The Sony Bravia is a high-end high-definition television line that comes with automatic power-saving features as well as an energy saver switch that has an effect similar to unplugging the TV. The WE5 Bravia line is Sony’s eco-friendly design and has even more energy saving features.
Sony Bravia Line – The Sony Bravia TV line encompasses many different models, including the standard HDTV set, which comes in 32-inch, 46-inch, 55-inch and 60-inch sizes, and there’s also the WE5 Eco TV, which comes in 40-inch and 46-inch sizes. The WE5 line was specifically designed to reduce power consumption by as much as 30 percent without sacrificing picture quality.
General Energy Use – The energy consumption of the Sony Bravia depends on the size of the TV. The average energy use can range anywhere from 90 to 170 watts per hour while operational. While in energy saver or off mode the TVs use only about 0.2 watts of energy per hour. The amount of power the TV uses will also vary depending on what you’re watching and how well the TV is calibrated. Just as an estimate however, assuming a 46-inch TV and proper calibration and an average movie — you can expect to burn through about 80 watts an hour.
WE5 Energy Use – The WE5 Eco TV line uses a special HCFL backlight that uses 50 percent less energy. It also has special features such as a sensor that can tell if there are people in the room or not, and if no one is in the room for a set period of time it automatically turns itself off. In general it can save about 30 percent total energy over the general Bravia line. The WE5 line uses only about 80 to 100 watts per hour.
Saving Energy and Money – If you’re looking to save energy and money when TV shopping, look for TVs that are Energy Star compliant, which includes the Bravia. Energy Star says that certified televisions are generally at least 25 percent more efficient and can potentially save you money in energy over the life of the TV. If every component in home entertainment systems in 2013 were Energy Star compliant, the United States could prevent over 2.2 billion pounds of greenhouse gas emissions per year, according to Energy Star.
