Many of the wastewater systems that Americans rely on to protect public health and the environment are reaching the end of their useful lives. The EPA has estimated that a potential gap between future needs and current spending for wastewater infrastructure of $150 billion to $400 billion could occur over the next decade. Various approaches have been proposed to bridge this potential gap. One is to establish a clean water trust fund. This testimony summarizes findings of a May 2009 report which examined: (1) stakeholders' views on the issues that would need to be addressed in designing and establishing a clean water trust fund; and (2) potential options that could generate about $10 billion annually in revenue to support a clean water trust fund.

While direct electrification appears to provide the most cost-effective route to decarbonization of commercial vehicles, uptake may be constrained by critical metal supply. Additionally, it will be many years before hydrogen power becomes decarbonized or if it can ever compete economically with direct electrification. An electric road system (ERS) could offer a highly efficient and cost-effective route to direct electrification that would greatly reduce the volume of batteries required, but pilot schemes are urgently needed to provide concrete data on operating costs for different ERS technologies. Furthermore, if plug-in hybrid electric vehicles could obtain most of their power from an ERS, liquid biofuels and “electrofuels” may prove useful for occasional off-grid range extension. To achieve extremely long-range for operation in remote locations, liquid fuels remain the only viable option. Unsettled Issues Regarding Power Options for Decarbonized Commercial Vehicles discusses the analysis required to understand the lifecycle energy use for different power options for decarbonized commercial vehicles.
