What's actually happening with renewables? Hype, revolution, or both?: Nuclear advocates
The comparison nobody wants to make France generates 70 percent of its electricity from nuclear power. Grid emissions: 56 grams of CO2 per kilowatt-hour. Electricity cost: roughly 20 euro cents.... What's actually happening with renewables? Hype, revolution, or both?: Transition realists
The layering In 1900, coal provided 95 percent of commercial energy. Oil was a curiosity. Then the internal combustion engine arrived. Within fifty years, oil dominated transportation. Coal was finished, right? Global coal consumption in 2023: 8.5 billion tonnes. Highest ever.... What's actually happening with renewables? Hype, revolution, or both?: Grid realists
6:47 PM At 6:47 PM on September 8, 2020, the California Independent System Operator ordered rolling blackouts. Temperatures above 110 degrees. Air conditioners at maximum. The sun was setting. Solar dropping toward zero. Wind negligible. Two million people lost power.... What's actually happening with renewables? Hype, revolution, or both?: Renewable advocates
The verdict on the projections In 2010, the IEA projected 26 gigawatts of solar by 2020. The world installed 135. By 2023, annual installations hit 420 gigawatts — a number the 2015 models did not expect until after 2040.... What's actually happening with renewables? Hype, revolution, or both?: The Story
The cheapest electricity in history In 2024, a solar panel cost less per kilowatt-hour than a coal plant in every major economy on Earth. The International Energy Agency, which had underestimated solar deployment every single year for fifteen consecutive years, called solar "the... Should we go all in on nuclear energy?: Portfolio pragmatists
48.7 gigawatts January 17, 2024. London, minus four Celsius. Sun set three hours earlier. Wind: 2 percent of installed capacity. Demand: 48.7 gigawatts. Gas turbines flat out. Nuclear at full output. Emergency demand response activated.... - Venezuela only has a window of opportunity of maybe 5 to 10 years to make money off its oil. Solar and battery technology is catching up fast, and if the country waits too long, its oil resources will no longer be worth much. It will need every cent it can get to repair its economy.The status quo of continued sanctions and embargoes would mean missing this window of opportunity entirely. It would be quite tragic for a country to have had a devastating fight with its close neighbour over a resource that has such a limited shelf life only to end up with nothing.Crucially, this means the government and investors must be incredibly disciplined. They should only invest as much capital as can generate a full return on investment within this short timeframe. Sinking billions into long-term infrastructure that takes decades to pay off would be a secondary disaster if global demand disappears before the debt is cleared.Venezuela needs to be forward-thinking and prepare for the day the oil is not worth extracting. On the bright side, the country will be free from its resource curse one way or another within the decade.Against that backdrop, a final question seems unavoidable: when people call for Venezuelans to rise up against the invasion, are they genuinely acting in the interests of Venezuelans, or are they mainly expressing their own tribal or ideological instincts?
This is a thoughtful analysis, but I think there is a missing layer that changes how we answer the final question. First, when we talk about renewable energy, we need to be honest about what it is made of.... What cool new technologies are you seeing emerge? How do we know we can trust them? Curious about all, but I'd especially love to see non-AI versions, like:
- New batteries for solar: storing heat in big piles of dirt
- A while back Tommy mentioned cowfart backpacks
- Maybe it's something old for you, but we're not in your field so we don't know about it yet
Even though a lot of what we share won't make it, for a variety of reasons, I always find get an overview of the cool stuff humans are creating really inspiring and hopeful.
super, this is really great to hear! an acquaintance of mine drilled a geothermal well for his house in East Austin about a decade ago. It was hard to find the people for it and he kinda had to DIY it— I bet there's a good business opportunity here with lots of positive... What cool new technologies are you seeing emerge?

IIRC the Ocean Cleanup Project has begun operating and is actually pulling quite a bit of plastic out, scaling up. It's not exactly new tech, but it's encouraging. They might actually clean up the Pacific Garbage Patch within several years.... Finally they learned to cut off people's mics. Hot take: If the media wasn’t so Green and did this in 2016, I think Hillary would have won.
Yeah for a couple of decades I’ve felt like we’ve been missing a "moonshot" to rally behind, and that that moonshot should be not just renewable energy cheaper than oil/gas, but free or positive sum energy....
