Your question leads us to try and come up with what creates energy and that is not going to happen.
I suppose you are asking what conversion processes exist and which is best for your needs or the needs of the general population.
The energy in fossil fuels is converted to heat and the most popular source is coal because it is least expensive. That heat energy from coal is then converted to electricity at most power plants.
The energy in petroleum is converted to kinetic energy in your car's engine. Since we buy millions of barrels per day, one can assume it is the most popular.
The energy coming from atomic fusion is the greatest energy used on the planet. We get it from the sun. We can capture that energy and convert it to electricity too. Not only is it our planet's greatest source of heat, but also is the greatest source of light. Given the number of people sunbathing at the pool, one can assume it is the most popular, too. Atomic energy can also be pulled from uranium and turned into electricity or used to destroy entire towns. One is popular, the other is not.
Please add some more info to your question. It is too vague for me to answer well. Just as minootoo points out, the pros and cons of ALL sources of energy is beyond the scope of this forum.

There are all the forms of fossil fuels - crude oil, coal, natural gas, etc.
These are not sustainable(i.e, they run out as we know all too well) and are not particularly environment friendly. Also most appliances that make use of these are not the most efficient ones, though efforts are being made to rectify this.
Then there's solar power, the problem with this is that current generation solar cells are extremely inefficient and to meet upto demands we need a truckload of these. Research is being done and a new type of solar cell developed by MIT seems promising.
Using windmills and sea currents are also gaining popularity and are lucrative options for going green, with enough research these could be a wave of the future.
Then there's hydrogen power using fuel cells and the like, but this leads in two directions, read http://en.wikipedia.org/wiki/Hydrogen_energy
for more.
Hope this helps!!

There are all kinds of energy.
To list a few:
Kinetic
Potential
Static
Light
Heat
Electric
Magnetic
........................
.........
...
See if you can come up with few more.
They can be derived from various sources.
To name a few:
Sun
Moon
Rotation of the earth
Various fuels such as, coal, fire wood, oil, gas........think of few more and think what part Rotation of the earth plays.
There are many Pros and Cons, there are volumes written on them with lots of controversy and lots of misconceptions, I cannot beginning to tell you in this forum.

the most popular source of energy is heat energy obtained by burning fossil fuels like wood,coal,petrol,diesel etc.
another source of energy is the nuclear energy obtained by the fission of elements like uranium
then we have wind energy,wave energy,geothermal energy,water energy (flowing water stopped by means of dams and used for producing hydro electric energy)
we can use burn biomass to again get heat energy
the subject is rather vast
this is only a bird's eyeview and by no means exhaustive
