  1. Our readingDesalination for drinking and household water is cheap and uses less energy than commonly assumed.

    Their wordsSupplying drinking and household water through desalination is really quite cheap, and uses far less energy than I’d have guessed.

  3. Our readingBritain has a systemic problem building large infrastructure projects, including reservoirs

    Their wordsI think Britain has a real problem with building almost anything, from train lines to houses, and reservoirs to energy infrastructure.

  5. Our readingQuoted subsidy totals for meat and fossil fuels mostly describe unpriced damage, not money any government could take back and spend elsewhere.

    Their wordsAgain, you cannot pay for the externalities by pulling subsidies (there is nothing there to pull

  7. Our readingMaking food more expensive is not a way to fix the food system, because higher food prices fall hardest on the poorest people.

    Their wordsSimply making fossil fuels more expensive without having affordable alternatives just makes energy more expensive, which hits the poorest hardest.

  9. Our readingCheap clean energy has broken the old trade-off between raising living standards and cutting environmental harm.

    Their wordsThe rapid drop in renewable energy costs in the last decade (alongside huge improvements in battery technologies) has started to break this deadlock.

  11. Our readingTariffs on Chinese clean energy reduce the total number of clean-energy jobs, because most of those jobs are in deployment rather than manufacturing.

    Their wordsThat’s because most clean energy jobs are in deployment and maintenance rather than manufacturing, and since higher costs slow down the rollout of renewables, increasing prices reduces the total number of people working in clean energy (even if the number working in manufacturing increases).

  13. Our readingHigh electricity prices are what is killing European industrial competitiveness.

    Their wordsAnother factor that is killing Europe’s competitiveness — not just for batteries but for many industrial products — is the high electricity costs.

  15. Our readingForced labour in Chinese clean-energy supply chains is real, and it is not why the goods are cheap.

    Their wordsBut my point is that this is still not the reason (or is only a very small reason) why these goods from China are cheaper than elsewhere. The main driver of lower labour costs has been automation; not having a human worker at all.

  17. Our readingConcerns about the energy cost of an individual LLM prompt are no longer credible, though the environmental impact of the AI datacenter buildout remains a real worry.

    Their wordsUnless you’re an extreme power user, asking AI questions every day is still a rounding error on your total electricity footprint.

  19. Our readingVertical farming swaps a land problem for an energy problem, and the energy cost is what stops it feeding the world.

    Their wordsWhat stands in the way is energy demand. Growing crops indoors is energy-intensive. So we’re really swapping a land problem for an energy one.

  21. Our readingCereals will stay an outdoor crop, because the energy to grow them indoors costs far more than the grain is worth.

    Their wordsWithout some crazy technological breakthrough, cereals are are going to be an outdoor-only crop for a long time.

  23. Our readingBiofuels cannot supply enough energy to matter for a country like Britain or to replace all transport fuels.

    Their wordsThe US uses a UK-sized amount of land to grow biofuels.4 In return, it accounts for around 10% of the country’s motor gasoline supply.
