Hilarious! You describe this utopia that the entire planet should emulate then use the lame politician excuse 'I don't know the economics of anything.'I don't do money or law so the details of how this is all accounted for are out of my scope. I attended a TED talk and what I got was the incentive to subscribe to this scheme is a lower power cost.
So, they charge at night when demand is low. But, if they're running solar then production capability is low as well; remember, it's dark at night. And what do they do when it's dark at night (i.e., solar panels are useless) and the wind isn't blowing (i.e., wind turbines are useless)? I guess no one goes to work the next day?
Me thinks your grand utopia plan needs a bit more research and testing in a real world environment on a scale that means something. Denmark has a population of 5.8M; there are cities in our country that have a larger population than the nation of Denmark. Oh, let's test it in LA then extrapolate that utopia to the other 330+ million people. Sounds half-baked to me,
