On: All poverty is energy poverty

[NavinF]

You ignored inverter, battery, battery replacement, and installation costs. All that has to be amortized along with the interest rate or opportunity cost of tying up your capital.

There a lot of refrigerators cheaper than $800 and just about all of them cost more to power than to buy.

The elements ignored in OP only further amplify the point that capital in addition to energy is required.

This makes gizmo686's argument stronger, not weaker.
