Modern food, energy, and water (FEW) systems are the product of technologies, techniques, and policies developed to address the needs of a given sector (e.g., energy or agriculture). Wastes from each sector are typically managed separately, and the production systems underlying FEW have traditionally treated pollution and waste as externalities simply diffused into the ambient environment. Integrative management that optimizes resource use presents opportunities for improving the efficiency of FEW systems. This paper explains how FEW systems can be optimized to (1) repurpose or cycle waste products, (2) internalize traditional externalities, and (3) integrate wastes with resource inputs across systems by diverting waste by-products from one system to meet demands of another. It identifies the means for Bclosing the loop^in production systems. Examples include management of legacy wastes from fossil fuel industries (coal and natural gas) and integrative designs for advanced renewable systems (biogas from waste, bioenergy from CAM plants, and solar). It concludes with a discussion of how studying the governance of such systems can assist in tackling interconnected problems present in FEW systems. New governance arrangements are needed to develop solutions that can align with regulatory frameworks, economics incentive, and policies. Four aspects of governances (property rights, policy design, financing, and scale) emerge as tools to facilitate improved institutional design that stimulates integrative management, technology innovation and deployment, and community development. The conclusion offers a framework through which integrative management of FEW systems can be linked to value chains in closed-loop systems.
With the forces of globalization as a backdrop, this casebook develops labor and employment law in the context of the national laws of nine countries important to the global economy - the US, Canada, Mexico, UK, Germany, France, China, Japan and India. These national jurisdictions are highlighted by considering international labor standards promulgated by the International Labor Organization as well as the rulings and standards that emerge from two very different regional trade arrangements - the labor side accord to NAFTA and the European Union. Across all these different sources of law, this book considers the law of individual employment, collective labor law dealing with unionization as well as the laws against discrimination, the laws protecting privacy and the systems used to resolve labor and employment disputes. This is the first set of law school course materials in English covering international and comparative employment and labor law.
The problem of Reactive Power Capability is vital—and it has beenlargely overlooked in the development of competitive generation mar-kets over the past couple of years. One way of solving the problem isthrough Superconducting Magnetic Energy Storage (SMES), which wasdeveloped by American Superconductor. This is one of several reactivepower technologies that have been developed to meet the growingthreat to power transmission—a danger that can affect all users of elec-tricity.SMES (D-SMES) is now a fully commercial technology in use attwo sites in Wisconsin (Wisconsin Public Service Co. and Alliant), withanother system on order for installation in South Africa (Eskom), andanother for metropolitan Houston (Entergy). It basically allows utilitiesto “cache” significant amounts of real power close to customer loads,and inject large amounts of real and reactive power into grids, instanta-neously, simultaneously, and on a distributed basis. Some projects in-creased the delivery capacity into a 200-MW grid by at least 15% (30MW), allowing them to defer line construction by several years at a verylow cost
A significant challenge to the transmission providers reported bythe National Electric Reliability Council (NERC) will be to maintainadequate levels of reactive support for the transmission system in theera of open market competition in the U.S. Unlike real power (MW),the reactive component of power (Mvar) cannot be easily transmittedover longer distances and must generally be supplied at the locallevel.Without adequate reactive power support, portions of the electricpower system can be susceptible to potential voltage collapse or insta-bility according to NERC. Sources of reactive power include generators,synchronous condensers, transmission lines, capacitors, and very spe-cialized reactive support devices generally known as static var compen-sators (SVCs).Demand for reactive power is shaped by the size and type of de-mand, power transactions across the transmission system, and the load-ing of transmission facilities. This demand for reactive power is growingnationwide
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
