Step-by-step explanation:
Radiant energy is the energy which can be harnessed from the electromagnetic radiations. These radiations are the source of thermal energy. The sunlight is the source of radiant energy as it is a source of radiations such as visible, invisible, ultraviolet and infrared. The thermal energy from the radiations of sun can be used to generate electricity through solar power plants, solar devices like streetlights, cookers, solar panel cells and others.
On the basis of the above description, radiant energy power plant uses energy directly from the sun to generate electricity.
