[ILUG-Social] OT: LCD vs CRT and energy usage

[Joe Desbonnet]

I think 17in CRTs have power consumption in the order of 200W or so. Assume
10 hours of useage/day x 300 days thats 600 KWh / year. I think ESB is
approx 10c/KWh ... so thats approx 60 euro per year running costs.

Makes a difference, but only over the lifetime of the device.... you also
get a whole lot more desk space. Other things that are "nice" about LCD:
they are easier and safer to dispose. Easier to lift and carry (ever try
carrying a 21" CRT down stairs!). Dissapate less heat (probably a
disadvantage in Ireland :-). Not prone to interference from nearby power
cables or other CRTs.
