That's my point: electrifying heating and transportation will increase electricity use beyond the current 2.5Tw and make it even harder to provision the same duration of grid storage. I added the content in parentheses in case this was unclear.
Higher electricity demand is a problem is you're trying to. Build grid storage. And no, not everyone is onboard with the idea that battery cost is going to plunge by orders of magnitude. In fact, the opposite trend is happening. Battery costs have increased recently: https://www.utilitydive.com/news/new-york-battery-storage-co...
> the state's higher storage target and DPS and grid operator support will slash costs to $150-$200 kWh by the end of the decade, based on BloombergNEF estimates.
They have dropped an order of magnitude since 2008, so I'd maybe expect a few more years before it does it again but that does appear to be the current prediction.
If their predictions are that costs are going to decrease, but when push comes to shove costs increase above expectations then what does that say about the value of these predictions?
