Labour vouchers and energy accounting: depreciation?

[Die Neue Zeit]

I have a question regarding both labour vouchers and energy accounting: how will amortization (http://en.wikipedia.org/wiki/Depreciation) and impairment (http://en.wikipedia.org/wiki/Revaluation_of_fixed_assets) be accounted for?

[In capitalist accounting, obviously $$$ is involved, and the following methods are used, among others: straight-line, sum-of-year's-digits, declining balance, activity depreciation, and units-of-production.]

I sorta get the concept of labour vouchers for producing consumer goods, but what about producing capital assets that depreciate (wear and tear)?

[Cult of Reason]

Energy Accounting is, as its name suggests, the accounting of energy degradation ("consumption") for the purpose of managing an abundant economy. It is not a currency; it is not used for exchange (since exchange is silly in an abundant economy). For that reason, amortisation, depreciation, inflation and so on cannot apply.
