Seit etwa zwei Jahren hat die electrische Beleuchtung so erheblich an Verbreitung gewonnen, dass sie gegenwartig mit Recht die oeffentliche Aufmerksamkeit auf sich lenkt. Die Anschauungen jedoch, welche im Allgemeinen uber die Erzeugung und moegliche Verwendung des electrischen Lichtes gehegt werden, sind sehr unklarer Art und beweisen eine nur geringe Verbreitung der Kenntniss der hier obwaltenden Verhaltnisse. In Folge verschiedener Anfragen uber electrische Be- leuchtungs-Einrichtungen hat sich der Verfasser entschlossen, dieselben in einer Form zu beantworten, in welcher er hofft, dass diese Schrift nicht allein denjenigen Technikern, die sich bisher wenig mit dieser Sache beschaftigt haben, zur Belehrung dienen, sondern auch von einem allgemein wissen- schaftlich gebildeten Publikum mit einigem Interesse gelesen werden wird. Die Schwierigkeit, die sich in dem ersten Theile dieser Arbeit darbot, sowie die wunschenswerthe Kurze des Ganzen moegen manchen Mangel entschuidigen, welcher in dieser Schrift enthalten ist. IV Verfasser giebt sich der Hoffnung hin, dass es ihm ge- lungen ist, einen ganz unparteiischen Standpunkt einzu- nehmen, sowohl in Bezug auf die allgemeinen Fragen als auch namentlich in Bezug auf die Interessen einzelner Fa- brikanten.

This report proposes a new independent regulatory body for IndonesiaOs electricity sector, in particular for investment planning, procurement, tariff setting, and electrification. A situational analysis and review of stakeholder opinions strongly indicates that the current decision-making structures in the electricity sector of Indonesia are inadequate. The report explains the current context and issues in operations and processes. It provides guidance on how an effective regulatory body can be established, including key tasks, legal aspects, and market design.

Wall Street Journal Best Selling Book "I agree with the points made-and with Ayuk's case for the critical role that OPEC will play in helping African oil products achieve a much-deserved voice in the petroleum industry." -OPEC Secretary-General, H.E. Mohammad Sanusi Barkindo Two decades of negotiating African oil and gas deals have given NJ Ayuk a grasp of the continent's energy landscape that few can match. The American-educated, African energy lawyer serves up generous doses of that insight in his second book, Billions at Play: The Future of Africa Energy and Doing Deals. Serving as a road map for the continent to do a better job of using its vast energy resources to improve its peoples' lives, Ayuk addresses how African countries can use their energy industries as springboards for diversifying and growing their overall economies. In addition, Ayuk shows how African governments and local companies can negotiate better deals with international energy companies and how the continent's countries can use marginal oil and gas fields to develop domestic energy industries that, once strong, will compete globally. Questions posed and answered: Why Africa's fledgling natural gas resources can allow the continent to emerge as a key global player in the industry What changes African countries can make in order to become attractive investment destinations The role that access to reliable, sustainable, and affordable power can play in the acceleration of economic growth Why and how American energy companies should stop curtailing their investments in Africa And why the continent's energy industry needs more women The book's underlying theme is that too often, natural resources create wealth for foreign investors and a select group of African elites while everyday people (and in turn, African economies) fail to benefit. While it is easy to see that there is a lack of local participation in African projects and an ongoing challenge in securing necessary investment, we also need to understand our role in this. We have to understand the importance of creating enabling environments with attractive fiscal terms for local and foreign investors, the role of stronger local content policies in ensuring more local participation in the sector, and the weight government and political uncertainty carries in moving projects forward. "It's up to Africans to fix Africa," writes Ayuk. This statement can be considered a living theme throughout the book as he encourages that local companies and governments have to enter into collaborative agreements rather than passive engagements with IOCs and majors. "[We need] investors who show that they want to fully participate with us, by coming in and building long-term sustainable businesses that last and make a profit, create jobs and further development." If you're ready to dive headfirst into accessing a frank analysis and examination of the African energy landscape and how Africans can begin to fix Africa, jump into the pages of Billions at Play.

A unified theory of conservation that addresses the broad problem of conservation, the principles that inform conservation choices, and the application of those principles to the management of the natural world. The conservation of natural resources, like that of any other asset, involves trade-offs. Yet, in a world faced with the harsh realities of climate change, crafting the right environmental policies is an increasingly urgent task. In Conservation, Charles Perrings and Ann Kinzig bring together new research in economics and biodiversity to investigate conservation decisions and the theory behind them. Perrings and Kinzig apply the concept of conservation broadly to examine how the principles of conservation apply to the management of the natural world. They demonstrate that the same basic principles serve as the foundation of all rational conservation decisions, from managing financial assets to safeguarding at-risk ecosystems. Whether someone is deciding to hold or dispose of a stock or whether to exploit or preserve a natural resource, they are better off choosing to conserve a resource when its value to them, if conserved, is greater than its value when converted. The book also considers the context of such conservation decisions. Just as national tax rules influence choices about financial investments, environmental regulations within countries, and environmental agreements between countries, impact the decisions regarding natural resources. Building on their basic theory of conservation, Perrings and Kinzig address key issues in the field of environmental economics, including the valuation of ecosystem services and environmental assets; the limits on the substitutability of produced and natural capital; and the challenges posed by the often weak markets for ecosystem services oriented toward the public good. They also address the problem of scale: while decisions might be easier to make at the local level, many conservation policies need to apply at either the national or international level to succeed. Written by experts from both social and hard sciences, this book presents a unified theory of conservation and provides a model for a more effective way to approach the vitally important issue.

Water is a basic human need and a scarce commodity with increasing value to farmers, industries, and cities in an urbanizing world. It is unpredictable in supply and quality, difficult to contain or direct, and notoriously difficult to manage well. Several trends-climate change, the endurance of widespread global water poverty, intensifying competition among rival uses and users, and the vulnerability of critical freshwater ecosystems-combine to intensify the challenges of governing water wisely, fairly, and efficiently. The twenty-seven chapters in The Oxford Handbook of Water Politics and Policy address such issues over the course of seven thematic sections. These themes reflect familiar frameworks in the water policy world, including water, poverty, and health; water and nature; and water equity and justice. Other sections look at emergent and contentious policy arenas, including the water/energy/food nexus and management of uncertainty in water supply, or connect well-established strands in new ways, including sections on water tools (water price and value, supply and demand, privatization, corporate responsibility) and issues surrounding transboundary waters. This volume conceives of water as a global issue, and gathers a diverse group of leading scholars of water politics and policy.
