| Summary/Abstract |
Climate change policy involving a price on carbon would change the mix of power plants and the amount of water they withdraw and consume to generate electricity. We analyze what these changes could entail for electricity generation in the United States under four climate policy scenarios that involve different costs for emitting CO2 and different technology options for reducing emissions out to the year 2030. The potential impacts of the scenarios on the U.S. electric system are modeled using a modified version of the U.S. National Energy Modeling System and water-use factors for thermoelectric power plants derived from electric utility data compiled by the U.S. Energy Information Administration. Under all the climate-policy scenarios, freshwater withdrawals decline 2-14% relative to a business-as-usual (BAU) scenario of no U.S. climate policy. Furthermore, water use decreases as the price on CO2 under the climate policies increases. At relatively high carbon prices (>$50/tonne CO2), however, retrofitting coal plants to capture CO2 increases freshwater consumption compared to BAU in 2030. Our analysis suggests that climate policies and a carbon price will reduce both electricity generation and freshwater withdrawals compared to BAU unless a substantial number of coal plants are retrofitted to capture CO2.

| Summary/Abstract |
As states consider revising or developing renewable portfolio standards (RPS), they are evaluating policy costs, benefits, and other impacts. We present the first U. S. national-level assessment of state RPS program benefits and impacts, focusing on new renewable electricity resources used to meet RPS compliance obligations in 2013. In our central-case scenario, reductions in life-cycle greenhouse gas emissions from displaced fossil fuel-generated electricity resulted in $2.2 billion of global benefits. Health and environmental benefits from reductions in criteria air pollutants (sulfur dioxide, nitrogen oxides, and particulate matter 2.5) were even greater, estimated at $5.2 billion in the central case. Further benefits accrued in the form of reductions in water withdrawals and consumption for power generation. Finally, although best considered resource transfers rather than net societal benefits, new renewable electricity generation used for RPS compliance in 2013 also supported nearly 200,000 U. S.-based gross jobs and reduced wholesale electricity prices and natural gas prices, saving consumers a combined $1.3–$4.9 billion. In total, the estimated benefits and impacts well-exceed previous estimates of RPS compliance costs.

| Summary/Abstract |
Shortages of water and geographically uneven distribution of coal and water pose great challenges to sustainable development of the coal industry in China. In this paper, we illustrate the major challenges existing in the coal industry from a supply chain viewpoint, and propose technical and policy suggestions to address them. First, we provide quantitative information about water withdrawal, consumption, waste water recycling and treatment and pollution from coal mining, preparation, to final conversion for China's power generation and coal-to-chemical industry. We then analyze scenarios of water use in China's coal industry between 2020 and 2030. Our results show that water issues are becoming increasingly severe constraints for coal development in China, especially in North and West China, where water is more scarce and ecological systems are more vulnerable than other regions. Without implementing effective water-saving measures or regulations the water demand in the coal industry could dramatically increase and probably exceed China's water supply capacity in the near-term future, bringing substantial uncertainty to sustainable development of China's energy economy. We also illustrate that coal-fired power generation, with appropriate technical improvement and proper policy supports, has the greatest potential for water savings in the coal industry. Our conclusions also underscore the importance of expanding energy efficiency and renewable energy in China so as to limit the country's dependence on coal.
