Uranium is an element found in nature. Used as a nuclear fuel, it is a source of energy. Uranium fuel is emissions-free, making it safe for the environment and in comparison to other fuels, only a tiny quantity is required to generate an equivalent amount of electricity. All the uranium produced by Cameco is used to generate electricity.
Society depends on electricity. It wakes us up, cooks our food, keeps us warm, cools us off, runs the factories, and connects us to the Internet. We may take these conveniences for granted but many of the things we do require electricity.
Electricity is a form of energy. The universe is made up of both matter and energy. Matter is all those things that have weight, or mass - rocks, trees, lakes, people, animals. Energy is harder to describe, but it is observed all the time. Energy is the force that makes things move and change. In other words, if the universe were a watch... energy would make it tick.
