Disagree with Chris Nelder on the reasons why we're not energy independent
Sure, he's correct on the wide variety of needs and the humongous needs that a robust economy demands.
But, the U.S. could have been energy independent many years ago. The only reason that we are not, is because of the many hurdles put in front of the energy sector by a massive number of regulations which prevents them from seeking and developing the huge number of energy sources available to the oil and coal and natural gas industry. Whatever is being developed now, is in spite of the attempts to handcuff the energy industry, and if government had its way, we could all be riding around in bicycles and waking to most places we need to get to.
When people focus on just one narrow aspect of the overall problems with our demands for energy, then, the most important questions won't be addressed.
