It varies a lot, depending on the size of the TV, also on the technology. The big bulky (CRT) television sets use more energy than the modern flat-screens. Look around the television set; somewhere, perhaps on the back, there should be a small firmly attached sticker with the electrical specifications. If it doesn't tell you the number of watts the set uses, look for amperes and volts, and multiply both to get watts.

As LCD technology advances, the power consumption for televisions is falling. Where a CRT television could use 200 Watts, an LCD version is typically around 100W for a 37 inch. Larger screens will inevitably use rather more but even at 50", the power consumption is only around 150W for many screens.
