But is that something people really need? To be able to audit their electricity transactions via the blockchain? Someone is going to have to write a tool (this is well beyond the average person), and that tool could easily be flawed. The meters themselves also aren't easily auditable... so many points of failure why is a blockchain the thing that matters?

What tooling exists for me to aggregate my electricity costs against anonymous wallet hashes and see the unique amounts to each neighbor?

Disclaimer: never used BC. I meant BC and ETH are generic data structure, you put anything you want in it and retrieve later to create a new transaction.

Regardless of the actual coin, where's the tooling for the enduser to do this verification? They go to there computer and... what happens?

This has to be built by someone, and then that has to be trusted. I can't imagine many people wanting to do such a thing on any side...
