The Big Green Tick – Power Efficiency In Tvs
The wild swings in the weather patterns that we're used to, the dire scientific data that is constantly being published and the fact that all politicians can find to talk about is the weather, has made all of us much more eco-conscious than ever before. We want to preserve the world we live in as it is, understandably. However, that doesn't mean having to compromise on the quality of your television. LCD televisions are now especially green-friendly, with automatic features that help reserve power when it isn't needed. There are quite a few models that get the consumer's ‘green tick' of approval, from the ranges of Samsung TVs, Sony TVs and Sharp TVs.
Plasma vs LCD vs cathode ray televisions
In general, in the hierarchy of television power consumption, plasma televisions sit at the top, using around 338 watts while turned on. LCD televisions come next, with about 176 watts of power used while turned on, with the LED variant of LCD televisions being inherently more efficient. Cathode ray televisions (the old, heavy models) use the least power – but there is a catch. Per inch of screen size, cathode ray TVs are actually the least efficient. It is simply because of the limited screen size that on average, these sets use less power.
Picture brightness and its effect on power usage
Picture brightness is actually the leading cause of power usage fluctuations among LCD televisions – and this is ultimately within your control. Your power usage may in reality be much higher or lower than the manufacturer's stated average, if you tend to set your picture brightness either above or below the test levels. In some cases you can cut your power consumption by half, by reducing the backlight levels of your LCD television. This is usually separate to the more familiar ‘brightness' control.
Standby power
In some cases an Energy Star, or other energy accreditation rating, is assigned based on standby power usage alone. Most sets use between 0.1 and 1 watt in standby power – a 1 watt set would cost around $1 to run for a year turned off, so the difference here is negligible. Don't depend solely on these energy accreditation ratings if you want to ensure that your new set is as energy efficient as possible – compare the actual wattage used in operation.
Model comparisons
* Samsung LCD TV 22″, operation power consumption 60W
* Samsung LCD TV 32″ , operation power consumption 130W
* Samsung LCD TV 37″ , operation power consumption 180W
* Sharp LCD TV 32″, operation power consumption 152W
* Sharp LED TV 40″, operation power consumption 160W
* Sony LCD TV 22″, operation power consumption 48W
* Sony LCD TV 32″, operation power consumption 99W
* Sony LCD TV 40″, operation power consumption 165W
As you can see, the power savings you can make through purchasing a smaller screen size LCD television always trump the savings that you can make by purchasing different models. The way that you use your TV will always be the main determinant of cost, though. Spend less hours watching television, and turn it off when it isn't being watched, and you will naturally see the effect in your power bill … and your feel-good factor for environmental responsibility!
