THEORETICALLY......
Dark energy causes the expansion of the universe to speed up.
It makes up about two-thirds of the universe.
Since "dark energy" was not predicted by standard theories of physics, then all of our basic theories of elementary particles like electrons neutrinos and quarks, and the forces between them, are in need of a major upgrade.
Overhauling our understanding of the universe is not new.
Early theory about the light and heat process happening on the sun included a monstrously gigantic ball of flaming wood.
It wasn't until the 1920's and 30's that the applications of Quantum mechanics & physics finally took hold and brought about the Electronic Age.
So, dispair not. "Dark energy" may prove some theories wrong, but inevitably, will open up brand new technologies we haven't even begun to dream of.

If what you mean what is dark matter (I am assuming so because all matter is, is a form of energy, thus:)? Then my answer for you is that the public is not knowing what it truly is. I think that there are people out there who have hypothetical reasoning thinking what it is, or could be. To my believe, I think that it is a very dense material that defies all of the known laws of physics. It may also be called WIMPs, or Weakly Interacting Massive Particles. They are found at the heart of every galaxy, including the Milky way Galaxy. Some of the dark matter has reached a point of stability and thus quit it 'sucking' in of things. I hope that I have answered your question. If I am incorrect then I am open to corrections.

I have to add to the entries above, that the most recent quantum physics theories support the brane theory, which is the theory that our universe is a 4 dimensional brane (like a membrane) that moves in higher dimensions. The dark energy and dark matter that was proposed previously to "fill in" for missing energy and matter are no longer required to describe the universe, as the current theory is that gravity falls off in those higher dimensions in which our universe moves in, and the so called "dark matter" and "dark energy" are just a result of gravity from other branes - other universes - having an effect on the matter and energy in our universe.

Presently known amount of matter is not enough to hold the universe as it is presently. As of now there is only 4% actual mass available for gravity to hold our universe. remaining is unknown or is called "Dark Matter"
Again the dark matter does have mass but there are no atoms... which is quite difficult to imagine. And the particle is named as "nutrilino". But problem is dark matter contributes only 21% of universe. So actual mass and dark matter contributes only upto 25%
The remaining amount is in the form of energy ( not the normal energy which we know and can feel it ) This is calculated by the measuring the acceleration of the galaxy and the amount of energy required to push the universe at this rate...So the dark energy contributes to the remaining 75%.

Dark energy is a hypothetical form of energy that permeates all of space and tends to increase the rate of expansion of the universe.

The universe is expanding at an ever increasing rate. The driving force behind this is labeled dark energy today because we have no idea what it is.
