There’s a lot on the agenda this week, but I’m especially excited to talk about electricity breakthroughs. By 2050, the world will need nearly three times as much power as we use today—and if we’re going to decarbonize the economy, we’ll have to electrify a lot of things that currently use fossil fuels. That means we need to deliver a huge amount of energy in a clean, reliable, and affordable way.

If you’re an electricity nerd like me, this is an exciting moment. Earlier this month, TerraPower—the next-generation nuclear power company I created in 2008—received federal approval to start building the nuclear reactor at its Kemmerer, Wyoming plant. Wind and solar are reportedly generating more electricity than fossil fuels in the EU for the first time. We’re seeing a clear shift as the world’s electricity system is becoming more diverse, more innovative, and more dynamic than ever before.

Geothermal

Geothermal power has been around for more than a century, but new approaches are unlocking greater potential for the technology. Most geothermal power plants today are located near the boundary between two tectonic plates, where you don’t have to drill as deep to find usable heat that can be pumped to the surface to turn a turbine and generate electricity.

Fusion

Fusion is the reaction that powers the sun and stars, and it has the potential to be a virtually unlimited source of clean, safe electricity. Once the technology is fully commercialized within the next decade, it can be built anywhere, scaled up, and used to make huge amounts of electricity with no carbon emissions and minimal waste.

This is an unusual technology to talk about because it’s hard to predict a timeline. It could take decades before geologic hydrogen becomes commercially viable at scale
