Does the size of the television screen significantly influence power consumption?
The smaller the TV screen, the less power it uses. On average, a 26-inch LCD TV screen uses less than 90 watts when switched on and costs £20 a year to run. A 40-inch LCD TV uses twice the power and costs twice as much to run. But combine plasma technology with huge TV screen sizes (50 inches), and we’ve seen sets that consume more than 400 watts, and would cost more than £100 a year to run.
