Conservation of Energy in daily life

I am trying to come up with a good example of a common situation where conservation of energy applies. Anybody have any suggestions?

Thanks

Any particular kinds of energy? The most common would be PE <--> KE, with an example being a pendulum. Another would be ChemE <--> Heat energy, with combustion being an example.

Electrical to kinetic (+ heat): electric motor.

Cooking.

Driving a car.

Pretty much every situation where you see an energy conversion (kinda by definition) is a good example of conservation...
