Nuclear energy is low-carbon energy made by breaking the bonds that hold particles together inside an atom.

Aviation emissions are responsible for around 5% of climate warming, and this share is rising.

Hydrogen is the most abundant chemical substance in the universe. It can be used as a fuel that does not produce greenhouse gases when burned.

Fusion energy is the source of carbon-free energy at the center of stars, including our own sun.

Biofuel is any liquid fuel made from “biomass”—plants and other biological matter like animal waste and leftover cooking fat.
