From The Hill:

Many of the projects that we most need for a clean-energy transition face particular permitting difficulties because they require permits from multiple states or communities and the federal government. Our traditional energy commodities, oil and coal, are less dependent on building long-distance infrastructure because they can rely on existing railroads and pipelines, and they are easier to ship by rail, road or waterways. By contrast, products such as renewable electricity, natural gas and hydrogen can be shipped only through new, long-distance infrastructure. So, to clean up our energy system we must speed up permitting reform to be able to build the infrastructure.
