Conservatives did not suggest this, Obama himself suggests it. If you want to encourage research and development into new energy sources, forcing additional regulations on energy companies is the wrong approach.
Here is the Obama quote from the January 2008 interview.
The problem is not technical, uh, and the problem is not mastery of the legislative intricacies of Washington. The problem is, uh, can you get the American people to say, “This is really important,” and force their representatives to do the right thing? That requires mobilizing a citizenry. That requires them understanding what is at stake. Uh, and climate change is a great example.
You know, when I was asked earlier about the issue of coal, uh, you know — Under my plan of a cap and trade system, electricity rates would necessarily skyrocket. Even regardless of what I say about whether coal is good or bad. Because I’m capping greenhouse gases, coal power plants, you know, natural gas, you name it — whatever the plants were, whatever the industry was, uh, they would have to retrofit their operations. That will cost money. They will pass that money on to consumers.
They — you — you can already see what the arguments will be during the general election. People will say, “Ah, Obama and Al Gore, these folks, they’re going to destroy the economy, this is going to cost us eight trillion dollars,” or whatever their number is. Um, if you can’t persuade the American people that yes, there is going to be some increase in electricity rates on the front end, but that over the long term, because of combinations of more efficient energy usage, changing lightbulbs and more efficient appliance, but also technology improving how we can produce clean energy, the economy would benefit.
If we can’t make that argument persuasively enough, you — you, uh, can be Lyndon Johnson, you can be the master of Washington. You’re not going to get that done.
