Hi Frederick

problem is we only ‘’know’’ profit

that is the basis of all our commerce.

we cannot function at a net loss or the energy system collapses in on itself.

‘economics’ means continual energy input — -surplus energy input. Income also means energy, because money is only a token of energy exchange

If we have no energy, or a shortage of it, then income cannot exist except by barter

Cities are merely blocks of embodied energy (as is a house) it isn’t possible to build a city without availability of surplus and cheap energy

as a final point — — energy has allowed us to have cheap technology

but technology will not allow us to have cheap surplus energy.

If Ive missed a trick somewhere, let me know — -what I am saying is truly depressing — -i wish it wasn’t so
