The cost of solar panels is plummeting, and this will flood the power grid with cheap electricity. But that’s just Act 1. We won’t stop building solar at the limits of the grid - we’ll build a lot more. This post explains why we'll keep building more,

There are three ways to decarbonise flying. The world's existing fleet of planes is huge, and can only run on jet fuel. Therefore, we need a drop-in fuel replacement that doesn’t cause warming. This is called Sustainable Aviation Fuel (SAF). This piece is a concentrated onboarding guide to SAF.

The basics.

Ammonia is a more expensive form of hydrogen, that happens to be better suited for transport over long distances. It’s also the only reason that 8 billion people can be alive at once (it makes fertiliser).

Hydrogen is important because it is a critical ingredient in most green fuels. Hydrogen is also the dominant cost in other clean fuels. It is not possible to produce cheap green ammonia or Sustainable Aviation Fuel without cheap hydrogen. Steel, shipping, aviation, and chemicals will need a lot of hydrogen

People are starting to take geoengineering seriously.

The four batteries of the energy transition.

In the future, we will look back on 2020 as the year that decarbonisation started.
