Is it greener to buy to use a new low energy flat screen or a CRT monitor used from the Goodwill?
February 18th, 2011 
charmy The monitor will have a significant (a few hours a day) use. The flat screen uses less energy during fonctionnement.Le CRT is used, so there is no manufacturing and energy, it saves temporarily discharge. It also costs a fraction of the price ($ 100 against $ 10). Best answer:
Answer Larry Lawrence
We need more green to buy the flat screen, but depending on factors such as electricity rates and the amount of time they will be in use, you could save more green with the flat screen.

This sounds like one of those decisions that may take some personal sacrifice to be evironmentally friendly. Obviously, the CRT is the initially cheaper and more environmentally friendly option due to its used status. And, while more expensive to purchase the flat screen has a lower operational cost. In terms of considering just your wallet, how long is the CRT expected to last in terms of its function and then also with respect to system integration (the other h/w & s/w). How long is the flat screen expected to last? To make your enviornmental side of the decision easier, is the CRT in a shop and likely to have a landfill/recycling repreave whether you buy it or not?
My general response is to buy the newer, flat screen monitor. I suspect that you will eat up any manufacturing cost of the flat screen monitor relatively with its operational energy savings both from a financial and an environmental perspective.
There are 2 issues here:
(i) the low energy level of the flat-screen compared to the high energy requirement of the CRT; and
(ii) recycling to save on waste management through reduction of landfill volume.
Energy efficiency principles are based on life cycle costs rather than initial purchase cost. Whether you get the CRT for a tenth of the cost of the flat screen or you get it free, over the course of usage, it will cause more damage to the environment than the flat screen and will be more expensive in the long run.
Recycling is commendable to reduce waste generation volume, save on cost of waste disposal and help the environment. However, it is not every material that is recyclable. That a material looks good and is still working does not qualify it for recycling if the material has components that could potentially negatively impact lives and the environment. There have been several issues such as x-ray radiation, component toxicity (cadmium containing), flickering, high frequency noise, implosion etc. These make disposing CRT in “special” landfills more reasonable that recycling.
Hope these help. See the sources below for more details.
