Is electricity a primary or secondary source of energy? Electricity is the flow of electrical power or charge. It is a secondary energy source because we get it from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources, which are called primary sources.

The sources of light can then be looked at in two sub categories: Natural light sources and artificial light sources. Both of these types of light sources can either come from hot sources or from cool sources. The organizer below will help you to follow this organization. Light.
3-5.PS.4 Identify the basic forms of energy (light, sound, heat, electrical, and magnetic). Recognize that energy is the ability to cause motion or create change.
In luminous objects, the input energy transforms into light energy. Common forms of input energy are chemical energy, electrical energy, nuclear energy, and thermal energy. When designing a light source, engineers consider not only the brightness, location, attractiveness, and cost of the light source.
SOURCES AND EFFECTS OF HEAT ENERGY STUDENTS’ LEARNING OUTCOMES After studying this chapter, students will be able to: þ Describe the sources and effects of heat. þ Explain thermal expansion of solids, liquids and gases. þ Explore the effects and applications of expansion and contraction of solids.
identify conventional and non-conventional sources of energy used in India; distinguish between renewable and non-renewable sources of energy; describe various types of sources of energy e.g. fossil fuels, water, wind, biomass, sea, geothermal, nuclear energy; recognise that the sun is the ultimate source of energy;
Students identify heat, light, and sound energy in different equations. Explore Students investigate the effects of increasing and decreasing heat, light, and sound energy
