There is no fuel for a white dwarf. A white dwarf is a remnant of a star in which fusion has stopped. There is, however, quite a bit of leftover heat, so the white dwarf still glows.
A white dwarf. Basically, a red dwarf just gets cooler and cooler until it has consumed all of its hydrogen. Then it becomes a white dwarf star. It will then dissipate any remaining heat into space and eventually become a "black dwarf".
A star that has burned out and no longer has fuel to sustain nuclear fusion in its core is called a white dwarf, not a black dwarf. A white dwarf is the remnant core of a low to medium mass star after its outer layers have been ejected. Over time, a white dwarf will cool down and eventually become a black dwarf, but this process takes billions of years.
No, the sun is a main sequence star, not a white dwarf. White dwarfs are the remnants of smaller stars that have exhausted their nuclear fuel and collapsed. The sun will eventually evolve into a white dwarf in about 5 billion years.
In 5 billion years time, our Sun will turn into a white dwarf.
No, Pluto is a dwarf planet in our solar system, not a white dwarf star. White dwarfs are remnants of low to medium mass stars that have exhausted their nuclear fuel and collapsed. Pluto is too small to undergo nuclear fusion and become a star.
Yes, that is correct. A white dwarf has run out of fuel - it used it up.Yes, that is correct. A white dwarf has run out of fuel - it used it up.Yes, that is correct. A white dwarf has run out of fuel - it used it up.Yes, that is correct. A white dwarf has run out of fuel - it used it up.
No. The energy of a white dwarf is simply residual heat.
White dwarf.

No. It's a white dwarf, meaning that it has no more fuel left for such things.

A white dwarf is the core of a dead star. As the star runs out of fuel, it expands into a red giant, as the shell of the red giant became a planetary nebula, and the core shrinks and became a white dwarf.
A white dwarf doesn't run out of fuel because it no longer undergoes nuclear fusion. Instead, it gradually cools down over billions of years until it becomes a cold, dark object known as a black dwarf. This process takes an extremely long time, so no white dwarfs have had enough time to evolve into black dwarfs yet.
