Can we possibly warm Mars and Neptune by putting CO2 into the air? I don't think so. I doubt there are CO2 machines going on there, and besides CO2 is rather mild as a greenhouse gas (water vapor is stronger).
All that to get your old light bulbs banned. Use the squiggly things, because the older incandescent bulbs are being phased out. I don't know what they are planning for LEDs yet--I switched my squlggly things out for LEDs and got a reduction of 55 watts per bulb-hour in actual usage. (For 26 watt squigglys and 13 watt LEDs). Anyone still using incandescent bulbs can be guilted as "ruining the earth by heating the planet", and those buying squiggly things (especially the GE ones) gets the self righteousness boost. (Anyone else wonder what the other 42 watts was doing?)
