Transformations of energy usually produce some energy in the form of
heat, which spreads around by radiation or conduction into cooler places.
Although just as much total energy remains, its being spread out more evenly
means less can be done with it.

Physical Science: Conservation of energy and the increase in disorder Grades 9-12, page 180 Everything tends to become less organized and less orderly over time. Thus, in all energy transfers, the overall effect is that energy is spread out uniformly. Examples are the transfer of energy from hotter to cooler objects by conduction, radiation, or convection and the warming of our surroundings when we burn fuels. |
