He completely ignores the importance of local load differences, and seems to assume there is a loss-less, instantaneous transfer of energy across the national grid, both transmission and distribution channels, with no limitations.
Does he? His only claim here is that both supply and demand can be predicted, and that these can be choreographed to optimize utilization. He mentions that current power generation technologies are not available 100% of the time and proposes that the predictable variability of renewable power would be functionally no different. Nowhere does his proposal require loss-less, instantaneous, unlimited transmission of power.
He also doesn't get that even at a local level things like AC compressors are already averaged out and that delaying the timing of starts really makes almost no difference at the neighborhood level, much less a town level.
How are, for example, all of the AC units in a particular neighborhood "averaged out"? That makes no sense. There is no communication between these units. It's also not a matter of delaying the start times, it's a matter of remotely disabling them entirely - across entire neighborhoods - to shave peak demands.
Its nice to completely ignore realities like overall cost.
So what ARE those costs, versus the cost of business as usual? Just because the article doesn't go into that kind of depth does not mean it hasn't been considered at all.
Its nice to not realize that industrial areas have a significantly different profile than urban areas, and that rural areas are vastly different.
Largely Irrelevant here; Of course different regions are going to have different characteristics, but you can still model and predict the behaviors of each region and the system as a whole. Other countries manage to do it, and there's no reason the US can't do it as well.
Its nice to call yourself and energy expert and get submitted to slashdot by those that believe you just because they want to, or because you fall in line with their agenda.
It's also nice to rant about things you don't agree with while not providing any of the expertise you criticize others for claiming.
Credible experts are people who understand what they know, and what they don't know.
Unlike, say, Slashdot users who of course are experts in everything...
