What Jim Carroll Saw Coming
Original archive: 2021-11-16 — Trend: The Future of Energy In the Era of Acceleration (Renewables, Storage, MicroGrid, Electric Cars and the Death of Carbon).
In his writing about energy in the era of acceleration, Carroll connected renewables, storage, microgrids and electric vehicles. Those subjects are directly relevant to vehicle-to-grid systems, where a parked EV could sometimes return power to a building or network. Whether that works economically depends on chargers, rules, vehicle warranties and actual usage.
What has changed in the real world
An electric car is a transportation device built around a substantial rechargeable battery. In principle, energy can move in both directions: from the grid into the car while charging, and from the car outward when a compatible vehicle and charger support export. That makes a parked car potentially useful during a local peak or emergency. Yet usable energy depends on the battery’s state of charge, the driver’s next trip and how much reserve the owner wants to keep.
The 2021 Carroll archive connected electric vehicles with storage, microgrids and broader energy change. In the years since, attention has increasingly shifted toward flexible demand and aggregated resources. A neighborhood need not export electricity from every car to benefit: merely postponing charging for a short period can avoid some demand peaks. Export is the more ambitious step because utilities must manage reverse flows, metering, incentives and technical compatibility.
A fact that changes the scale of the question
The Department of Energy describes virtual power plants that combine rooftop solar, customer batteries, electric vehicles and responsive loads to provide grid services. The original source is U.S. Department of Energy. The distinction behind the number or capability matters just as much as the headline: A battery vehicle is potential stored energy; exporting it safely and economically requires a compatible car, charger, tariff and interconnection. The point of introducing the fact here is to show the actual scale of the machinery, knowledge, data or infrastructure involved in this particular voyage. It is not evidence that the imagined 2036 destination is inevitable.
2036: one possible destination
An imagined scene, not an account of an event that has happened.
In a 2036 street, a resident plugs in after dinner. The car asks whether it may keep enough energy for tomorrow’s commute and offer the rest during a two-hour local grid event. The owner agrees to a limited export in exchange for a clear payment. Elsewhere, another driver declines because a long trip is planned. A useful system has to respect both decisions without threatening reliability.
One image captures the possibility: A fleet of plugged-in vehicles helps shave a peak while retaining promised driving range. The conditions behind that image deserve attention. A future built around this capability would also change work, trust, operating costs or personal choices for someone outside the technology industry. That is why this voyage is less about predicting the arrival date of a device and more about understanding the environment that would let it matter. Different communities and businesses could arrive at the same destination at different speeds, or choose a different route altogether.
The detour that could change everything
Battery wear, warranty terms, charger cost, local tariffs and electricity regulations can determine whether exporting power pays. A household might be better served by a stationary battery, and a utility may benefit more from delaying charging than from energy moving back across the meter. Compatibility across manufacturers is far from assured. What sounds like an enormous shared battery has practical limits imposed by mobility itself.
There is no requirement that technical progress and adoption advance together. People may welcome one application and reject another. The most persuasive future is the one that survives comparison with cheaper, simpler or better-understood alternatives. This is also where the archive has value: an old idea can be supported in direction while the timetable, commercial model or surrounding institutions evolve in ways that could not have been obvious at the start. That history deserves to be told rather than edited into perfect hindsight.
The next chapter is still being written
The real signal will be repeatable programs showing how much dependable power is available at peak time after accounting for drivers’ choices and battery reserves. Look for transparent tariffs, verified performance and clear warranty treatment. That is where a vehicle begins to become a grid resource rather than an attractive diagram.
The practical test is this: Require compatible hardware, contracts, warranty coverage and measured grid value The question for the people making choices today is not whether the imagined 2036 scene is visually convincing. It is whether emerging evidence alters a real decision: where to invest, what to build, which safeguards to demand, and which assumptions should be checked again next year. Could fleets unlock vehicle-to-grid economics before private households do? The answer is not locked in. That is what makes tomorrow a voyage worth taking.
