Thanks for the graph.
Actually, the energy savings from abandoning incandescents is even less than that illustrated in the graph.
As I always point out when this topic is raised, it’s automatically assumed that the 90 - 95% of energy not given off as light in an incandenscent is wasted. That is sometimes true, but usually not.
That remaining energy is lost as heat. Anytime you’re heating your home, that heat is not wasted - it simply adds to the net warmth, and hence decreases the amount of energy you have to use to run your furnace.
When your home heating is off, heat from the bulbs is wasted; when your AC is on, it’s doubly wasted, since you have to “fight” the waste heat by using more AC. But the latter situations occur in late spring/summer/early fall, when days are long and lights are used less.
I expect the manufacure of LCD’s and LED’s are more energy-intensive than incandescents as well.
Bottom line - the whole farce makes almost no difference in practical terms, it just makes enviro-weenies feel good about their self-righteousness.
You are probably right...I assume that the gray lines to the right of wasted energy incorporate that, but now that I think of it, they might not.
Yeah. Enviroweenies have this amazing capacity for self-righteousness and smugness. I had kind of a funny experience last week, my wife and I went to New Mexico on vacation, and ended up renting a Chevy Malibu (which I completely thought was a piece of crap to drive, but...my wife didn’t want to splurge. I thought a Dodge Charger or Mustang would have been fun on vacation to drive around New Mexico, but...she planned it, so she got to choose...:)
Anyway, I have never driven one of the new Mustangs, and when we were returning the car, I saw an older couple returning a Mustang. As we got on the shuttle to the airport, I thought the couple (a couple of early sixty hippie looking types, but one can never tell) was sitting across from me.
I asked “Excuse me, I was just curious...did you folks rent a Mustang...I was just wondering how it was to rent one?”
The guy and his wife looked at me incredulously, and said smugly with a tone of superiority “Oh, no. We would never rent a car like that. We rented a Prius.”
Obviously, I had mis-recognized them, and clearly, some people would rent a car like only because it would use less gas driving and would save some money, but the tone of voice and look on the face said it all...what their voices and faces said was:
“Oh, no. We would never drive a bourgeois and wasteful car like that which guzzles gas needlessly and destroys the environment the way most Americans are indifferent to. We care, and want to protect Gaia.”
It was everything I could do to keep from bursting out laughing...
