘mine to mouth’. It seems we discuss EROEI to death, but rarely ‘mine to mouth’.

For example, A coal mine is developed, mined, the coal is graded and loaded into a truck and taken 50 miles along a road to a power station, where it’s pulverised, used to make steam to turn turbines, generate electricity, pass through step up transformers, travel 200 miles, pass through step down transformers, into a house to power a ligtbulb.

It has been argued that the power loss in this process is as high as 97%!

In another example, a household mini wind turbine generates the power, constructed out of cheap materials in a factory 200 miles away, transported by tuck, bought in a store, transported by car 5 miles, and wired and fitted.

It has been argued in this process the power loss is only 10%!

Discuss.

This is why an Amish farmer with his horse, lives so well!!

We meanwhile run harder and harder in the hamster wheel for less and less.
