![]() Lightning is so powerful that if we could capture the electricity in a single bolt, it could power our entire home for days. Lightning occurs when electrons are discharged from a cloud. Generators create the electricity used in our everyday lives, but other forms of electric energy occur naturally. A conductor is a material that can carry electricity, like the wiring in homes. Electrical energy is the movement of electrons through a conductor. We create electricity by forcing electrons to move from atom to atom. Atoms are made up of a nucleus, protons, and electrons. Differences in the length of the waves in this part of the spectrum cause us to see different colors.Ī huge maze of wires in every house carries electrical energy to do many different jobs, from lighting your home to cooking food.Įlectricity starts at the atomic level. Most radiant energy can't be seen, but there is a small part of the electromagnetic spectrum that is called visible light. The shorter the wave, the more energy and heat are created. The electromagnetic spectrum lists all the types of radiant energy by the length of their waves. Scientists use the electromagnetic spectrum to discuss the types of radiant energy. ![]() The sun is our major source of radiant energy because it gives off a great amount of heat and light. Radiant energy is the energy created through electromagnetic waves, such as light, heat, or radio waves. Turn the page for more information on radiant energy. Radiation is the movement of energy in the form of waves. ![]() This continues until the water is boiled. As it gets hot, it rises, and the cooler water goes to the bottom where it gets heated. For example, when you boil water, the liquid nearest the flame heats up first. Hot vehicles in the summer are a form of heat energy.Ĭonvection is the movement of hot liquids or gases.
