#Energy rule #1 The energy system is complex & connected. Diverse sources, processes, & uses - issues of economics, science & tech., environment, culture & politics, security, access & equity & much more are all connected. Beware of simple, silver bullet, "just do this" answers.

It is amazing how little most people know about the basics of oil in the United States. A few fundamentals for the interested. 1. Oil production in the U.S. is at record levels (still slightly below pre-pandemic levels)

8. The transition away from oil is underway. In June 2023, the International Energy Agency announced that it expected the use of oil for transport fuels to decline after 2026 (because of EVs, biofuels, & efficiency) with peak oil demand in 2028-2030. iea.org/news/growth-in-globa…

7. The U.S. continues to import "heavy" crude oil for refining because it has significant infrastructure (esp. "cokers") to "break" long-chain hydrocarbons. Thus, the U.S. imports heavy crude, refines it, and exports finished petroleum products.
68
6. Only about one-quarter of U.S. oil production occurs on federal/public lands, most of it offshore. However, onshore oil production on federal lands has tripled in the last decade.

5. The U.S. is a net exporter of oil. In 2005 & 2006, the U.S. net importer (60% of the volume of petroleum products provided to consumers) while in 2022 it was a net exporter (6% of the volume of petroleum products provided to consumers).

4. Note the difference in numbers between the first and second graphs. Reason? The U.S. gets a lot of oil from natural gas production. Natural gas comes out of the ground "wet" with "Natural Gas Liquids" which are separated and added to the flows of crude oil to refineries.
64
3. The U.S. is the largest oil producer in the world, well ahead of Saudi Arabia and Russia. Again, note the increase after 2008 because of fracking.

2. The reason for the sharp increase in production around 2008? Fracking. Fracking utilizes two technologies (hydraulic fracturing and horizontal drilling) which were decades in development. nesfircroft.com/resources/bl…

Attention Montgomery County voters, the Democratic Central Committee may be “downballot” but please vote for Andrew. I may be biased, but if you know him, you know what a great person he is and how devoted to making our community a wonderful place to live for everyone.

So, my lovelies, I just dropped Version 4 of the Clean Hydrogen Ladder! For anyone new to all this, the ladder is my attempt to put use cases for clean hydrogen into some sort of merit order, because not all use cases are equally likely to succeed. 1/10

The Russian Supreme Court has banned Memorial, the organization dedicated to writing the true history of the Soviet union. It's an extremely bad omen. theatlantic.com/ideas/archiv…

Annual growth in fossil CO₂ emissions (black dot) can be decomposed into: ↗ Population: constant growth ↗ GDP/Population: grows except in crises ↘ Energy/GDP: Efficiency & structural change ↘ CO₂/Energy: More renewables, 🤓Do we see an emerging signal in the last decade?

NY has one big advantage for new transmission: it doesn't need to get permission from another state to move power from Canada down to a major population center.

It’s here - @BloombergNEF 2021 lithium-ion battery price survey. Despite battery metals ⬆️, batteries themselves continue their downward trend to $132 per kilowatt-hour (from $1,220/kWh in 2010). Outstanding work from @JamesTFrith and team

One way to look at current gasoline prices: After factoring in changes in inflation, incomes and fuel economy, the cost of operating a car is lower today than it's been for much of the last 15 years (though obviously higher than last year): energyathaas.wordpress.com/2… by @BorensteinS
