try to solve the problem if possible...

Energy wasn't "released" per se - it's still contained within the event horizon, presumably.
The total mass-energy content of the universe today is of the order of the critical density,
3 x H0**2/(8*pi*G) = 5 x 10**(-30) g/cm**3,
times the volume contained within the present event horizon,
(4/3)*pi*R**3,
where R = the event horizon = c * T (speed of light * age of Universe ) = 3 x 10**10 cm/s x (2/3)*(c/H0). Here H0 is the Hubble constant, assumed to be around 50 km/s/Mpc and Omega = 1 (critical deceleration). For this value of H0, 1/H0 = (app) 20 billion years, making the current age of the Universe about 2/(3*H0) = 13 billion years, so that
R = (app.) 1.3 x 10**28 cm,
which should be equivalent to 13 billion light-years (1.3 x 10**10 y x 10**13 km/y x 10**5 cm/km).
This gives a total mass-energy mass of about 4.4 x 10**55 grams, equivalent to about 2.6*10**79 protons. The energy equivalent (E = m*c**2) of these protons is about 2.5x10**79 GeV or 2.5x10**88 eV * 1.6x10**-19 J/eV = 4x10**69 Joules.
One ton of TNT releases 4.2 x 10**9 Joules. Thus the energy equivalent of the mass=energy of the universe is about 9.5 x 10**53 Megatons of TNT. This is greater than the mass-energy of the universe, but only because the chemical process involved in exploding TNT is vastly less efficient that E = m*c**2.

the amount of energy released in big bang is equal to all the energy that exists now..it means that energy cannot be created or destroyed...

It is estimated that normal matter (that is electrons, protons and neutrons that makes up stars, planets, and us) in the entire universe is about 1.6 x10^60 kilograms.
Using E= MC^2 = (1.6x10^60)(300,000)^2
= 1.44x10^71 kilo-joules or 1.44x10^74 joules
Given that normal matter only makes up about 4% of the total energy/matter density in the universe, that means the total amount of energy/matter is about::
3.6 x 10^75 joules
PS - that's not a bad guess comparing to the amount of work that the NASA guys had went through to get their 4x10^69 joules.

The Big Bang is just a theory so it can't be solved.

0 amount of energy. The Big Bang:
God said it and bang! -- it happened (period)

None was "released"; it just changed form.
What do I know about physics?! I'm just an architect and we make the engineers do all the math ;-)

I would say a Google (googol), but that wouldn't be nice on this site.
So I say a Yahoooooo joules!

theoretically, all of the energy in the known universe.
