The answer isn't always no, actually. As I mentioned, in public opinion polling in both Washington state and the United States, people are willing to pay something to reduce CO2 emissions. The question is how much they're willing to pay.
We have two initiatives that I think are useful. One is a revenue-neutral carbon tax whereby sales taxes, which are the largest tax source we have in Washington state, were cut more than enough to offset the increase of the carbon tax. Even then they rejected it, because, as I said, their concern was that in the future those taxes would be raised. Even in a circumstance in which the cost is initially zero, people worry about it in the back of their mind.
I'm not arguing that carbon taxes are useless. My frustration and what I try to argue about is how, in an environment like that, to do something, which is the challenge that you face as well. That's why I offer the technology, to increase the elasticity of demand, so that the impact upon people is less and they have an opportunity to save energy, save money, and reduce carbon emissions without the carbon taxes. That's the approach I advocate.
