Sure; please note that black holes are among the brightest objects in the Universe. For more details, do some reading about quasars. Briefly, some quasars shine as bright as a hundred galaxies - and a quasar is a black hole.
Yes, energy can escape from a black hole through Hawking radiation, which is a process where black holes emit radiation and lose mass over time. However, the escape of energy through Hawking radiation is very slow and weak in comparison to the massive gravitational pull of the black hole.
No, dark energy and black hole gravity are two separate phenomena that do not directly interact with each other. Dark energy is a theoretical form of energy that is thought to be causing the accelerated expansion of the universe, while a black hole's gravity is a result of its mass and curvature of spacetime.
Some black holes produce - or rather convert - enormous amounts of energy. A quasar, which is basically an active black hole, can radiate the energy of a hundred galaxies! Black holes can also emit a gas stream moving at nearly the speed of light. Such a gas stream can continue being emitted for thousands of years, sometimes for hundreds of thousands of years. However, controlling such energy can be quite tricky - and such an energy output can be quite variable.
When an atom is smashed in a black hole, its particles are torn apart due to the extreme gravitational forces. The subatomic particles are then absorbed into the black hole, adding to its mass and energy. The energy released during this process can contribute to the black hole's growth and power its intense gravitational pull.
a high energy black hole will have an extremely high amount of energy which they will exert from themselves. however these type of black generally have an extremely short lifespan compared to their high mass cousins which can stick around for millions of years.
Yes. The only known way to produce a black hole (although there may be others) is for a massive star to collapse, after it runs out of energy.
No. The only thing "in" a black hole is pure gravitational energy.
Particles falling into a black hole release a large amount of x-rays as they do so. This is not energy from the black hole itself, but energy release that is a sign of a black hole.
Uh...the obvious. They produce and reflect no light at all (black) and stuff goes in it (hole.)
The sun's energy has not formed a black hole.
A black hole sucks all the mass and energy which passes it, even light. So it's called black hole.

It converts it into gravitational energy.
When a star of sufficient mass stops producing energy, it will collapse into a black hole.
Such energy has a mass equivalent (m = e/c2). Any such mass falling into the balck hole will increase the mass of the black hole.
A black hole would have more thermal energy than the moon.
