No energy can be used over and over again. Basically, when you use energy, at least part of it gets wasted - converted into an unusable form of energy, usually heat.
The law of conservation of energy states that energy cannot be created or destroyed, only transferred or transformed from one form to another. This means that the total amount of energy in a closed system remains constant over time.
Yes it is as it can be used over and over again and never run out
What kind of bridge cannot travel over a suspension bridge.

You cannot do that; you will need to retype what you just said, you cannot just say what you want to say over and over again, plus that will be annoying too.
Renewable energy sources such as solar, wind, hydro, and geothermal energy can be used over and over again because they are naturally replenished. These sources are sustainable and do not deplete the Earth's resources.
yesBrioPower:I have only read The Magicians Nephew and The Lion the Witch and the Wardrobe but I think that they are very good. They are the kind of books that you will want to read over and over again. I cannot speak for the others but people I have talked to like the rest of them also.
The energy from water falling over a dam is primarily potential energy that is converted into kinetic energy as it flows through turbines to generate electricity.
You cannot remove salt, so it would be best to start again.
Because you can use water over and over again to make energy.
Renewable source is one which can be used over and over again. What i mean to say is that once used, we can again use the resource. For example: Energy from sunlight. This energy from sunlight never replenishes and can be used continuously for a long period of time.
wasteful energy is energy that is niot uyse and cannot be used again, it is also unuseable to be reused. Wasteful energy is energy that is also energy that can not be use over and over, :), the way energy works is the way it works, but sine energy doesnt want to work or be reused. :O
