What are some good metaphors for family? Things such as: Family is a tree Faimly is a quilt What do you think would be a good metaphor for a somewhat more disfunctional family, and how would it apply?
When electricity is generated from flowing water, this is called hydroelectric energy, and the prefix 'hydro' refers to water. Hydroelectric energy is considered a renewable energy resource because it's an energy resource that regenerates in a short time period. You can think of this like the hair on your head.
Hydroelectric energy is potential energy that is converted to kinetic energy through the forces of gravitation, which again comes from solar energy, driving the water cycle around. To answer the question, hydroelectric energy is the result of heat energy from the sun and the gravitational forces from the earth.
