> Electricity doesn't inherently do that. No, but for the moment it does actually do that. And you can change what sort of light bulbs people use faster than you can change your large-scale power generation technology. (I do agree that making environmentally-better energy cheaper is likely a more powerful way of reducing the environmental cost of electricity use than telling everyone to stop using incandescent bulbs. But "X is better than Y" is a reason for doing X, not necessarily a reason for not doing Y.) > a law against powering incandescent bulbs on coal power Enforcing that one would be an interesting challenge. A law that says "no selling incandescent bulbs" is rather easier to enforce.
