Do you love those displays of Christmas (or Hannukah or Kwanza or …) lights? Are you awed by those so impassioned that they string up 1000s of lights in awesome displays worthy of a city center? I once did, pausing on cold winter nights, white clouds issuing from my mouth, enjoying being in the glow of beautiful displays. And, in a way, I was inspired that they would spend $1000s (or $10,000s) on displays and the electricity to power them so that others could enjoy the sight on those cold winter nights.
But … no longer … not for awhile. Far too often nowadays, my winter evenings I can wear short sleeve shirts 
rather than bulky coats and gloves. And, energy is no longer a question simply of money. I’ve reached the point of feeling like a Scrooge; feeling outrage over the tons of C02 going into the atmosphere via neighbors’ 10,000 light displays rather than feeling ‘joyous’.
But, a compromise does exist; a path to cut sharply those CO2 emissions while still putting out those lights: LED lights. But, far too many are unwilling to spend the money upfront to cut their electricial use, reduce their pollution, and — actually — save quite a lot of money.
