Home lighting is a miniscule part of our power requirements ~ and in any case, EVERY SINGLE BULB has its own switch and is normally in an OFF state. Consequentially it is virtually impossible to gauge what incandescent light usage was and it's equally impossible to determine what benefit any switch to CFLs for home lighting could possibly deliver.
Having said that I cut my monthly power bill $50 by converting totally to CFLs some time back. My LCD TV whacked another $25 per month out of my bill ~ which actually surprised me!
Getting my eldest to move to his own home gave me $18 per month (from the hot water bill) and $33 per month from the reduced water usage!
Oh, happy day!
LCDs use CCFL backlighting. Present LED TVs are still LCD but with LED backlighting and could knock another $25 off you bill.
Ug. Florescent lights good; compact florescent lights bad.
"Energy Management" has been a snake-oil scam for decades. "Green and sustainable" is the FedGov subsidized continuation of the scam.
