A kettle uses electrical energy and converts it into heat energy.
Most types of energy can be converted into other types of energy.
Useful energy is energy that can be converted to any other type of energy. Wasted energy is no longer available to be converted - usually because it got spread out too much, or because it got converted to heat. Heat can be partially, but not completely, converted to other types of energy.
There are six kinds of energy. Each of these types can be easily converted into any other type of energy.
because there are to types of energy. one type is the force of and the motion
Heat. In fact you can convert part of the heat into other types of energy, only if there is a heat difference between two objects - but you can never convert all heat into other types of energy.

Sometimes it can, sometimes not. It depends, to a great extent, on the type of energy. Heat energy can only be converted partially into other types of energy; there are irreversible processes in the Universe, and converting other types of energy into heat energy is one of them.

In any energy transformation, energy of one type is transformed into some other type. If an energy of type "A" gets reduced, than another energy, of type "B", will be increased by the same amount. Or, if several types of energy get converted, or more commonly, the energy gets converted into several types, the total increase in some type(s) of energy will be equal to the total reduction of other type(s). To put it into a simple formula, the sum of all energy changes is zero (algebraic sum, i.e., considering an increase as positive, and a decrease as negative).

Or, if several types of energy get converted, or more commonly, the energy gets converted into several types, the total increase in some type(s) of energy will be equal to the total reduction of other type(s).

electrical energy
The kettle uses heat energy. Depending on your type of stove, that heat will usually come from chemical energy (in a gas stove), or electrical energy (in an electrical stove).
Radiant electromagnetic energy is converted into chemical energy in photosynthesis,
