Carbon dioxide. Source: Burning fossil fuels like coal, oil and natural gas.

Methane. Source: Cattle emissions, farming practices, melting tundra, coal seam fracking.

Water Vapor. Source: Earth's water cycle. Water vapor does not contribute to global warming, just to the natural greenhouse effect.

How much greenhouse gases does a television emit in a year?

The actual television sets emit no greenhouse gases at all. The connections you could make between a TV set and greenhouse gases would be the emissions during the manufacturing process, and the greenhouse gases emitted as the powerplant generates electricity to run the device. The amount depends on the size of the set and how long it is running. If your TV is powered by electricity from nuclear or renewable sources, then it causes no greenhouse gases at all.
