Zalman makes a very energy efficient computer case.
HP StorageWorks drives are created to be energy efficient.

Devon Energy Tower - Houston - was created in 1978.
A diver standing at the top of a tower has potential energy due to their position above the ground. This potential energy can be converted into kinetic energy as the diver jumps off the tower.
I have not ever seen a table lamp that only requires a energy effcient light bulb. Usually all lamps will accept any light bulb regardless or energy wattage or usuage.
In a drop tower, potential energy is converted into kinetic energy as the object falls. When the object reaches the bottom of the tower, the kinetic energy is maximum and the potential energy is minimum. Some energy is also lost as heat and sound during the fall.
they have a huge tower where big solar panels reflect sunlight into the tower and the tower makes that sunlight into energy to almost 500,000 homes

I am pretty sure that it is gravitational potential energy.
