Energy from heaters, resistors etc. create heat energy.
It's called Ohmic heating.
As V = IR, when resistance becomes high, heat energy is created.
There is also induction heating which is a bit more complicated, using AC induction motors.
Examples of heat energy are as follows: -a bulb turned on for a long time - heat liberated from any burning object
Examples of mechanical heat energy include frictional heating produced when rubbing hands together, the heat generated when braking a car, and the heat generated from compressing air in a bicycle pump.
thermal & solar energy
Heat from burning is a chemical energy.
Heat from burning is a chemical energy.
electricity
solar energy and electric heater
The warmth of sunlight reaching the Earth is an example of heat energy. The heat produced by a campfire or a stove is another example of heat energy. The warmth generated by a person's body is also a form of heat energy.
Geothermal energy is a type of heat technology
Light, sound, and electricity are non-examples of heat. Heat is specifically related to the transfer of thermal energy between objects due to a temperature difference, whereas these examples involve other forms of energy transfer.
