All animals get their energy from the sun. By tracing a food web back it goes to plants or algae which use photosynthesis to live.
There are a few exceptions. Deep in the ocean there are things called geothermal vents where highly heated water with lots of sulphur and other minerals escaspe. These animals feed on that and can survive without the sun it is thought.
As far as energy sources for us go solar power obviously comes from the sun, wind power comes from the sun because of temperature fluctuations that cause wind, coal is petrified wood so that came from the sun because it is a plant, oil was tiny sea creatures that fell to the sea bed 300m years ago or so and turned into oil under anoxic conditions over a long period of time. Wave power also comes from the sun.
Tidal is because of the moon. Nuclear is independant to the sun as well as it uses the metal uranium to trigger nuclear fission. Hydroelectric is to do with the sun because the sun is needed to make water evaporate then fall as rain.
Geothermal on the other hand (the one that comes from hot lava below us) is independent of the sun. Lava is just melted rock under the crust- the very outer layer of the earth we are on. In fact the vast majority of the earth is molten rock or iron, we are just surviving on the very outer skin. Geothermal power stations work by pumping water down through the crust, not necessarily too far- the increasse in temperature heats it to steam and it is taken back to the surface and used to power turbines. This is much like a geyser you might see in Yellowstone.

The Earth is thought to have been formed from particles from the Sun, which due to gravity have combined into a larger mass (forming the Earth). While the outside of the Earth has hardened, the core of the Earth is still liquid (ie where the lava is).
So if you're taking a pedantic point of view (no offence), then geothermal energy is linked to the Sun, as the Sun provided the particles which now provide heat from the Earth's core through its crust.
Again, it depends how directly or indirectly you are talking. While the Moon exerts the major gravitational pull on the Earth's seas creating tides, the Sun also exerts a minor gravitational pull on the seas, and the Earth's rotation is also an influence, so you can't say that tidal power is independent of the Sun.

Having worked in the poker industry for the past 6 years or so I have met most of the greats, so after reading his book (link below) and I asked Doyle Brunson his thoughts on Ungar. He said that he was the most naturally gifted card player he ever met, and there are 3 times as many stories about Stu that didn't even make the book. Really sad story of what addiction can do to you…
This book is well worth a read.

whats that? lava making thr earth warm?
thats from decayed matter though aint it? which got its energy from the sun to live then decay.

but how did the lava get there? is that not from matter that has broken down thru years which initially got its energy from te sun?
im not talking energy to make my iphone work im talking energy in all formats kinetic, rah rah rah. when i move its the conversion of energy from food which was grown thru te sun to kinetic. when the tides move its due to a gravitational force so is that an energy source in itself?

what are energy sources for the earth? Is it only the sun, or are their more?
is gravity an energy source? we can harness energy from the waves and their gravity based arent they?

ok cool. thanks for the replies one more thing someone mentioned when i was talking bout this, about magnetic forces from the poles. i.e the energy to move a compass needle is these magnetic forces. im assuming these are to do with the formation of the earth and its rotation or something? but in essence that although formed from the sun initially is an energy source in itself. so there are three gravitational, the sun and these magnetic. however from reading it seems that the gravitational
and magnetic are potential energys, 'forces' which need other factors to create the energy, which in both cases is mass. the sun however provides an energy in itself in the form of light/heat.
that right?

Essentially, yes. The Earth's magnetic field is (simplistically) created by the movement of molten iron within the Earth's core.
So again, depending on how strictly you're talking about energy directly or indirectly derived from the Sun, the molten core which creates the Earth's magnetic field began life as particles from the Sun.
I'm no expert (surely the geographers and astrophysicists should be answering this), but my understanding is that the Sun is producing the light and heat due to it's chemical composition (mainly hydrogen and helium), and the nuclear fusion that occurs at the core (ie two hydrogen atoms fusing together to form a new helium atom, which releases large amounts of energy in the process).
Again, depending on the strictness of your criteria of allowing what has come (ultimately) from the Sun, nuclear power (which uses fission - ie splitting atoms to release energy - rather than fusion) is an energy source effectively independent of the Sun. Although you could argue that the Uranium used in nuclear fission may originally have come from the Sun….
It depends really on what is the ultimate point of this discussion and line of thinking.

OK there are four fundamental forces, Strong and weak nuclear force which keeps atoms together, gravity which acts on mass (*basic terms), and electro magic fields which act on charged particles (eg radio waves, electricity etc).
Fission nuclear power is generated by breaking large mass particles down into small ones, which is the potential energy stored in the weak and strong nuclear forces being destroyed / released in the form of gamma rays or nuetrons / alpha particles from the components of the atom left over when it "splits".
Fusion nuclear power is pushing smaller atoms together to form a larger atom, again overcoming the strong and weak nuclear forces requires energy, but the resulting strong and weak nuclear forces to keep the bigger atom together compared to overcoming the the two smaller forces to press them together is less so the left over (stored or POTENTIAL) energy is released.
Solar power is direct photon (packet of energy) transformation from the sun, how it works is a material absorbs the "energy" and as a consequence it ejects a electron(s) equal to the energy from it, this is the same as heat and colour (quantization), although the material is specifically design to eject electrons into a "circuit" to generate a flow of electrons or electricity.
Magnetic materials are formed by having an unequal quantity of electron spins in a lattice of an element, this forms things called domains, so in a bar magnet concept one domain / end has a structure where more electrons of the atoms are spinning in one direction and at the other end they are spinning in the other.
Now the hard part..
The concept is that you have to understand that an object can experience a movement (eg a force) when nothing is really interacting with it. When you move something physically or you put something on a desk what is really happening at an atomic level is the atoms cant get any closer together because of the strong and weak nuclear forces I mentioned earlier.
It takes work (eg energy) to overcome a force, so pressing something together requires energy to override strong / weak nuclear forces. enough energy and you get fusion, pulling them apart with enough energy gives you fission.
With magnetics / radio waves etc this is harder to understand because a force occurs but nothing is "making" happen.
Eg two magnets moving together of different domain types repel and the same attract, but there is nothing between them no particles are moving through the air to pull or press, it just "happens" *(actually extremely complicated quantum physics messenger particles) basically the domains store energy and that energy can be used to generate work on any other domain of magnetic material anywhere.
The next biggest madness is that just moving an electron generates a magnetic field, so either making it move by applying a voltage or physically moving it. So if you move a wire in a magnetic field (say made by a bar magnet) the magnetic field will either push or pull the electron and make it move, the moving electron then generates a magnetic field which tries to stop it moving, but it will be less. The faster you move the wire in the magnetic field the more work is done on the electron, so the move they move, the movement of electrons is current (electricity) and there you have it.
You make a motor by doing the reverse, you apply current to the wire and then the magnet domain experiences a push or a pull so it tries to rotate.
That is magnetic induction which is basically how all power is generated (aside for solar), wind turbines turn magnetics which make electrons move in the wire making electricity, instead of the wind you have steam or something from heating up water by burning wood, gas, coal or nuclear power, wave power is just motors in floating things either turning motors or moving magnets or moving wire.
Gravity is just the same as magnetics really except it doesn't have poles ( + or - domains) so really only can be considered an attractive force so pull rather than push.
So everything is being attracted to the next largest mass, so we are being pulled towards the centre of the earth, we don't fall through because the strong and weak nuclear forces keep the atoms part (as well as atomic structure bonding energy)
So tidal is just the moon pulling the sea off the earth which makes it move, which then can be used to make magnetic induction.
Hydro electricity is just water falling from height into a turbine (attracted down by the earth) used to make magnetic induction.
Geothermal is just the extreme pressure in the centre of the earth (eg pushing everything together overcoming strong and weak nuclear forces, atomic bonds etc) which generates loads of energy giving you a molten core. As it is made of iron it also has magnetic domains which generates the north and south poles and the earth magnetic field (massively simplified).
The magnetic field keeps dangerous particles out and keeps the atmosphere in (combined with gravity) differences in pressure, air density and temperature makes wind where the atmosphere is trying to equalise out all the time everywhere. So it moves and generates wind (note wind is a physical force, actual particles are moving and hitting wind turbines etc).
So the energy there really is trying to get to a balance but it never can, if we had enough wind turbines we could take all the energy out of the atmosphere in theory but that is impossible to acheive.
So what is free energy here, well solar is free because it comes from the sun directly which will not run out, but it produces very little and as it is not magnetic induction based cannot be scaled for large (GWatt) systems, wind is free because we will not use up the stored energy of the atmosphere any time soon, but it is not constant and massively inefficient, tidal is free as it runs from gravity but getting it back to shore to utilise and scale is very difficult plus non constant.
Hydro is free but is not everywhere, but generates constant energy.
And everything else is just heating up water to make steam to turn turbines to make magnetic induction, obviously fission is the best but has its downsides, fossil fuels will run out as it is potential energy made millions of years ago and is limited, and fusion without the free gravity generating the pressure for heat (like the sun) has an equation like.
Use all the energy of the USA grid IN one big laser blast = All the energy back + 10%, but how to effectively use those energy pulses is still unknown (eg too hard to use steam / magnetic induction)
obviously a massive topic.

Said to be the strongest material ever measured, an improvement upon and a replacement for silicon and the most conductive material known to man, its properties have sent the science world - and subsequently the media - into a spin.
Three million sheets of graphene on top of each other would be 1mm thick
"Our research establishes graphene as the strongest material ever measured, some 200 times stronger than structural steel," mechanical engineering professor James Hone, of Columbia University, said in a statement.
"It would take an elephant, balanced on a pencil, to break through a sheet of graphene the thickness of Saran Wrap (cling film)."

Bitcoins are kinda interesting, value has rocketed recently. The obvious issue is that it costs more in power/hassle to run the computer mining them than they're worth. Some friends doing it (just out of curiosity) mine maybe $3 worth a night but if you have a fair amount of computing power just going to waste & don't pay for power (university computer labs for example) we figured you might make a couple of hundred a night on all the machines.
