Energy cannot be created or destroyed. it can only be transferred from one form to another. energy that is "wasted," does not disappear. instead, it is transferred to its surroundings and spreads out so much that it becomes difficult to do anything useful with it. incandescent light bulbs are very inefficient in energy transfer. energy-saving lightbulbs, such as fluorescent bulbs transfer a greater proportion of electrical energy as light energy. in fluorescent bulbs what kind of energy is "wasted" in the energy transfer from electricity to light?
