Consumers and companies demanding full traceability in their financial dealings, as well as many of their consumer product purchases is nothing new. But it's still not common in the energy sector.  So typically, even if you are paying for green power, the actual electrons delivered into your home may still be from fossil fuel sources.

Enosi are introducing full traceability for green electrons from source to socket, delivering consumer confidence the electrons they have purchased & are using are 100% green. Importantly, it can all apparently be done without energy intensive block-chain tech - just a smart meter and Powertracer software.
