I'm actually not sure what you're getting at. We're certainly not economically disadvantaging ourselves to cut carbon emissions. Thanks to kickstarting by government subsidies, the renewable energy industry is doing pretty well in many parts of this country. That's an industry in the process of growing and maturing, and I'd say that's a healthy sign. Although several auto companies are working on electric cars, the demand here isn't that great for them and they are still pricey, so thus far they aren't selling that well, and that's as it should be. If we were forcing people to buy them then I'd agree with you, but we're not. The only industry that has really suffered is the coal industry, and that's due more to the low cost of other fossil fuels (especially natural gas) than emissions cutting policies.
We could be doing more without hurting ourselves... IMO we should be trying to keep existing nuclear plants alive where there aren't real safety concerns, and we could ease the regulatory burdens on new, modern design nuclear plants to make it less onerous to build and bring new plants online. But that's a matter of political will, and public fear of anything "nuclear".
