There are always losses in using energy. Some examples:
1. A car engine uses only 30-40 percent of the energy in the gasoline, the rest is rejected in the radiator and the exhaust
2. An electric motor is better at using most of the electric power supplied, but still loses some energy in heating of the motor windings and in friction of the bearings
3. Boiling an electric kettle-you might think that all the electric power is used to heat the water, but some must be lost from the outside of the kettle to the surrounding air.
Generally machines always lose some heat which is not usefully used, by thermal losses to the environment or by internal friction

Something hot has more energy than something cold because temperature is a measure of the average kinetic energy of particles in a substance. Higher temperatures correspond to higher kinetic energy levels.
Yes, a small object can have more thermal energy than a larger object if it has a higher temperature. Thermal energy is directly proportional to temperature, so even though the larger object has more mass, the smaller object could have a higher temperature and therefore more thermal energy.
No known plane radiates more energy than the sun. The sun is the most significant source of energy in our solar system, emitting intense heat and light through nuclear fusion reactions in its core. Even the most powerful man-made aircraft does not come close to matching the energy output of the sun.
No, according to the law of conservation of energy, energy cannot be created or destroyed. Therefore, it is not possible to get more energy out of a machine than is put into it. Any energy output will always be equal to or less than the energy input.
Low energy typically refers to a state of feeling physically or mentally tired, sluggish, or lacking motivation. It can be caused by factors such as lack of sleep, poor diet, stress, or medical conditions. Addressing the underlying cause can help increase energy levels.

No.
It could just be because she is younger than you.
A top footballer needs more energy in their diet than we do because they play football all the time and train everyday, so they are more active than us. The energy comes from the fat in the food.
Yes, a small object can have more thermal energy than a larger object if it has a higher temperature. Thermal energy is directly proportional to temperature, so even though the larger object has more mass, the smaller object could have a higher temperature and therefore more thermal energy.
because that means less energy is used. if something is more efficient than something else it is so because it can either use less energy to do the same thing or the same amount of energy to do more
More nuclei of more atoms than you started out with, less mass than you started with, and some energy.
well considering kinetic energy is the energy something has when it is moving than i would say cold because it runs more and drips faster
No. It's just another untapped resource that we should be using.
Other planets have more or less gravity than Earth, so the energy needed to move things around is also more or less.
No because when you eat something slowly, in this case its a apple, it doesn't take that much energy to eat and the more energy you have the more calories you lose
