At this point, if any Democrat says anything other than 'Abolish ICE and DHS', they need to be primaried and never allowed to hold public office again.

There are two major trends underway that will shape humanity's future:
1) Coordinated untangling from US-led world order for domestic & energy security.
2) Developing nations' rapid electrification & reducing import dependence.

Not only that, Texas has one of the fastest growing electricity demand in the US, thanks to a booming industrial sector including AI.
And yet, for the past three years, >90% of additional demand was met through solar, wind, and batteries, with very little growth in fossil fuels.

This is what American decline looks like. Cutting research funding and politicizing award making will only accelerate this trend.
The scary part is not that US universities are getting worse. It's that we're falling behind & China is investing a LOT more than us. www.nytimes.com/2026/01/15/u...

Data: Between 2019 to 2024, CA added 21 TWh of clean energy while TX added 83 TWh. TX did this with both a booming population & growing power demand (+84 TWh). As I showed Ketan, if TX maintained both demand & clean energy growth at current pace, it will decarbonize faster than CA.

Your original post was about electricity; I am saying TX fared better than CA from 2019-2024.
TX: +84 TWh demand; +77 TWh clean energy
CA: +13 TWh demand; +21 TWh clean energy (-9 TWh hydro)
If the rate of both demand & solar growth continue at current pace, TX will fully decarbonize before CA.

Well, for starters, you could tell your idiot boss to get rid of tariffs on electrical components and parts!

China shows what energy dominance might look like. Not only does China export more clean tech than US does fossil fuels, Chinese exports are (i) accelerating, and (ii) highly diversified across products & destinations.
This is a major warning sign for the US!

Cool study - using AI to show people car-free visuals of familiar streets helped increase support for transit-oriented policies.
What was hilarious was this description of the nightmare that is I-35 in Austin as "popular American street, the I-35 in Austin".

We are not prepared for $5 natural gas - notice how the CIs are skewed high? There's significant upward pressure on prices.
- Demand growth from datacenter +LNG
- Limited supply growth (perhaps East Texas?)
Keeping consumer prices low requires shielding them from costs to serve large loads.

We want to reframe debate around LNG.
❌ What is the carbon intensity of US LNG?
✅ What is the risk that the carbon intensity of US LNG exceeds 30 g CO2e/MJ (or other threshold)?
Buying low-carbon LNG is a risk management problem, not a supply chain assessment problem.

More shockingly, GHG intensities are highly skewed - evidence of super-emitting supply chains.
Traditional LCAs assume normally distributed risks. By including data, distributions become log-normal—highlighting significant tail risks that are otherwise invisible to deterministic LCA approaches.

Measurement informed GHG intensity is about 30% higher than inventory-only based estimates.
Based on empirical data, the US actually has lower average GHG intensity than other exporters. This is why EU #methane rules are the best thing to happen to the US #LNG industry. It forces others to measure.

Conventional lifecycle assessments (LCA) use official inventories, which underestimates emissions.
By incorporating satellite data, we find ~5x variation in GHG intensity - from <9 g CO2e/MJ in Qatar to ~40 g CO2e/MJ in Algeria.
The pink bars? Those are emissions missing from conventional LCAs.

You've heard of #methane super-emitters at oil and gas facilities.
But have you heard of super-emitting LNG supply chains?
Our latest work uses satellite data on 12 LNG exporting countries to assess their GHG intensity.

Federal policy makers, especially Dems, have a lot to learn from Texas if you want to rapidly expand clean energy.
Even a tech-neutral approach to energy infrastructure expansion will result in an overwhelming build out of clean tech because it's faster and cheaper than fossil fuels.

We have two major studies dropping next week!
1) Using satellite data on global LNG producers, we discover super-emitting supply chains!
2) We report on the first ever GHG emissions tracing from US LNG supply chains using direct measurements. With counterintuitive fundings!
Stay tuned!
