The first part of your question is not correctly stated. You are asking for a comparison between energy (measured in TeV) and power (measured in W). In addition, the 7 TeV is not produced by the LHC. The energy is channeled to the LHC by the French electric utility. That energy is then used to accelerate protons such that when a proton from one beam interacts with another proton from the counter-rotating beam, the center of mass energy released in the collision is 7 TeV.
Obviously, this is not more than all the energy in the world, as it is a minute fraction of the electric energy supplied by the local utility. By the way, based on Einstein's E=mc^2, the mass of particles can be equated to energy in the proper units (i.e. if you define c=1, then mass and energy are equal). In that system of measurement, the mass of only 7000 protons is about 7 TeV.

7 TeV (Tera-electronvolt) is equal to 1.1215235409E-6 Ws (watts per second). To the next part of the question, I don't know exactly the amount of energy in the whole world. But I don't think this value is equal to the total energy of the world, though I accept that this is a huge amount.

Show how you calculated you Watt equation. I'm calculated alot less wattage.

TeV is a unit of energy. Watt is a unit of power, which is the energy per time unit. You can measure energy in units of power multiplied by units of time (e.g. kilowatt-hours which is kilowatts multiplied by hours, or watt-seconds which is watts multiplied, not divided by, seconds. Thus it is not watts per second.
The issue with the first part of the question is that it is unclear what time period you would use to convert power to energy or vice-versa. The most reasonable would be to use the typical interaction time, which is less than 10^-23 seconds, which would translate the 7 TeV to 1.12 x 10^-6 Joule multiplied by 10^-23 seconds giving about 10^-29 watts, which is extremely small by any human measure.

Where did I go wrong in my conversion?
3.111x10-19 kWh verses 10^-29 watts
Did I miss time in my equation?

One MeV equals 1.6 x 10^-19 joules
3.6 million joules to equal one kWh.
7 TeV = 7x10^12/1x10^6 = 7,000,000 MeV * 1.6x10-19 = 1.12x10-12 joules / 3.6x10^-6 = 3.111x10-19 kWh
The electrical output is not much.
