If energy is transformed from one form to another, for example electric power to mechanical power in an electric motor, in an ideal situation there would be no losses and therefore an exact equivalent in the new form of energy. In practice there are always losses, the process is not 100 percent efficient. In the above case there will be some thermal losses due to heating in the motor windings, and some windage losses due to air resistance to the moving parts, and some frictional losses in the motor bearings.
In this case the losses should not be large. In a power plant operating the Rankine cycle converting thermal energy to electric energy (see link below) large losses are inevitable, and even in the most efficient power stations more energy is lost to the cooling plant (water or air cooling) than is turned into useful output energy.
heat
It is produced when another type of energy is converted to heat energy
Heat will usually be produced in conversion of energy because of inefficiencies.
Some energy is converted to electromagnetic (heat) energy.Related Information:This can usually be considered wasted energy, since you can't convert all of the heat back into other energy forms.
Usually some energy gets wasted, and converted into heat.

Solar energy is converted to chemical energy in the form of high energy carbohydrates, usually glucose.
Heat energy
If efficiency is 100%, each Joule of electrical energy is converted into one Joule of another type of energy.

Yes, it can be converted into another kind of Energy. Example: The chemical energy of petroleum is converted to mechanical energy in a car engine with some loss as heat and sound energy. The mechanical energy is converted to kinetic energy.
Some of the energy will usually be converted into an unusable form of energy, often as heat.
