How much does it cost to leave a porch light on all night?

Cost = (0.001) x (the wattage of the light) x (the number of hours it's left on) x (the cost of each kilowatt-hour of electrical energy where you live).

This is what i found on google “kinetic energy. energy is transferred from one object to another when a reaction takes place. energy comes in many forms and can be transferred from one object to another as heat, light, or motion, to name a few. this energy would be in the form of motion, with the person lifting the blue ball to a higher level.” i hope this you
