Tim Gregory
Dr Tim Gregory, nuclear chemist and author of Going Nuclear, argues nuclear power is essential for reliable decarbonization. He explains why batteries and intermittent wind/solar risk blackouts. He exposes biomass fraud and regulatory failures, compares air pollution to nuclear accidents, and links humanity’s future to high‑density energy and space expansion.

INSIGHT

Renewables Alone Can't Sustain Reliable Grids

  • Replacing fossil fuels with wind, solar, and batteries alone is physically implausible for a modern society.
  • Tim Gregory explains the UK has only ~1 hour of grid-scale battery backup and variable wind can drop to 10% of capacity, creating reliability gaps.
INSIGHT

Air Pollution Kills Far More Than Nuclear Accidents

  • Air pollution from fossil fuels and biomass causes nearly 7 million deaths annually, far exceeding fatalities from major nuclear accidents.
  • Tim compares that toll to Chernobyl, saying fossil-fuel air pollution kills roughly the same number every half hour as Chernobyl did in total.
ANECDOTE

France's Rapid Nuclear Buildout Shows It's Doable

  • France built 56 reactors between 1973 and 1999 and once generated ~80% of its power, showing rapid nuclear rollout is feasible.
  • Tim uses France's post-1970s expansion—motivated by the oil crisis—as a precedent for fast deployment.
