all energy comes from the sun.

I like the Sun, I think it is totally cool, our very own star

Where does the sun get energy from ?

The sun is made of plasma, almost entirely hydrogen and helium. Plasma is superheated matter that is so hot that it is beyond a gaseous state.

Our Sun is amongst the top 10% by mass, but is still relatively small by comparison with some of the giants. Most of the stars in our galaxy are less than half the mass of our sun.
The sun's energy output is produced by nuclear fusion of hydrogen and helium.
The process of fusion constantly creates heavier elements in the core of the Sun, although some are also rapidly destroyed.
Hydrogen gas is the predominant element of the sun, accounting for some 74% of its mass, and 92% of its volume.

Helium accounts for 24% of its mass but only 7% of its volume.

Traces of oxygen, iron, silicon, sulphur, carbon, neon, nickel, magnesium, calcium and chromium make up the missing percentage.

where did all of the Sun's plamsa come from ?

Basically the suns inner material..mostly hydrogen is crushing itself by its own weight and the preasure and temp over a milion degreess F. shoots electrons into the helium super heating it into the plasma.
 
Isometric map of our "Solar neighborhood" within about 14.5 light years of the sun. The nearest star at 4.4 light years, Alpha Centauri-A (actually not quite as close as Proxima-Centauri), like the sun is a G-class dwarf. It is almost a perfect "brother" star, except that it is 1.5 billion years older. Being a "brother" star means that it is about the same size, and has about the same metallic/elemental content as our sun. This means it is more likely to have the same types of planetary bodies circling it as our own sun has.

The numbers shown are distances in light-years. The stars’ sizes are scaled relative to each other, not to the distances between them.

except for nuclear energy; and of course geothermal energy
Everything here came from the same dust cloud that ended up as the sun.
Sorry Dude, coelescing from the same material as the solar accretion disc that became the sun is not the same as "comes from the sun, IMHO. Grudgingly, Ed seems to have it all covered
I'm talking meta-macro here.....Process, not content.

The same physics apply.
 
the bible clearly states that half the energy comes from the sun during the day and the other half comes from the moon since the sun is 'gone' during the night. the bible is scientifically accurate or you hate god

Gravity is a harsh mistress when she starts defeating weak and strong nucleic forces.

The best description of what plasma was, for me, is a gas so excited that not even the individual elements of the atom can stay together and thereby breakdown and constantly reform.

Now if only we could harness that energy... dependably and safely. In theory that's the holy grail of energy, and we are at least a century away from doing so reliably.
