I'm blown away by how many people today want the government to make decisions for them --or perhaps more accurately, want the government to make the decision for others when it's a decision they like for themselves.
I would not want to speculate on the savings in light bulbs vs the savings in vehicles but I can tell you that it made a sizable difference in my electric bill when I changed to CFL. I have a couple rooms where turning a light switch on ignites a new generator at the power plant...LOL. My 75 watt bulbs are now using 13 watts but still providing the same amount of light as the incandescent bulbs.
A quick comparison of energy usage.....a gallon of gas is equivalent to about 33 kWhr. Using your 75 watt bulb replacement as an example....you save 62 watts, or .062 kW. So, you'd have to run that 13 watt bulb for 532 hours to save as much energy as reducing gasoline consumption by 1 gallon. If your vehicle got 19 mpg instead of 20 mpg, and you traveled at 20 mph, in approximately one hour you'd save as much energy as as it would take 532 hours for the light bulb to save. So, the vehicle is only 5% more efficient, while the light bulb is 83% more efficient, but the amount of energy saved is 532 times greater for the vehicle --which is why an efficiency comparison between the two is irrelevant.
