What I want is natural gas to be a bridge to a cleaner energy future, not a dam against a cleaner energy future, not a dead end. To get this right, to get the most out of it, we not only have to make sure we exploit natural gas in a clean way - it's a challenge - but we also have to make sure that we are instilling and implementing all the incentives to win solar, nuclear energy efficiency that will make them continually competitive with natural gas in the future.
