Dear Amy: What can energy do? — Branda, Brooklyn, N.Y.
Dear Branda: The word “energy” has been in the news a lot lately, since people are becoming more concerned about how much energy we use and about finding more energy-efficient methods of transportation and powering businesses and homes. One of the ways we can save energy is to use less electricity at home by turning off lights when we leave a room and unplugging appliances when they are not in use. This is an example of conserving electrical energy, which is just one of many types of energy.
All the different forms of energy can be categorized as potential or kinetic energy. Potential energy is stored energy and energy of position, whereas kinetic energy is the energy of motion. Energy can convert between different forms, too. For example, gasoline has chemical energy, a type of potential energy. When gasoline burns, the chemical energy is converted into thermal energy, or heat, a type of kinetic energy.
