Many different types of energy can be converted into heat energy. Light, electrical, mechanical, chemical, nuclear, sound and thermal energy itself can each cause a substance to heat up by increasing the speed of its molecules.
â¢ In energy transformations, some energy is always lost to the environment as thermal energy. Examples of energy transformations and their uses: Â· A television changes electrical energy into sound and light energy. Â· A toaster changes electrical energy into thermal energy and light.
