When Americans are called on to innovate, that's what we do - whether it's making more fuel-efficient cars or more fuel-efficient appliances, or making sure that we are putting in place the kinds of equipment that prevents harm to the ozone layer and eliminates acid rain. At every one of these steps, there have been folks who have said it can't be done. There have been naysayers who said this is going to destroy jobs and destroy industry. And it doesn't happen because once we have a clear target to meet, we typically meet it. And we find the best ways to do it.
