Uncontrolled systems always evolve toward more stable states--that is, toward more uniform energy distribution (e.g., water flows downhill, objects hotter than their surrounding environment cool down).

RG127002	In a windmill, 100% of the kinetic energy from the wind cannot be converted into electrical energy because a small amount of energy will always be converted into thermal energy and transferred to the environment, during each transfer and transformation of energy.
RG170002	Which energy flow diagram represents the flow of energy when a wind-up car is wound and then let go?

Items associated with this NGSS statement in this project (ASPECt) and other key ideas
RG078003	Each time a person used a flashlight some of the energy from the battery was transferred to the surrounding environment. Eventually all of the energy became uniformly distributed in the surrounding environment and was no longer available to make the flashlight work.
RG162002	When a wind-up toy car is wound up and then let go, energy is concentrated as the spring is wound up and then becomes less concentrated as energy is transferred to the surrounding environment.
