- account for the economic cost of carbon emissions (there is one)
- promote energy efficiency (because the current growth in US energy consumption is unsustainable)
- make us less dependent on oil. we use 19M barrels a day, and we import 12M (63%) of those. Anyone who thinks we can simply stop importing and triple domestic production, is stupid (and wrong).
We can't stop using coal either, but we can make it more attractive to get our electricity from other sources. The problem is that the coal (and railroad) lobby in this country are ridiculously powerful. They want you to think your energy bills will skyrocket if we implement a cap and trade system, which is just ridiculous. They're simply protecting the status quo and trying to scare people, and shame on Mitch McConnell for joining them. Ask a Kentucky miner to show you some "clean" coal.
