UC Berkeley law professor Dan Farber lists the top ten problems he sees with Mitt Romney's energy proposal. That proposal is different from the energy policies in the Republican platform we've reviewed here, but has a lot in common with it.
Farber's #2 problem is promises of energy independence:
2. It makes an unfounded claim to achieve energy independence for the United States. Energy economists say this goal is “unattainable.”
And #1 is the proposals failure to address climate change in a meaningful way:
1. The economists’ view is that ” it is a lot less costly to control greenhouse gases now then it is for future generations to suffer the costs of climate change.” But the GOP platform calls for a fossil fuel feeding frenzy that would cause massive increases in carbon, helping to damage the planet for generations to come.
I recommend the whole list - it's a quick read.
