Carbon cycle The carbon cycle is the complex path that carbon follows through the atmosphere, oceans, and soil; through plants and animals; and through fossil fuel formation and use.

How How solar (silicon) cells work When light hits a solar panel, an electron in a silicon atom is knocked from its orbit. This free electron is absorbed by another silicon atom … and on it goes from atom to atom creating a movement of electrons. This ‘electricity’ moves through a wire into a motor generating power to run our appliances.
