Electrical power. Conceptual image of power station cooling towers within a glowing light bulb. This image represents the generation of the electrical power used to power the light bulb. In this case, the energy is produced at power stations, which use the energy to boil water and produce steam, used to drive turbines that generate the electricity. The excess heat is absorbed by boiling yet more water, which is vented into cooling towers like those shown here.
