Answer 1

TFT panels save up to 40% of electricity consumption as compared to CRT monitors, TFT panels pay for themselves in energy savings. A typical 15" CRT monitor consumes 60~100Watts where a 15" TFT panel consumes 32Watts. This savings in energy is not limited to usage from the electrical outlet. Additional savings are found by the reduction in heat in a room which reduces air-conditioning energy consumption costs.

here are some good resources for energy calculations -

Answer 2

A Typical 19 inch CRT consumes about 100~150 Watts while a TFT only consumes about 75 Watts. That means it will consume about 525 Watts per day (7h). That means you will save more that 40% in your overall Monitor Energy Consumption. In addition to that, you can turn on Energy Save Technology to Turn off your monitor when the computer is not used...

Good Luck

I work in Law enforcement and we used 21 inch Viewsonics tft's 24/7 365 for years, they can handle the load...so ur kewl down sizing it if you need to, most of the power is consumed by the monitor and cpu itself...

If you run the computer 5 Hr. a day , it will consume about 50 unit electricity
