This is a view of the future of energy from a solar booster, but it's an interesting read even if it is a little biased.
Less developed markets are pointing the way – Pakistan has cut most domestic power consumption over to solar and batteries in about two years. This is analogous to the growth of cell phones in developing countries that never ran copper phone lines to every house.
I really like his angle on data center power consumption:
In 2025, headlines scream that datacenters are pushing prices up and consuming all the power. I think datacenters are exposing the rot in a moribund power generation and delivery industry which has proven unable to meet demand in recent years. But it is a moot point.

"Datacenters will be net power sources for their communities"

It's almost like he's heard some of the arguments bitcoiners have been making about ming and the grid...
And as to grid regulation:
I pre-register my belief here that electricity governance markets will bifurcate. On one side, we’ll see those that embrace a steady cadence of pricing reforms, allowing effective competition between many private operators of generation, storage and transmission assets, pushing prices down. On the other side, increasing prices for consumers will drive increasingly desperate governance measures that allow far less competitive storage operators to extract vast rents from the difference between real world power conditions and the conditions approximated by some legal framework.
Also, he brings up this idea of storing heat in sand...which I had never heard of:
Essentially a giant hair dryer blows hot air into a large pile of sand during the summer months with abundant cheap power. In winter, the fan switches direction, extracting heat. The storage medium can be made almost any size and is self-insulating. You can think of it as artificial geothermal power storage – in fact it has several strengths that geothermal lacks, like the ability to cheaply build and renew stored power.
I don't know if I buy the Terraform Industries vision of ultra cheap solar, but the trend has certainly been towards cheaper solar, and I do love the decentralized nature of solar: solar is probably our best bet for energy self sovereignty.

The only thing really standing in the way of real cheap solar has been protectionism. Started in Europe, then US. Don't buy Chinese solar, because our fully-automated-factory owning billionaires will never become trillionaires then...
but whatevs... suckers be sucking.

I both love this stuff and think it’s mostly pie-in-the-sky silliness.
On the self-sovereignty note, small wind generators are apparently improving. They’ll potentially be better for some situations.
That physical sand-heat battery is neat. There are lots of different options for physical batteries. The most common is using excess energy to pump water into an elevated reservoir, which then spins a turbine as it comes down during energy deficits.

On all fronts the USA is way behind China.
The USA has lost the ability to build physical infrastructure because its entire industrial base has been run down and neglected over decades of neoliberal financialisation and outsourcing to offshore providers.
The USA has lacked a cohesive and strategic industrial and economic development plan. Free markets don't plan for a nation state- only a government can do this but the neoliberal ideology has failed to plan and build the plant, skills and infrastructure required for the US maintain global hegemony. China spent four decades investing strategically in developing its stranglehold over rare earth refining...and multiple other strategic supply chains especially related to energy production and efficiency. Now the USA cannot fight a war of any scale for at least a decade because China hold a monopoly over the supply of the rare earths supply chains needed to build modern war materiel.

blow wind into a pile of sand, what?!
Pretty ridiculous to cherish solar, which is growing (but from ~zero), and dunk on coal and nuclear, which are not. Eeeem, natural gas anyone?!

anyway, I'll take this summary line. Wonderful
The US consumes about 100 quadrillion BTUs of energy per year. Of this, about 80 start life as coal, oil or gas, and roughly a third of the energy mix serves the electrical grid. Less than 1% is food, reflecting our enormous energy wealth in comparison to our pre-industrial forebears.

What have I missed?
China produces more power than US, EU and India combined.
Cheap electricity is what drives Chinese productivity and competitiveness.
For example China makes PVs way cheaper than any other manufacturer...and nuclear and hydro and wind generation...
The government plans and builds power supply and private enterprise comes and consumes it and produces everything cheaper than the crony capitalist west can.
China has won the trade war by producing cheap electricity and now the USA cannot fight a war without Chinas rare earths supply.
In the current race to advance AI China has a massive advantage with its huge electricity supply surplus compared to the US that faces a chronic shortage of new power generation.
Blinded by arrogance US Exceptionalists are their own worst enemies.

We discussed all of this and more at Type I summit!
