Questions about compact fluorescent light bulbs:
1. how much mercury is in a CFL bulb vs. how much is safe exposure, vs. how much may be generated by electrical power plants
2. how to dispose of a CFL bulb when it is burnt out or broken?
non-mercury-related, but still important questions:
3. isn’t it wasteful to throw away the transformer along with the CFL bulb?
4. when does the increased cost of a CFL (upfront manufacturing costs) break-even with the energy savings?
5. should CFL vs. incandescent usage/sales be regulated and/or mandated? Or should we simply allow the competition in the free market economy to decide?
