It’s one’s energy source itself that makes the difference in the end. From the environment to relationships, we rely on some form or energy—and all energy needs a source. It could be petroleum to drive an automobile. It could be a battery to drive something faster and simpler, but whether a battery is cleaner than gasoline depends on where the battery gets its energy.
Or, your energy could be your own source of personal power. Do you pollute those around you on account of your social energy? At the end of the day, it goes back to the source.
