That depends on how long the 1 kW is applied. Please note that kW is a unit of power, not a unit of energy.
In general, 1 kW of electrical energy can be converted into 1 kW of heat - if used in a heater. With a heat pump, 1 kW of electrical energy can, in fact, pump several kW of heat energy.

How much thermal energy is produced in an electric motor j of electrical energy are converted into 92j of mechanical energy?
Assume no vibration loss, the amount of energy input to electric motor subtract out the converted 92 J of mechanical energy is the thermal energy produced.
Is that light energy or heat energy of solar energy is converted into the electric energy?
A photocell converts light energy (radiant electromagnetic energy to be precise) into electrical energy. A thermocouple can convert heat into electrical energy. The radiant em conversion yields much more energy than a heat conversion.
Why is there a need to reduce the loss of heat to the surroundings?
Basically, heat is a form of energy so depending on the context there will be slightly different answers. But in the case of trying to find out how much energy is produced by something, for example methane, when it combusts it produces heat energy, and some of that heat energy is lost to the surroundings, so when you then try to find the final figure for it's energy production, it will be lower and also wrong.
How much electric energy does milk have?

What type of energy is heat?
Heat is thermal energy. It is pretty much the same thing as thermal energy.
What happen to an electric current after it passes through each bulb?
There is a piece of filament in every light bulb, which has so much friction that when the electric current passes through it, heat energy is produced. This heat energy is then converted to light energy.

How much electric energy is produced from 25ibs cow dung?
It isn't clear what you mean by "ibs".

What is best energy saver heat pump orAir condation electric heat comb?
A heat pump saves much more energy. They are also a lot more expensive to purchase as an initial investment.
When radio is turned on electrical current flows through it what main type of energy is produced by the radio?
The electric power supplied to a radio is used to produce two types of energy: heat and sound. The sound is the useful part, and work is always continuing to find ways of producing less heat, because it only uses up electric power, and there are much better ways to keep our hands warm.
What is the measurement used to describe how much energy is produced or used during a chemical change?
The free energy (delta G) is the measure of the amount of energy produced or consumed in a reaction. Enthalpy (delta H) is a measure of the amount of heat produced or consumed in a reaction. These two quantities can sometimes be the same. When they are not, the other missing component where heat can be consumed or produced is work.
How much of the energy is being produced with the clean energy and how much is being produced with the non clean energy?
different resource of energy in pakistan
How are light emitting diodes able to produce so much light but without producing any heat?
The electrons in the electric circuit excite the atoms of the diode efficiently, not much energy is wasted (in the form of heat).
How much heat does a reaction produce?
The amount of heat produced in a reaction is not fixed. It depends upon the total amount of energy change that has taken place in the reaction altogether. Not only this, all reactions do not produce heat. In some cases we have to supply energy from external sources to get the reaction started.
