TL;DR: Li et al. as mentioned in this paper developed ELITE cities, an eco and low-carbon indicator tool for evaluating cities (ELITE cities) to evaluate cities' performance by comparing them against benchmark performance goals as well as rank them against other cities in China.

TL;DR: In this article, the authors used the Desalination Economic Evaluation Program developed by the International Atomic Energy Agency (IAEA) to compare coal and nuclear desalination with the currently planned South-North Water Transfer Mega-Project and show that, while the short-run cost of water diversion is lower, critical vulnerabilities and future resource demands favor nuclear desalinination over water diversion.

TL;DR: In this article, the authors examine emerging efforts by cities around the world to shift to a development pattern with less energy and less carbon, and present key steps in low carbon development.
Abstract: Cities consume more than 60% of global energy and that share is rising with the rapid rate of urbanization. With cities playing a crucial role in sustainable energy and climate systems, this article examines emerging efforts by cities around the world to shift to a development pattern with less energy and less carbon. We review metrics that define a low carbon city and present key steps in low carbon development. We examine city-level inventory methods and target setting. Much of the article is devoted to examples of policy measures that cities are pursuing to save energy and carbon, from net-zero buildings and 20-min neighborhoods to distributed and renewable urban energy supply.
Keywords:

TL;DR: In this article, He et al. examined the implications of the solar and wind variability and availability in the context of an overall energy strategy for China by using a system optimization model: SWITCH-China to analyze the feasibility, costs and benefits of China's clean power transition under three key policy scenarios: Reference Scenario, Low Cost Renewable Scenario and Carbon Cap Scenario.
Abstract: Author(s): He, Gang | Advisor(s): Kammen, Daniel M. | Abstract: China’s power sector accounts for 25% of the world coal consumption–fully about 13% of total global carbon emissions from fossil fuel. Decarbonizing China’s power sector will shape how the country and to a large extent the world uses energy and addresses pollution and climate change. Combining methods of GIS modeling and wind and solar capacity factor simulation, this study utilized 200 representative locations each independently for wind and solar, with 10 years of hourly wind speed and solar irradiation data to investigate provincial capacity and output potentials from 2001 to 2010, and to build wind and solar availability profiles. This study then examined the implications of the solar and wind variability and availability in the context of an overall energy strategy for China by using a system optimization model: SWITCH-China to analyze the feasibility, costs and benefits of China’s clean power transition under three key policy scenarios: Reference Scenario, Low Cost Renewable Scenario, and Carbon Cap Scenario. By optimizing capacity expansion and hourly generation dispatch simultaneously, SWITCH-China is uniquely suited to explore both the value of and synergies among various power system technology options, providing policymakers and industry leaders with important information about the optimal development of the electricity grid. China’s power sector is in the midst of fast development, and today’s investment decisions will have a large impact on the country’s ability to achieve its environmental and carbon mitigation goals. Concerted actions are needed to enable such a transition, including introducing a meaningful carbon price, coordinating the investment decisions, and building the necessary infrastructure for moving energy around.

TL;DR: Results show significant benefits potential for technologies such as distribution voltage and VAR control and utility-scale batteries, while a 22-residence zero net energy home demonstration inspired by California’s 2020 residential energy efficiency standard falls far short of economic breakeven at the current stage of costs and technology performance.
Abstract: Author(s): Karali, Nihan; Marnay, Chris; Yan, Tyler; He, Gang; Yinger, Robert; Mauzey, Josh; Clampitt, Kevin; Zhu, Han | Abstract: Smart grid technology is being rolled out around the world, with the United States nearing completion of a particularly significant 4 plus billion-dollar Federal program funded under the American Recovery and Reconstruction Act (2009). Under the Climate Change Working Group Implementation Plan, Smart Grid activity comparative analyses are being conducted of benefits estimation methods with example applications to 4 case study smart grid projects, 2 in each country. In this first study, three of eight Southern California Edison’s Irvine Smart Grid Demonstration Project sub-project benefits have been analysed over the period 2010-2035. The analysis uses the Smart Grid Computational Tool (SGCT) developed by Navigant Consulting Inc. for the U.S. Department of Energy based on Electric Power Research Institute methods. Results show significant benefits potential for technologies such as distribution voltage and VAR control and utility-scale batteries, while a 22-residence zero net energy home demonstration inspired by California’s 2020 residential energy efficiency standard falls far short of economic breakeven at the current stage of costs and technology performance. The experience gathered indicates the SGCT being intended for widespread U.S. smart grid evaluation use is necessarily simple, and consequently has limited applicability for international applications or comparisons.
