IMO not enough people forecasting plugin-hybrid sales going to 0. Once #EVs reach parity with gas powered cars, hybrid offers very little Image
Furthermore, hybrids don't benefit from lower maintenance costs. OEMs developing hybrids don't necessarily get #EV knowledge

1/Here's a thread to send to people when they quote the media saying there is an EV slowdown. Add your comments/takes so it can be a useful resource.

Why is the media claiming an EV slowdown?
It's a case of missing the forrest for the trees.
2/Year over year EV sales growth is decelerating.
113% in 2021
59% in 2022
28% in 2023
That's the trees. It's the wrong thing to look at.

What should you look at? Image
3/Market share! Gas vehicle sales peaked in 2017.
And you know what happens with an adoption curve? Image

1/A lot of people talking energy storage/megapack so here is a quick thread for those wanting to follow along/if you want to contribute:

ARK's 2019 analysis sizing the energy storage market at $800 billion, but bigger if battery prices go below $150/kWh…
2/Another good resource to look at is Lazard's levelized cost of storage:…

It has their key assumptions:
3/Battery prices are becoming easier to pin down, but with large stationary projects it's important to look at the balance of system costs.

An old McKinsey piece has a dated look at that breakdown:

1/Do we live in a linear world?

This is global battery electric vehicle sales.

The question is where do we go from here?
2/You can fit a diffusion curve to EV adoption quite well:
3/That diffusion curve suggests roughly 59 million EVs sold globally in 2027, which is in line with ARK's expectations.

A linear forecast of the past few years suggests ~21 million EVs sold globally and is in line with some other EV forecasts.

1/@VitalikButerin Would love to discuss and share our modeling.

It ultimately comes down to a different business model and lower/negative electricity prices.
2/One instructive analogy could be a Hollywood Studio vs Amazon Prime.

Hollywood studio needs hits b/c that's its whole business. Looks at Amazon Prime spending as irrational on cost per viewership. But Prime is part of a suite of services.
3/If Prime video content attracts and retains marginal customers across its entire suite of services, which extend far beyond video streaming, then Amazon’s content spend—seemingly unprofitable from a Hollywood mogul’s perspective—is entirely rational.

1/What is current demand for vehicles?

The University of Michigan Consumer Sentiment Survey asks: Do you think the next 12 months or so will be a good time or a bad time to buy a new vehicle?

More people than ever said "Bad Time" going all the way back to 1961.
2/But automakers claim demand is strong and point to low inventory on dealer lots.

But is inventory on dealer lots? How much inventory is in people's driveways after buying a car to avoid public transport during COVID?
3/As semiconductors arrive, can selling a low number of cars quickly be linearly extrapolated to selling a high number of cars quickly?

There is also a shift in consumer preference towards electric vehicles. Will the incremental buyer want a gas-powered vehicle or an EV?

1/2021 battery electric vehicle(BEV) thread with data from ev-volumes

The BEV market grew 112% yoy. It hasn't grown this quickly since 2012, which is pretty much the start of the modern BEV era

and it looks clear that incremental demand is for electric not gas powered vehicles.
2/There were roughly 4.8 million BEVs sold in 2021.
3/Micomobility is making its mark on the industry. The Wuling Mini EV went from selling ~123,000 units in 2020 to ~439,000 units in 2021.
