Now is the time for the Republican-led congress to pass a carbon tax, says Michael Webber, deputy director of the Energy Institute at The University of Texas at Austin. Webber believes that corporate support, collapsing oil prices, and the chance to create political leverage all converge to make this the right to put a tax on carbon. And what about those falling oil and gas prices? Webber believes they are here to stay. As for the Keystone Pipeline, he believes that the pipeline will be built, but underutilized for a variety of reasons. Webber is a general expert on a wide range of areas related to energy.
