Tesla TERAWATT Goal is Masterplan 4

by

Tesla Master plan 3 targeted a global installation of 30 terawatts (TW) of renewable energy capacity, primarily from solar and wind. This is a monumental scale-up aimed at meeting all energy needs across electricity, transportation, and heating. It involved extensive Battery Storage: It proposes 240 terawatt-hours (TWh) of battery storage worldwide to ensure consistent energy supply, addressing the intermittency of renewables like solar and wind.

A Tesla Terawatt plan is a more focused XAI and Tesla Master Plan 4. It would be doubling the electricity generation of the USA for the purpose of powering a monster AI data center. The Terawatt goal is a smaller but still huge energy goal but it also involves scaling up AI chip production and AI memory production and AI data centers by about 100 times.

If this was attempted with 1000 nuclear reactors it would mean ten times more nuclear reactors than the US has now and about 20 times more than China has now. Cooling those nuclear reactors would need 7 million tons of water each minute. It would be a literal major river of water.

One billion chip AI data center would be a stepping stone to one trillion chips.

XAI is completing a one million chip AI data center in the next 12 months.

Tesla Master Plan 3

For the United States, the plan includes approximately 3 TW of solar, 1.9 TW of wind, and 6.5 TWh of battery storage, tailored to meet the nation’s energy demands sustainably.

Tesla estimated a global investment of $10 trillion, which is less than the $14 trillion projected for fossil fuel spending over the next two decades, making it economically viable. It also ensures material availability for this transition.

Doubling US Electricity but All for XAI and Tesla Data Centers

The U.S. currently generates approximately 4,243 TWh of electricity annually (based on 2022 data). Doubling this to 8,486 TWh per year would require a significant increase in generation capacity—roughly doubling the existing ~1,200 GW of installed capacity to ~2,400 GW, assuming current utilization rates.

Energy Output: Doubling U.S. electricity generation would increase annual output to 8,486 TWh, a substantial jump but far smaller than the global energy transformation in Master Plan 3. For the U.S. alone, the plan’s renewable capacity (3 TW solar + 1.9 TW wind = ~4.9 TW) could generate significantly more than 8,486 TWh annually with appropriate capacity factors (e.g., 25% for solar, 40% for wind), potentially exceeding 10,000 TWh/year, surpassing mere doubling.

Doubling generation focuses solely on electricity production, likely using a mix of existing sources (fossil fuels, nuclear, renewables).

Doubling would require new power plants and grid upgrades. However, Elon Musk has talked about using millions of Megapacks so that existing power plants could run at maximum output at all times. Generating even at night and other low demand times. This would mean more coal, natural gas and other fuel sources for the fuel burning power plants.

  2. Even with a trillion top end AI chips will it be able to answer the ultimate question about life, the universe and everything?

  3. 3 TW solar + 1.9 TW wind

    Normally Solar is about 10% capacity factor, so I get 1,06 TWyear/year

    1 TWyear = 8760 TWh

      • [ (partly?) change from TESS (thermal energy storage) to battery storage ~2019-2023 for an Australian project (from original SolarReserve) with combined concentrated solar (CSP, 150MW), photovoltaic solar (PV 70MW) and battery storage (2023 ~280MWh, 140MW), and maybe? thermal GRID-TESS (would have been 1.2GWh molten salt energy storage, maturity difficulties with the tank ~2020):

  4. There are a number of low energy specialized LLM chips coming online now with equal performance to Nvidea’s chips. Nvidea is not as invulnerable as it seems.

    • The real moat that Nvidia has is the proprietary CUDA software platform that dominates AI development. It’s not really a hardware thing, it’s how locked in everyone is to CUDA. It was around longer and became the standard. Standards aren’t completely invulnerable but close.

  6. So is Tesla going to use their own money for these grandiose plans or do they expect the hapless consumer and taxpayer to foot the bill?

    Batteries cannot match the grid stability features of large rotating machines.

  7. If the cooling water of reactors are in closed loop, you need a negligible amount of water used in nuclear reactors, if you use Aeros. Also using cooling towers, the amount of water is not a Big deal.

    • water use is only “negligible” for ultimate heat sink if using an air-cooled condenser. Cooling tower cuts down water use by 2/3 from once-through (i.e. putting the river through the condenser). They aren’t used to the best of my knowledge. They are less efficient, and necessarily larger to reject the same heat as a water-cooled condenser.

      There have been some air cooled cars, but most use… water (in a closed loop).

            • [ depending on the scale (Kardashev?), heat (from matter to energy conversion) will get the ‘problem’, because of ‘limited’ surface of the planet (outer atmosphere) and an (for a lot of the biological forms of life) overheated balanced system(?)

              *and store it*(?) prospective appearance of that storage technology? ]

  8. Even if batteries could theoretically solve the problem of intermittency (I’d like to see the actual cost), solar and wind are much less dense forms of energy than nuclear and would therefore require huge areas to be deployed. It’s nonsense. We’re only doing it because it’s fashionable.

  9. The main problem with such ideas is not even the scale of power generation required, but the life cycle of the project. There is no energy tech at such power level that is viable with a five-year project life cycle. The obvious conclusion is to limit power and increase life cycle – same result but slower. As if adults would need a reminder about limits in physical reality, trees don’t grow into space.

  10. Convenient that the insatiable power hunger from current and future datacenters creates a golden oppertunity for Tesla Battery storage bussiness.

  11. Would it be possible to put solar powered data centers in space?

    Would the cooling be a problem?

  12. I’m surprised compressed air and rotational inertia devices aren’t more competitive with grid scale batteries. The rotational devices in particular would be useful to maintain frequency – thinking about the recent blackout in Spain/Portugal.

    • I don’t know about that, Jello.

      Using an analogy, it has been proposed a whole lot of times that using straight up gravity would be a good way: either lifting giant rock-and-concrete blocks on rails up sides of mountains, topped off to be a flat storage area, upon which one could reasonably pile hundreds-of-thousands of the things. Piling them back on the motor-generator cars and letting them back down the mountain gets the stored energy back. Fairly efficiently. 85% round-trip!

      The problem becomes the logistics-costs of making the tens of thousands of the blocks, and coming up with some sort of energy-and-complexity efficient way of dealing with Futbol statdium loads (cubic football stadiums!) for ‘charging’ and ‘discharging’ as needed, at both ends. They’re bulky.

      Obviously, one might then conspire to pump sea water up coastal mountain ranges, and fill up reservoirs. Discharge is happy-snappy, let it come back down. Motor-generators do the heavy lifting. Efficiency is said to be around 73%. OK, I like that. Barnacles be damned.

      And of course as you point out compressed air. Turns out that it works fairly well, but has a certain ‘it is prone to leak’ and ‘if you put too much down there, it could right-out blow up’. That is not a great idea. But here in California, we apparently have at least 2 and maybe 3 of them, at full utility scale. So, there’s that.

      Finally, in the gravity-storage world, there’re tethered undersea gasbags. They’re isothermal, given the sea water; being far underwater compresses the air, and yet is nearly iso-static pressure wise. Tethering them to the bottom however is something of a mystery, as they do have an enormous amount of buoyancy. And lemme tell ya, you would not want to let one of them get away. The awesome side though is that they’d be particularly inexpensive at the very largest scales. Lots of sea-water our there.

      So, gravity and proxy-gravity storage. I would be on your side of the bench at the Congressional Hearing, were there to be one.
