True.
No matter what, the energy given by a substance can act as energy for something else. For example, the energy exerted by wind can be used to power a windmill, which in turn can power a generator that creates electricity. Another example can be running water, which generates energy that is used to turn a water turbine, which then generates electricity from the energy that is passing through the turbine.
