Re: Energy storage for wind and solar power

Ah? Should I buy a truck that lets me get my garbage to the dump, haul dirt to my house, carry away the green downfall after storms, and still get me to the store when I need to? Or do I buy a economy car that lets me drive to the store and then rent when i need a truck?

Time Value of Money lets me put numbers to it, but then you have to take in the convenience factor.

How much is that convenience factor worth?

I have seen discussion of "Cradle to Grave" that try to encompass the entire problem. They leave me a little cold, because they too have a convenience factor involved.
