Screen size and power consumption

Generally, the larger the screen, the more power the TV consumes.

While this may look pretty straightforward, the equation isn't always linear. That means a 40-inch TV won't consume exactly twice the amount of energy as a 20-inch one.

Usually the equation tapers off, but this depends on the brand, model, make and technology of each TV available in the market.

As a guide, a 52-inch LCD TV will consume about twice the amount of a 32-inch model, even though the screen space real estate on the 52-inch is about three times as large.
