This presentation addresses the development of physical and regulatory infrastructures for transporting oil, natural gas and electricity in the U.S. Hydraulic fracturing has allowed oil and natural gas development in parts of the country that were not major producers when pipeline networks were built. Is the regulatory structure put in place decades ago sufficient for the expansions needed today? Likewise, wind, solar, and other renewable energy sources are being developed far from population centers, with the electricity they produce transported through transmission lines. Does it still make sense for states to be responsible for siting and construction of interstate lines?
