We treat all joules as equal and it's slowing down the energy transition.
We just open sourced The Exergy Imperative — a complete guide to the most underused concept in energy.
It explains why measuring Exergy transforms how we make energy decisions.

Clean sources are now meeting all electricity demand growth.
The next milestone is for clean sources to meet all energy demand growth.
The second milestone is much more difficult to achieve, but it's also much more important.
A lot of work left.

20 years of progress:
At the beginning of this century, growth in electricity demand meant growth in fossil fuels.
First wind power, and now solar, have changed this.
Now, solar and other clean sources can structurally meet all growth in demand.

Batteries are the key enabler of the energy transition.
More batteries means:
- A more efficient energy system
- A more reliable energy system
- A more affordable energy system
- Less greenhouse gas emissions
- Less reliance on fossil fuels

Battery storage is now the fastest-growing power tech on Earth: In 2025, we added 110GW of battery capacity in a single year, more than the highest-ever annual capacity additions from natural gas
The storage revolution isn't coming. It is already out-building gas at its peak

This is such a beautiful chart.
Clean power sources are growing faster than electricity demand, which means that fossil fuel generation is declining.
Why this is important:
- Fossil fuels are dirty
- Fossil fuels are inefficient
- Electricity is higher quality than heat

This is one of the most important charts in the world.
It shows how much progress Solar has already made, and how much progress is possible.
99% of people are unaware that Solar provides 1/4th of all electricity during the day right now.
In some countries, it’s nearly 100%.

Fun fact: if generation from clean power sources exceeds demand growth, then that must mean that fossil fuel generation declined.
Are you paying attention yet?

Exergy matching multiplies how much useful work energy is able to deliver.
Studies show that optimizing exergy can roughly double overall efficiency vs. today’s energy system.
Same amount of energy, roughly twice the useful work.
Not enough people are talking about this.

Exergy Destruction = T₀ × Entropy Generation
Our energy systems should aim to destroy less exergy, so that we generate less entropy.
This is the deeper reason to electrify as much of the energy system as possible.

Less exergy destruction means more of the energy that we generate gets converted into useful work, which is exactly what we want.
The more input energy that gets converted into useful work, the better.
Electrification and exergy matching are the keys.

One of these systems also destroys far more exergy than the other.
Choose wisely.
The 133,000 MW of planned U.S. gas plants overlook several major financial risks. Meanwhile, the costs of wind and solar, paired with battery storage, are not tracking the rapid climb of gas prices and they have no fuel costs.

Increasing clean energy abundance is the key, but making the energy system more efficient is the lever.
We do that in two ways:
1. Electrify as much as possible.
2. Exergy matching.

Amen. The way to address climate or energy is not to police consumption, but rather to increase clean energy abundance.

Industrial heat is one of the biggest sources of wasted exergy.
Industry uses vast amounts of high-quality energy to produce low-quality heat, destroying huge amounts of exergy in the process.
Industrial heat pumps can directly reduce this waste.

Industrial heat pumps are one of the most underrated technologies in the energy transition. They work. They scale.
And they’re finally moving from demonstration to deployment.
Here’s a 95t heat pump component just traveled l by river to reach BASF’s Ludwigshafen site.

Old way: Burn fuel at very high temperatures, then degrade that energy down to the temperature the process actually needs.
Heat pump way: Use a small amount of high-quality electricity to lift already available low-grade heat to the required temperature.
