Nope! Both companies paid off and bought lobbied congress to pass a law requiring the new lightbulbs and ban the others.
This meant there was higher entry cost for other companies that could not retool and/or enter the LED and squiggle bulb market. Meanwhile GE and Sylvania were able to do such.
When they first did the math, for me to change every bulb in my house to "efficient"lightbulbs, barring majorly significant increases in electricity costs, (at the then cost of incandescent/HE bulbs; it was $0.75 per 4 for incandescents; ~$8 for 4 of the others in my area) it would've take me almost 50 years to realize any supposed savings, if and only if the new bulbs never needed replacing in those 50 years.
Dow Chemical did almost the same thing with Freon.
There was really nothing wrong with R12/22 but the patents were going to run out so they gave several million dollars to greenie groups and congressmen and the whole CFC scare started. That gave them the room get R134/410 into place with their new patents.
Now the R134 patent is going dry I read Dow has paid Al Gore a substantial sum as well as a few million to at least two greenie groups to start the tilt at R134/410. They are already selling the new, terribly expensive, R1234YF and the car companies are already using it.
It has nothing to do with any science, it has everything to do with money for all parties involved.
