It depends on what you consider to be a lot of energy. A red dwarf generates far less energy than other classes of star, but still far more than anything on Earth.
Basically, none. Red dwarf stars have a lifetime that is much larger than the age of the Universe.Actually, if a lot of additional mass falls on a red dwarf star, it would start to burn more quickly. But then, of course, it would no longer be a red dwarf star.

A white dwarf could not become a red dwarf. A white dwarf is a remnant of a dead star. A red dwarf is a star with a very low mass.
Only a red dwarf star is red. Our Sun is a yellow dwarf. A red dwarf is red because it is cool, and cool colours are red whereas hot colours are white and blue.

A star does not turn into a red dwarf. A red dwarf is simply a star that has a low mass to begin with.
There are a lot of these. They are mainly the "Red Giant" and "Red Supergiant" stars.
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 black hole is the remnant of a massive star that died in a supernova explosion. A red dwarf is nothing more than a very efficient energy user. It uses energy so slowly that a red dwarf created at the beginning of the Universe (13.7 billion years ago) is still around and will be for a few billion more years.
