There is potential energy, which is non-zero if you are above ground level (or above, or below, any other reference level you choose).
No, a glass of water sitting on a table does not have potential energy. Potential energy is the energy an object has due to its position or state, such as when the glass of water is raised above the table.
The cup sitting on a table has potential energy due to its position above the ground. When lifted, work is done on the cup against gravity, storing potential energy in the cup-table system. This potential energy can be released if the cup is allowed to fall.
The cup sitting on a table has potential energy due to its position above the ground. This potential energy can be converted into kinetic energy if the cup is pushed off the table, causing it to fall and accelerate towards the ground.
The cup sitting on a table has gravitational potential energy due to its position in the Earth's gravitational field. If the cup is also filled with liquid that has thermal energy, then it would have some thermal energy as well.

The energy is chemical energy. To measure this the item could be burned in a calorimeter. Also if the peanut is sitting on a table it could have kinetic potential energy due to gravity if it fell off the table.
The potential energy of a 0.480kg bird sitting 22.8m above the ground is 107.25 joules
People can improve me, but kinetic energy is the energy of motion and particles speed of a substance. So in otherwords if you had a textbook sitting on the table, it has potential energy, but if you push it off the table it then sort of has kinetic energy.
Sitting on usually indicates you are on something, while at would be near or beside it. So if were on a table, you would be sitting on the table. If you were on a chair beside the table, you would be sitting at the table. Sitting at can also refer to a time something is happening, like: "The parliament is sitting at 2pm".

Energy can either be "potential" energy or "kinetic" energy. Potential energy is energy that is stored in some system: a stretched rubber band, a book sitting on a table, or the chemical bonds in the wax of a candle. Kinetic energy is energy that is moving, and generally comes from the release of potential energy, such as letting go of the rubber band, the book falling off the table, or lighting the candle.
An apple has potential energy when it's just sitting on a table. If you pick it up, then it has gravitational energy as gravity is pulling it down. If you bite it, it releases chemical energy to your body. And if you throw it, it now has kinetic energy. :)

Imagine a plate sitting on a table. Becasue it isn't moving, the plate has potential energy. It has energy overall because it has mass, is in an environment with gravity, and is above the ground. These three factors multiplied will give you your potential energy.
