All of it is the short answer, for it is all ultimately emitted as energy of a lower quality, and radiates off from the Earth. You must have noticed that the world is not getting much hotter.
Entropy is the name of this process.
Yes, friction can produce heat energy when two surfaces rub against each other, causing resistance. The kinetic energy of the moving objects is converted into thermal energy due to the frictional force generated between them.
Sound energy is produced when the water inside the kettle is heated because the boiling water releases water molecules that collide with each other, creating vibrations in the air that we hear as sound. This sound energy is considered wasted because it does not contribute to the main purpose of the kettle, which is to heat the water.
In an energy pyramid, the laws of conservation of matter and energy dictate that energy is efficiently transferred from one trophic level to another, with some energy being lost as heat at each transfer. Matter is recycled within the ecosystem, as nutrients are constantly cycled through the pyramid, ensuring that resources are not wasted but rather utilized efficiently.
Friction is a common factor that decreases efficiency by causing energy loss to the environment. When two surfaces rub against each other, heat is generated, resulting in wasted energy. Minimizing friction through lubrication or using smoother materials can help improve efficiency.
Friction produces thermal energy, also known as heat energy. This is because as objects rub against each other, the kinetic energy of their movement is converted into heat energy due to the resistance of friction between the surfaces.

Hard to say. Depends on your view of "wasted."
At each level of the energy pyramid, only about 10% of energy is passed on to the next trophic level, and the remaining 90% is typically used for metabolic processes, growth, and waste production. This is due to the second law of thermodynamics, which states that energy is lost as heat during each transfer, limiting the amount of energy available to higher trophic levels.

No they are right against each other. Face east, now turn aroud, now you are facing west.

Very few. Usually aluminum cans are used before being discarded. For example, they are filled with softdrink, then sold, and then discarded. So technically, not many aluminum cans are actually 'wasted' each year because they are 'used' in the first place.
Each year, the figure is going up substantially, with the growing international population. However, in 2006, the world as a a whole wasted over 120 billion tons of food.
