Should nuclear power expand?

Side A · “Build more reactors”

• Nuclear plants supply steady, round-the-clock low-carbon electricity that wind and solar cannot yet provide alone.
• Newer and smaller reactor designs could bring costs and build times down, and rising power demand (including data centers) needs firm supply.
• Where critics push back hardest: recent Western projects have run years late and far over budget.

Where they actually disagree

• Shared ground: both sides accept nuclear power is very low-carbon over its lifetime.
• Disputed evidence: what new designs will really cost, and how much storage a renewables-heavy grid needs.
• Values and priorities: how to weigh waste and accident risk against the speed of cutting emissions.

Side B · “Put the money elsewhere”

• New reactors often take a decade or more to build; wind, solar, storage and grid upgrades can be added much faster.
• Each dollar spent on renewables, efficiency and grids today may cut more emissions sooner.
• Where critics push back hardest: whether batteries and flexible demand can cover long stretches without wind or sun.
