Well, it is certainly important to understand that technology by itself does not increase average fuel economy. Regulations that require cars to be more fuel-efficient do increase the average fuel economy of a car on the road. But it is entirely possible to use even the hybrid technology for heavier vehicles, for more power, rather than for fuel economy. So it's really the government requirements that bring about fuel economy, not the new technology per se. So there is no silver bullet technological fix. If you want to reduce greenhouse gas emissions, you're going to need federal regulations and federal action.
