Climate, Energy & Abundance
Explore the searchable directory, try Stumble, or suggest a find. Every submission requires editorial review before publication. The category hubs and collections are reading guides. There is no email newsletter or promised delivery schedule.
Solar, batteries, nuclear, the grid, and the build-more-stuff Abundance agenda — the finds where the case for optimism is easiest to make honestly.
This is our steadiest optimism anchor, and it is not denial. The climate crisis is real, the risks are serious, and the work is nowhere near finished. At the same time, clean energy is getting dramatically cheaper and deploying faster than most forecasts predicted, and a growing movement wants to make it far easier to build the good things. We hold both truths at once. This hub gathers the tools, projects, and companies working the energy transition, plus plain-language guides to the ideas behind them.

Optimism that holds both truths
The fastest way to lose trust on climate is to pick one half of the story. Doom insists progress is fake; boosterism insists the problem is solved. Neither is honest. Our standard is simpler and harder: name the real danger and the real progress in the same breath, and cite the numbers.
- Real risk. Warming is already causing harm, emissions are still rising globally, and the transition has to move faster than it currently is. We never wave that away.
- Real progress. Solar and battery costs have fallen by roughly an order of magnitude over the past decade or so, deployment is breaking records year after year, and clean power is now the cheapest new electricity in most of the world. That is measurable, not a mood.
The full argument, with sources and caveats intact: climate optimism that isn't denial, and the wider stance in The Case for Optimism.
Start with these guides
If you want the ideas before the tools, these plain-language reads are the on-ramp. They are grounded and sourced, and they keep the caveats where they belong.
- The clean-energy projects making the future look bright — our anchor piece on the solar, battery, nuclear, and grid work that is genuinely bending the trend line, with honest notes on what is proven and what is still early.
- The Abundance agenda, explained — what people actually mean by "Abundance," without the wonk speak: the view that a lot of our problems come from artificial scarcity, and that we should make it easier to build.
- Energy progress in plain language — solar, batteries, and nuclear translated into cost and deployment curves anyone can follow. Is clean energy actually winning, or is that spin?
- Climate optimism that isn't denial — how to stay hopeful about climate without ignoring the crisis. The line we care about most, spelled out.
- Startups worth watching in energy and grid — a curated watchlist with honest "early / unproven" staging and no financial claims. Who is actually building the next-generation grid.
- Climate progress you probably missed — a dated recap of real milestones the feed skipped, sourced to actual events rather than vibes.
What lives in this hub
The directory entries under Climate span the whole build-out, not just panels on roofs. Each one carries an honest "what it is / who it's for / when to use it" note and a date. Broadly, expect:
| Area | What is in it |
|---|---|
| Generation | Solar, wind, and next-generation nuclear — the fission and fusion projects trying to make clean, firm power routine. |
| Storage & grid | Batteries, long-duration storage, and the software and hardware modernizing an aging grid to carry more clean power. |
| Build & abundance | Tools and projects aimed at the bottleneck itself: permitting, housing, transmission, and the capacity to build faster. |
| Industry & heat | Cleaner steel, cement, and industrial heat — the harder-to-abate sectors where progress is quieter but real. |
| Carbon & measurement | Carbon removal, monitoring, and the open datasets and dashboards that let builders track progress honestly. |
| Adaptation | Tools that help communities cope with the warming already locked in — because optimism includes preparing, not just hoping. |

Browse by stage of the future
Not every promising thing is ready today, and pretending otherwise is how hype starts. So we also sort finds by how far along they are, from early ideas to proven deployment. Pick the risk level you are here for.
- Emerging — early and unproven, but credible: the projects to watch, not yet to bet the roadmap on.
- Building — past the demo, shipping to real users or sites, still scaling.
- Frontier — ambitious, high-uncertainty bets like fusion and novel storage, where the payoff is huge and the timeline is honest.
- Proven — deployed at scale and working today: the parts of the transition that are no longer a gamble.
Every entry in the directory carries one of those four labels, dated, so you can tell a promising prototype from a working deployment at a glance.

- Robotics, Space & Hard Tech — the tangible build-out next door: manufacturing, materials, and launch.
- Solar, battery, and nuclear progress in plain language — plain definitions for learning curves, capacity factors, and the rest of the vocabulary used here.
Who this is for
This hub is for builders working on energy, climate, or infrastructure who want a trustworthy shortlist of what is real and rising. It is for investors and operators scanning for signal above the noise. And it is for optimism-seeking readers who are tired of the doom loop and want reasons for hope on climate that can survive a second look. You do not need to be a wonk or an engineer — just curious about the future being built.
Plain-language summary
Clean energy is winning on cost faster than most people realize, and there is a growing push to make it easier to build more of the good things. That does not mean the climate problem is solved — it is not, and the risks are serious. This hub collects the tools, projects, and companies doing the work, plus honest guides to the ideas behind them, so you can find what is genuinely worth your attention without either the doom or the hype.
