Why? Because people support nuclear energy in most countries:

And that support is growing:

Why so much support?

Nuclear is the best type of energy across every factor that matters: safety, environment, sustainability, reliability, politics, and economics.

Then why is it so polemic? Because understanding these aspects requires so much detail that they appear complex. In this article, you will learn all the details of why nuclear energy is the best.4 It boils down to this:

1. Safety & Health

Nuclear seems unsafe and risky because accidents appear monumental and the danger is invisible. It awakens a primeval fear in humans, like plane crashes. But when you measure actual safety, it turns out nuclear energy is among the safest sources of electricity.

Lowest Deaths per TWh

The best way to measure safety is by deaths per unit of energy (eg, deaths/TWh). What we get…
