The electric grid is a network of power lines and other infrastructure that moves electricity from power plants to our homes and businesses—and its design affects our options for building a clean energy system.

Wildfires are becoming more frequent and severe as a result of climate change, as forests in arid parts of the world become hotter and drier.

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

Carbon pricing is a policy tool to lower emissions of carbon dioxide and other greenhouse gases, by putting a tax or other price on them.

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

Renewable energy is energy from sources, like wind, solar, and hydropower, that we cannot run out of.
