Because iron has no more excess binding energy left to release. Iron fusion consumes energy, it does not generate it.

What is massive body of plasma that shines due to energy released by nuclear fusion?
The sun and other stars.
During nuclear fusion what do stars produce?
In nuclear physics and nuclear chemistry, nuclear fusionis the process by which multiple like-charged atomic nuclei join together to form a heavier nucleus. It is accompanied by the release or absorption of energy.
Can planets generate nuclear fusion?
No. That's precisely the main difference between planets and stars - that stars can have nuclear fusion, planets not.
How often is energy released during nuclear fusion?
The only fusion energy in the universe is in the stars like the sun, and there are millions of such stars!
Do fusion reactions provide nuclear power?
No, a fission reaction is not necessary to trigger a fusion reaction, but for us on earth, it is. In the field of nuclear weapons, a fission bomb is needed to create the heat necessary to set off a fusion weapon. We have to use fission, or, rather, the energy created by that, to initiate the fusion reaction. It might be possible to use a high power source, like a laser, on a small amount of material to get fusion to occur. But we are still experimenting with this in the Tokamak, and it's far from being a done deal. Stars are, in general, massive nuclear fusion reactors. Their constant consumption of fuel powering their high rate of fusion creates a massive amount of energy, and the stars' huge gravity keeps this process from blowing the whole thing apart. No fission is needed to sustain this reaction.
Massive stars cannot generate energy through iron fusion because?
No energy is gained when fusing iron into heavier elements. Heavier elements have a higher potential energy (nuclear energy) than iron.
What is massive body of plasma that shines due to energy released by nuclear fusion?
The sun and other stars.
How do star use energy?
Stars fuse hydrogen through nuclear fusion into helium and release the massive resulting energy into space.
Why all-stars have light?
Stars undergo nuclear fusion in their cores, and so generate energy; i.e., light and heat. No nuclear fusion, no energy generation, ergo not a star at all. Generating light and heat is how we can tell a very large planet from a star. If it isn't generating energy from nuclear fusion, then it isn't a star.

Where do stars get energy?
Fusion
The element that burns as fuel in star?
The energy in stars comes from nuclear fusion. Hydrogen atoms are continually fused together to created helium and with it, massive amounts of energy.
What is the process by which stars burn brightly?
Stars get their energy from nuclear fusion - mainly, hydrogen to helium.Stars get their energy from nuclear fusion - mainly, hydrogen to helium.Stars get their energy from nuclear fusion - mainly, hydrogen to helium.Stars get their energy from nuclear fusion - mainly, hydrogen to helium.
What energy does the sun and stars produce?
the energy sun and stars produce is fusion.
Does nuclear fusion in massive stars create heavy elements?
yes
How do stars get their energy?
