  1. Big tech's huge power needs and prepaid contracts are making small modular nuclear reactors financially real, giving nuclear a better shot than past revivals.
  2. AI can generate lots of creative output, but people still prefer human-made art and live presence, so human judgment and improvisation will stay valuable.
  3. With births falling, countries will face real labor shortages that humanoid robots and physical AI — paired with immigration — are likely needed to fill in-care, construction, and logistics jobs.
Slow Boring 3813 implied HN points 31 Jan 24

Unreported Truths 57 implied HN points 03 Mar 26
  1. The EPA's endangerment finding was revoked, removing a key legal basis for aggressive U.S. decarbonization, and this policy reversal drew surprisingly little public protest.
  2. Many decarbonization policies depended on expensive subsidies and immature technologies like intermittent wind and solar without cheap storage, and Europe’s energy crisis plus China’s rising coal use undermined those efforts.
  3. Political and cultural momentum for radical climate action has faded: voters rejected big green subsidy programs in 2024, legal fights over regulation will likely shift decisions to Congress, and climate activism no longer mobilizes mass protests.

  3. The publication will remain free and unpaid, produced in spare time to keep it enjoyable, with plans to continue publishing data-driven posts into 2026.
Unreported Truths 52 implied HN points 04 Mar 26
  1. Global carbon dioxide emissions have risen about 60% since 2000, so the world is emitting more CO2 now than ever.
  2. The US, EU, and Japan cut emissions roughly 25% and now make up only about one-fifth of global emissions, while China emits far more and is rapidly adding coal-fired power plants.
  3. Emphasizing Western cuts while ignoring booming emissions elsewhere weakens climate messaging and breeds skepticism, and clear charts or examples of elite hypocrisy can be persuasive to doubtful audiences.

Renewable Revolution 439 implied HN points 24 Jul 24
  1. Battery minerals are becoming more efficient and less dependent on mining. Advances in recycling and chemistry can help meet demand without exhausting resources.
  2. In the coming decades, we might reach a point where we won't need to extract new battery minerals at all. We could rely on recycling old batteries instead.
  3. Countries have a big chance to shift from fossil fuel use to sustainable energy. This change can happen faster and cheaper than many think, especially if everyone works together.
Spilled Coffee 40 implied HN points 07 Mar 26
  1. The market weakened last week with major indexes down and the S&P 500 slipping into negative territory for the year after several consecutive losing weeks.
  2. Oil surged dramatically—pushing energy to be the only sector in the green and the clear top performer year-to-date.
  3. The S&P has traded in an unusually tight range so far, but underlying sector rotation, historical mid‑March seasonality, and fresh jobs concerns increase the odds of a bigger move soon.

Gordian Knot News 769 implied HN points 04 Dec 25
  1. The Korean APR1400 nuclear reactor is much cheaper and more efficient to build compared to the American AP1000, which has become overly expensive.
  2. Westinghouse has used legal tactics to hinder the APR1400's export, claiming it involves American technology, despite the Koreans having rights to it.
  3. A recent settlement means Koreans now have to pay high licensing fees to Westinghouse, significantly increasing the cost of exporting the APR1400 and impacting the future of affordable nuclear energy.
Adetokunbo Sees 104 implied HN points 14 Feb 26
  1. The world finances destruction far more than protection: about $30 is spent harming nature for every $1 spent on nature-based solutions, funneling trillions into damaging activities.
  2. Ecosystems are being lost faster than we can restore them: roughly 15 billion trees are cut while only 5 billion are planted each year, and rivers and oceans grow more polluted despite cleanup efforts.
  3. Harmful subsidies and overconsumption make short-term profits but create massive long-term costs; cutting fossil fuel use and investing in nature-based solutions could prevent trillions in future damages.

Phillips’s Newsletter 274 implied HN points 18 Jan 26
  1. U.S. policy under Trump has weakened Ukraine’s defenses by delaying aid and limiting air-defense support, which gave Russia time to intensify strikes on energy infrastructure and worsen civilian suffering.
  2. The appointment of Mykhailo Fedorov as defense minister is widely welcomed because he’s young, tech-focused, and prioritizes air defense, drone production, and professionalizing the military to raise brigade performance and morale.
  3. Russia’s ground advances remain slow and have been slowed further by bitter cold, but its campaign of hitting power and heating is causing major civilian hardship even if it has not broken Ukrainian resistance.
Construction Physics 8977 implied HN points 23 Nov 24

Doomberg 8315 implied HN points 09 Nov 24
  1. Trump's election may negatively impact climate change efforts, as many leaders are skipping important climate meetings. It seems fewer people are interested in tackling climate issues right now.
  2. While Trump used to criticize climate agreements, his focus might now lean towards boosting American industries, even if it increases carbon emissions. He believes prioritizing local manufacturing is more important.
  3. There's a belief that Trump's return to power could shift environmental policies significantly, possibly leading to a long-term impact on climate efforts and regulations. His supporters seem to back him partly due to discontent with current environmental strategies.
Doomberg 7505 implied HN points 20 Nov 24
  1. AI's need for power is too high for current energy grids. This means we might face problems trying to meet that demand.
  2. What if new rules stopped data centers from using the main power grid? This could change how we think about energy sources.

Fields & Energy 299 implied HN points 17 Jul 24
  1. Skin depth refers to how electric current mainly flows close to the surface of a wire, especially at high frequencies. This means most of the current doesn't penetrate deep into the conductor.
  2. Litz wire is made up of many fine strands that help reduce resistance by allowing current to flow through a larger area. This is especially useful at high frequencies where skin depth is very small.
  3. Using litz wire not only reduces energy loss due to resistance but also makes wires more flexible and less likely to fail mechanically compared to solid wires.
Noahpinion 26118 implied HN points 14 May 23

Not Boring by Packy McCormick 119 implied HN points 22 Jan 26
  1. Venezuela is a massively underpriced opportunity beyond oil — if rebuilt and democratized it could join Colombia, Panama, and Ecuador as a powerful nearshoring bloc and a strategic partner to the U.S., unlocking big trade and job gains.
  2. Modern infrastructure, reliable dispatchable power (notably hydropower), and U.S.-backed financing and institutional reform are the keys to attracting hyperscale data centers, manufacturing, and long-term investment.
  3. Venezuelan entrepreneurs and an 8M-strong diaspora have already shown leapfrog innovation (e.g., Cashea), but private firms will scale up only once political and legal risks meaningfully decline.
