Potential energy
The higher an object is off the ground, the more gravitational potential energy it has. This is because the object has the potential to do work due to its height above the ground.
A basketball is an object that is fat and round and bounces off the ground.
When an object is lifted 6 feet off the ground, its potential energy is a certain value based on its height and mass. If the same object is then lifted 12 feet off the ground, its potential energy will be doubled compared to when it was lifted 6 feet. This is because potential energy is directly proportional to the height to which the object is lifted.
Wind turbine blades can reach heights of 200 feet or more off the ground, depending on the size of the turbine. This height allows the blades to capture higher wind speeds for more efficient energy production.
An object has the most gravitational potential energy at its highest point, such as when it is lifted off the ground. This is because the gravitational potential energy of an object is directly proportional to its height above a reference point, usually the ground level.

"Off the ground" is a prepositional phrase, consisting of the preposition "off", the article "the" and the noun "ground". It could be used as the subject of a sentence (Off the ground is the best place to store your food on a camping trip), a modifier (The boat was hanging off the ground), or the adverb describing action (Keep your feet off the ground).

3 times the original potential energy
A catapult is probably more effective, though a pulley is easier and safer to use.
Windmills are generally located on higher elevations or mounds in an attempt to better capture the wind. The higher the windmill is constructed off the ground, the more wind can be caught to turn the blades and thus create energy.
The potential energy of an object can be calculated using the simple formula Potential Energy = mass*acceleration due to gravity*distance above ground. For simplification, we can call the mass m and the acceleration g. Using these values, the object will have a potential energy of 12m*g when it is 12 feet off the ground. When it is 24 feet off the ground, it will have an energy of 24*m*g. This is nothing more than twice the value we calculated before, so we can say that the object's potential energy at 24 feet is twice its potential energy at 12 feet. In order to give an exact value, we would need to know the mass of the object as well.
