Electrical energy will always create heat because there will always be some component of resistance in any circuit - though it is often considered as negligable.
Electrons "bump into" atom nuclei in the conductive material, transferring some amount of kinetic energy to them. Temperature is fundamentally a measure of atomic kinetic energy. So as a material's resistance increases, for a set current, the amount of "bumps" increase and so the material will get hotter.
In theory; any material can conduct electricity given enough voltage, but materials which we refer to as insulators would need an extremely high voltage and would be destroyed after conducting only a short burst of current.
I hope this answers your question.

What do electricity and heat have in common?
Yes. These both are the different forms of energy (heat energy , electrical energy).These can be converted one to another as per the conservation of energy- " Energy canneither be created nor be destroyed but we can convert one form to another. "Example:1.In thermal power plants, the heat energy is converted into electrical energy.2.In Electric heater, the electrical energy is converted into the heat energy. They can both be used to transfer energy, electricity through a wire or similar conductive material, and heat by conducting through a metal or grill. They can be changed one into the other. For instance, electricity passed through something with high resistance creates heat, whilst heat can be used to make steam and power turbines which make electricity.
Can Solar energy be directly converted into electricity and with what?
Method 1 PV Cells - Converts solar energy in electrical energy DC power Solar Inverter - converts DC power to AC power Method 2 Solar is used to heat liquid and convert to vapour. Vapour is used to run the turbine. Electrical generator converts mechanical energy in turbine to electrical energy.
What is a braking resistor?
A braking resistor is used in motion systems where a motor in controlled by a drive. Typically, these are high-speed servomotors controlled by a servodrive. When accelerating, electrical energy is converted to a mechanical force to move a mass. When decelerating, that kinetic energy is converted (via the motor) back into electrical energy, and must go somewhere. To brake quick enough, the energy must be dumped into a power resistor, to be dissipated as heat. Read more at the link provided below.
What energy transformation in hydroelectric power plant?
Potential energy of the water in the reservoir changes to kinetic energy as it is forced through the turbine. The blades of turbine represent mechanical energy, spinning the turbine generator which converts the mechanical energy into electrical energy due to the nature of the generator.Generators use electromagnetic induction turbines, which at its basic level is rotating a wire within a magnetic field, this generating electricity.Source(s):Engineering geologist
