This isn't chemistry. Its physics. Kinetic energy (water) to electric energy (dam) as the hydroelectric dam works. Then, as the current travels from the plant to your crib, electric energy to heat energy (wire resistance). Then when you are using the dryer electric energy to heat energy (hot air) and sound energy (air particles vibrate due to the heat energy).
When studying the
movement of heat, what does the term "system" refer to any quantity
of matter of fixed identity of the chosen study. “Surroundings" refer to
the rest of the universe beyond the boundary of your chosen study or system.
