    Miriam,
            You maybe should include chemical (and several kinds of nuclear) along
    with variations such as electrical, magnetic potential, gravitational
    potential, etc. in a "list".
            I think that making a "list" of all types of energies is a little
    dangerous since it gets similar to making a list of "all ethic groups in
    the world." There are many overlaps, differing ways to classify, and
    differing opinions. For example, you have included "light" and "solar" on
    your list. Why would solar and light not be the same, except ...
    "solar" is a type of "light" energy that originated in a specfic star ( our
    Sun),
    or are they different because "light" energy is only that part of the
    electromagnetic spectrum that we can detect with our eyes and the Sun gives
    off many types of electromagnetic radiation,
    or is it that the importance of sunlight to our survivial on the Earth
    causes us to give different forms of energy different names?
            Another example of this is in the case of "chemical" energy. The energy
    that is contained in a molecule of sugar and released by our bodies when
    eaten could also be classified as "electrostatic potential energy" because
    of the way in which the energy is stored in sugar molecules before it is
    released.
            Maybe a more student-friendly way is to say the energy is energy and there
    are a LOT of terms that are used to describe differences, but there is not
    15, 73 , etc. "types" of energy.

            In answer to your question about "mechanical"....It is usually used to
    describe situations where things are moving, twisted, stretched, bent,
    lifted against a force (especially gravity), etc. Mechanical is NOT the
    same as "kinetic". Kinetic refers only to an object in motion.
