I like to talk about power quality and energy management. It seems that I'm often harping on the hidden effects of all of the newer electronic components in lighting, motor controllers, controllers, computers, etc.
In my reading, I found this blog on power quality. It focuses on some of the issues with energy efficiency technologies.
I thought you might enjoy seeing someone else's perspectives for a change.
Make sure you read the comments as that is where the real gems are found.
