Back when LCD panels were first introduced as replacements for CRT computer monitors, they were heralded as not just a way to save space but a way to save energy as well: They used far less power and produced less heat than CRTs of the same size, which means buildings would spend less on air conditioning, too.
But as flat-panel technology moved to the television market, things started to change. Namely, LCDs and plasmas started to get a lot bigger than the largest CRTs available. Now you hear very little about power consumption of flat panels. I thought I'd take a look at how things have changed in recent years.
First off, it's actually quite difficult to find power consumption information for television sets. Very few vendors report the stats on their websites, and many bury them pretty heavily. (Tip: If you want to find the information reliably, look in the user manual on the specifications page, usually one of the last pages in the manual. Many manuals are online in PDF format now.)
So how do CRTs, LCDs, and plasmas stack up? Here's some data on roughly similar size sets offered by the same vendors.
