HST uses no fuel at all - it was designed to be an orbital repair satellite from the beginning, and the Shuttle that performs each Servicing Mission boosts it back into a higher orbit after they're done working on it. All power comes from the huge twin solar panels on each side. Since no more missions are planned (don't hold your breath - HST is NASA's largest PR cash cow), HST will eventually decay until it burns up in the atmosphere.
The short answer ---> Power is generated by Solar panels, saved in batteries and used as needed.

Nuclear energy.
Solar cells
Batteries will die. Generators will run out of fuel. Both of these are heavier than solar arrays anyway. Solar arrays convert energy from the sun.
The Hubble Space Telescope collects solar radiation by means of large solar panels covered with photovoltaic cells, and derives its electric power that way, which is used to operate it, warm and cool it, and run its communications systems. It's controlled from Earth, and sends its images and other data to Earth, by means of radio. It's completely uninhabited, and is in a gravitational orbit of the Earth so it needs no propulsion.
Once an object is moving in space, no fuel is needed tokeep it going, only to change its speed or direction.
You will travel in the same direction, at the same speed for eternity unless your vehicle is acted upon by some other force such as gravity or an atmosphere (Newton's Second Law). There is no air in space, and therefore no friction to slow the vehicle down and without fuel, you cannot change the direction.
I cannot think of a telescope without mirrors, unless it is completely run by computer with digital imaging.

Stars will appear to twinkle for as long as Earth has an atmosphere, because it's the atmosphere that causes the effect. From space, they're a steady light. This is why we have the Hubble telescope in orbit. Less atmospheric inteference = more accurate images. The stars themselves will stop emitting light when they run out of fuel to burn. That will in most cases be several billion years.
A spaceship runs on fuel
roll down the window and look for a gas station if you run out of fuel

Cars have Internal Combustion Engines. You cannot use rocket fuel in this type engine.At this point there is only one car that can run on rocket fuel. NASA has an experimental BMW sedan that can run on liquid hydrogen, better known as the rocket fuel used in the space shuttles...
yes, a spaceship can run out of fuel.

earth will run out of space tommorow i promise
a normal telescope can be projected further then a space telescope because it is bigger and more of it a space telescope in in space which lets it see further into space and is more exspensive to make ect
