It has been a big few weeks for smart electrical panel-maker Span. The company announced major deals with Pulte Homes and utilities with Landis + Gyr. The startup also expanded its lineup to include small home and apartment-sized panels and even subpanels

But firstly, why do we even need $3500 smart electric panels?

We last caught up to Span last year when they announced a smart EV charger and funding.

Founded by the former head of Powerwall development and Tesla Energy Arch Rao, Span has been creating smart circuit breaker boxes for homes for a few years.

Rao left Tesla in 2018 at a tumultuous time when Tesla was diverting Gigafactory Nevada batteries from home storage into its new Model 3 and was also fumbling its solar roof efforts while managing its controversial Solar City acquisition.

Span smart circuit boxes were launched in 2020 at a price of $7000 and require specialized electrician installations in low numbers.

Since then, the price has halved to $3500 (or $2900 after the IRA tax credit), and the number of Span installers has expanded, leading to much lower costs and, with this week’s announcements, much-expanded capabilities.

Why Span smart circuit breaker boxes?

As people dump petroleum-based vehicles and home heating and move to EVs and heat pumps, the electrical service lines that homes use are getting taxed. Even 240V/200A service, which a few years ago was very high end, can almost entirely be used up by a few EVs and a whole-house heat pump system. An 80A EV charger will take close to half of 200A service.

With dumb panels, electricians are limited to those 200A, or they’re forced to bring in more power from the street, which can cost thousands or even tens of thousands of dollars along with a lot of time and effort.

Enter the smart panel. Span panels can monitor home power usage and turn off high-power-use items like car chargers, pool pumps, and water heaters when the capacity starts to fill up. Users can set priorities, and there are 32 different smart breakers to wire up many household items.

Solar and Batteries

It isn’t just EVs and heat pumps that are going into new homes. More and more people are looking to solar and battery storage to help mitigate energy costs and outages. These each require a huge breaker and, on dumb panels, eat into those allotted 200A.

Span helps manage these pieces of technology as well. Span can set the home to be run off solar and save energy-intensive operations like charging EVs and Powerwalls for low-energy-cost timeframes.

Obviously, with Rao’s history with Tesla, Powerwalls, Tesla inverters, solar panels, and gateways are fully supported. But other major batteries, such as Franklin WH, Enphase IQ Battery, and LG Chem RESU2 SolarEdge Energy Bank, are also supported.

Span Announcements

Span announced this week that smaller 24-circuit and 16-circuit model boxes are available for smaller homes, apartments, and commercial usage. These can also be utilized as smart subpanels, and there’s even a panel with a built-in meter that is being tested and readied by utilities (details forthcoming).

Span expands

There’s also a bigger 48-breaker panel coming for new homes. Prices aren’t set yet, and obviously, installers will get discounted prices in bulk.

More announcements are expected in the next few months, which should be exciting for Span.

Electrek’s take:

As I’ve added solar, batteries, EVs, and heat pumps, not just for HVAC but also for water heating and clothes washing, I’m feeling the strain on my 200A service. Our electrician initially recommended running another 200A line that would cost over $10,000. Another option was only having 1 EV charger (which we split with a Neocharge)

Installing a Span will run a fraction of the cost, allow us to add EV chargers and, as a bonus, will allow me to better monitor and control the loads going into and out of my home. That will also save money in the short term and we’ll likely be able to move to better rate plans in the longer term.

I’m fairly confident that I won’t need to do much in the way of mitigation because our house, when not heating and car charging, uses less than 2kW of electricity out of the 50kW coming in. We’ve also removed 240V dryers and replaced them with 120V heat pump modelss and are moving from a 240V water heater to a 120V heat pump water heater.

I’ll have a review of the Span after my upgrade is done in a few months.

Electricity is about to become the new base currency and China figured it out

Electricity is about to become the new base currency and China figured it out

For most of human history, currency was a direct claim on tangible, productive output. Before the abstraction of government fiat or cryptocurrency, value was stored in things that required real work and resources, bushels of grain, livestock, gold, assets with their own direct productive output: horses, and tragically, slaves.

These were the foundational assets of economies, representing a direct link between labor, resources, and stored value.

As we accelerate into an all-electric, all-digital age, this fundamental link is re-emerging, but with a new unit of account. The 21st-century economy, defined by automated industry, robotic, electric transport, and now power-hungry artificial intelligence, runs on a single, non-negotiable input: electricity. In this new paradigm, the real base currency, the ultimate representation of productive capacity, is the kilowatt-hour (kWh).

The kWh is the new economic base layer.

Last week, I was in Bijiashan Park at night overlooking Shenzhen, arguably the most technologically advanced city on earth, built over the previous few decades, partly on cheap electricity, cheap labor, and manufacturing innovations.

I could see the giant high-voltage power lines coming over Yinhu Mountain to power the constant light show that is Shenzhen at night. I couldn’t help but think about how cheap electricity and a strong grid have been critical to China’s exceptional economic rise.

As you stroll around the city, you see power everywhere. There are charging stations at every corner, including insane 1 MW charging posts, electric cars and trucks, trucks that carry batteries to electric scooter shops, which are also literally everywhere.

Everything moves on electric power. Industries are powered by electricity, and now, with the advent of AI, virtually everything is increasingly processed by LLMs, which are ultimately powered by electricity through power-hungry data centers.

In a world where everything runs on electricity, electricity itself becomes the currency of civilization.

It is measurable, divisible, storable, and universal – all qualities that a currency needs, but unlike fiat and crypto, it’s actually directly linked to productive output. No politics. No inflation. Just physics.

This concept is not merely academic; it appears to be the quiet, guiding principle in China. While others debate the merits of decentralized digital tokens, China is executing a multi-pronged strategy that treats electricity as the foundational strategic asset it has become.

First, China is building the “mint” for this new currency at an incredible, world-changing scale, and it has retained absolute state control over its distribution. Its deployment of new electricity generation, particularly from renewables, is staggering. The country met its 2030 target of 1,200 gigawatts of renewable capacity five years early, in 2025.

In 2024 alone, renewable energy accounted for a record 56% of the nation’s total installed capacity, with clean generation meeting 84% of all new demand.

Here’s a comparison of electricity generation between China and the US:

If this chart doesn’t scare the West. I don’t know what will. The trend is not reversing any time soon. In fact, it appears to be accelerating as China is doubling down on solar and nuclear.

State-owned monoliths manage this entire system, primarily the State Grid Corporation of China (SGCC), the world’s largest utility. For better or worse, this centralized control allows the state to execute massive national strategies impossible in a liberalized market, such as building an Ultra-High-Voltage (UHV) grid to transmit power from remote solar and wind farms in the west to the power-hungry industrial hubs on its coast.

Second, China wields its control over the grid as a precision tool of industrial policy. China’s average electricity rate of $0.084/kWh is cheaper than most of the rest of the world, but its power lies not in the base price but in its strategic application. The government deploys a “Differential Electricity Pricing” policy: a “stick” that penalizes low-tech, high-consumption industries with higher rates, and a “carrot” that provides preferential pricing to incentivize strategic sectors.

The most potent example is in the AI sector. China is now offering massive electricity subsidies, cutting power bills by up to half, for data centers run by giants like Alibaba and Tencent. The condition for this cheap power is that these companies must use locally-made, Chinese AI chips, such as those from Huawei.

China is spending its “electricity currency” to directly fund the growth of its domestic AI chip industry and sever its dependence on foreign technology. This same logic applies to its global dominance in green tech, where state-subsidized firms like BYD benefit from a state-controlled industrial ecosystem built on reliable, managed power.

Third, and possibly the most explicit exemplification of China viewing electricity as the base currency is its moves against cryptocurrency.

In 2021, the government banned all cryptocurrency transactions and mining. While the official reasons cited financial stability, the move might have had a deeper, strategic intention.

From the state’s perspective, it was a tool for capital flight, allowing wealth to bypass government controls. But in a world where electricity rules, cryptocurrencies are, in effect, a competing “currency” that burns the foundational asset (electricity) to create a decentralized store of value.

By banning crypto, China simultaneously reclaimed its monopoly on economic control and shut down a massive, “wasteful” leak of its most precious resource. It freed up that generating capacity to be strategically allocated to its preferred industries, like AI and manufacturing.

China’s actions, viewed together, are a clear and coherent strategy. By massively investing in and securing total state control over its domestic electricity supply (the “mint”), using its price as a tool to fuel strategic industries, and banning decentralized competitors that consume the same resource, China is making a clear bet. It has been recognized that in an age where all productivity is powered by the grid, the ultimate source of national power is not gold, fiat, or crypto, but the state-controlled kilowatt-hour.

The Blockchain and Crypto: Ledger vs. Furnace

This perspective brings a critical nuance to the role of blockchain technology. In an economy where electricity is the base currency, the blockchain makes perfect sense, but only as a ledger, not as a store of value.

A distributed ledger is the ideal technological layer to act as the accounting system for this new economy. It can track the generation, transmission, and consumption of every kilowatt-hour with perfect transparency. It can automate complex industrial contracts and manage the grid’s load balancing without a central intermediary. In this sense, blockchain is the “banking software” for the electricity standard.

However, “Proof of Work” cryptocurrencies like Bitcoin face a fatal contradiction within this paradigm. They aim to serve as a store of value by burning the base currency (electricity) to secure the network. If the kilowatt-hour is the 21st-century equivalent of gold, then Bitcoin mining is akin to melting down gold bars to print a paper receipt. It destroys the productive asset to create a derivative token.

Bitcoin is quickly losing credibility as a classical safe store of value. It trades like a security, at least over the last year, and its value is only whatever the next moron is willing to pay, with no valuable asset behind it.

China’s strategy reflects this precise understanding. While they ruthlessly banned Bitcoin mining (the “furnace” that wastes the asset), they have simultaneously championed the Blockchain-based Service Network (BSN) and the Digital Yuan. They have embraced the ledger to track and control their energy economy, while rejecting the supposed asset that destroys it.

This is a trap that crypto fans often fall into. They recognize the value of the blockchain, which is real, but they mistakenly broadly assign the same value to cryptocurrency, which is simply an application of the blockchain.

Electrek’s Take

What I’m trying to explore in this op-ed is the idea that if the present is electric and the future is even more electric, then it makes sense for electricity to be the foundation of the economy.

If electricity is the backbone of global trade and the metric of productivity, the kWh ultimately becomes the real currency of a truly electrified world.

And I think China has figured this out, as evidenced by its new electricity generation surpassing the rest of the world combined and by its ban on cryptocurrency.

They are going to let the rest of the world hold the crypto bag while they have more electricity generation than anyone to power their industries, which are already taking over the world.

I think the rest of the world should learn from this. Instead of pouring capital into meme coins and made-up stores of value, we should invest in electricity generation and storage.

Oil prices and energy stocks fall sharply on Trump’s new Ukraine peace plan

Oil prices extended declines and energy stocks fell sharply on Friday morning as U.S. President Donald Trump pushed for a peace deal to end the long-running Russia-Ukraine war.

International benchmark Brent crude futures with January expiry slipped 2% to $62.09 per barrel at 11:02 a.m. London time (6:02 a.m. ET), after dipping 0.2% in the previous session. The contract is down more 16% so far this year.

U.S. West Texas Intermediate futures with January expiry were last seen 2.4% lower at $57.61, after closing Thursday off 0.5%.

Europe’s Stoxx Oil and Gas index, meanwhile, led losses during morning deals, down more than 2.7%. Britain’s Shell and BP were both trading around 1.6% lower, while Germany’s Siemens Energy fell more than 8%.

U.S. oil giants Exxon Mobil and Chevron were 0.4% and 0.2% lower, respectively, during premarket trade.

The bearish market sentiment comes as investors pore over the details of the Trump administration’s push to secure a peace deal between Russia and Ukraine.

The U.S., under a widely leaked plan, has reportedly proposed that Ukraine cede land including Crimea, Luhansk and Donetsk, and pledge never to join the NATO military alliance.

The plan also says Kyiv will receive “reliable” security guarantees, while the size of the Ukrainian Armed Forces will be limited to 600,000 personnel, according to The Associated Press, which obtained a copy of the draft proposal. CNBC has not been able to independently verify the report.

Analysts were doubtful that the peace plan, which is thought to be favorable toward Russia, would be backed by Ukraine.

Guntram Wolff, senior fellow at Bruegel, a Brussels-based think tank, was among those skeptical about whether the proposed peace plan could lead to a deal.

“I think it’s always good to talk each other so in that sense it’s a good development but I have to say when I saw the details of this supposed peace plan, I really don’t think it can fly,” Wolff told CNBC’s “Europe Early Edition” on Friday.

“Because at the core, what it says is that Ukraine should give up significant parts of its military personnel, meaning the military personnel would decrease by something like a third from 900,000 to 600,000,” he added.

Alongside the peace plan noise, energy market participants closely monitored the potential impact of U.S. sanctions against Russian oil producers Rosneft and Lukoil, with the measures taking effect from Friday, a stronger U.S. dollar and expectations for the Federal Reserve’s upcoming interest rate decision.
