It depends on what fuel or power is used to generate the electricity .
Nuclear or atomic reactors are a way to create electrical energy. If they are run properly, they do not pollute the air like coal plants.
It does not pollute and is cheap.
Electrical energy can be sent over long distances and distributed locally without pollution, it is very versatile in use, from heating, cooking etc to movement by motors. It does not pollute when used, but of course power stations do cause pollution, but at least they can be sited away from where people live and work.
It depends on what type of radiant energy you're talking about
Wind energy doesn't pollute the air.
Electrical energy is the energy in electricity - mainly in electrical currents.
Electrical to kinetic to electrical energy in your cells
Electrical energy can be formed by solar, wind or hydro energy. This energy is transformed into electrical energy.
The electrical energy of thermal energy is called kinetic energy. An example of electrical energy converted to thermal energy is a toaster drawing current from an electrical outlet.
electrical energy to heat energy or electrical energy into kinetic energy
Motors convert electrical energy to mechanical energy. Generators transfer mechanical energy to electrical energy.
An electrical generator generates electrical energy. It takes some kind of mechanical energy to turn the generator. The generator is said to convert mechanical energy into electrical energy.
