The rather specialized field of solar and infrared radiation measurement has become more and more important in the face of growing demands by the renewable energy and climate change research communities for data that are more accurate and have increased temporal and spatial resolution. Updating decades of acquired knowledge in the field, Solar and Infrared Radiation Measurements details the strengths and weaknesses of instruments used to conduct such solar and infrared radiation measurements.

Topics covered include:

• Radiometer design and performance
• Equipment calibration, installation, operation, and maintenance
• Data quality assessment
• Methods to use measured data to estimate irradiance for any surface

With a broad range of content that will benefit students and more experienced readers alike, this resource serves as a primer and technical reference that presents the basic terminology and fundamentals for resource assessment. It explores the history of solar radiation instruments and addresses direct normal, global, diffuse, and tilted measurements, as well as the characteristics of instruments used for these measurements. The authors consider methods of assessing the uncertainty of solar measurements and then cover albedo, infrared, net, and spectral irradiance measurements and instrumentation. The book devotes a section to other meteorological instruments, and another to the basics for installing and operating a solar monitoring station. Appendices include information on solar resource assessment modeling and satellite-derived irradiance, along with other useful material.

The paper 'Operating and Planning Electricity Grids with Variable Renewable Generation: Review of Emerging Lessons from Selected Operational Experiences and Desktop Studies' focuses on analyzing the impacts of variable renewable energy on the operation and planning of the the power system (mostly, generation system). It is aimed at informing stakeholders in power utilities, regulatory bodies and other relevant audiences, on the fundamentals of technical challenges and approaches to operate electricity grids with renewable energy. It covers renewable energy as a whole, but in particular, focusses on wind and solar energy. It also presents three case studies of countries, including China, Gemany and Spain.

The total worldwide installed capacity of wind and solar projects is growing rapidly, and several countries are noticing increased penetrations of wind and solar in their electricity generation mix. In addition to operating experience being gained from adding wind and solar capacity, several grid integration studies have been performed that assess potential grid and operating impacts from adding higher amounts of wind and solar capacity. Perhaps just as important, the electric power industry and those that conduct research on grid integration have not found a maximum level of variable generation that can be reliably incorporated, and it is clear that it is as much an economic question (how much cost in additional reserves or grid impacts is acceptable) as a technical question regarding grid operators ability to adapt to the new challenges.

In addition, while their contributions to capacity or 'firm' power and associated costs are different from those of conventional power sources, variable renewable generation technologies can contribute to long-term system adequacy and security. The paper describes on the contribution of variable power sources to long-term supply adequacy requirements, i.e. how much sources like wind and solar power contribute to 'firm supply' in a system. It also describes methods to find out to what extent they contribute and at what cost. It also aims at providing indicative answers to how costs to system operations be determined and when and how an integration study be done to estimate the short-term reserve costs of renewable energy.

The concepts in the paper should be of interest, especially to grid planers. For grid operators, the paper summarizes a menu of strategies that the operational practices and desktop research tell about managing wind in a system at different levels of penetration. It also elucidates available strategies, amongst other crucial questions of operational impacts and challenges that operators need to be aware of, to integrate variable generation.

A solution to the climate and energy crisis
The reversible fuel cell (RFC) described in this volume stores solar energy and thereby makes it continuously available. This can make the building of energy-free homes and all electric transportation a reality. The foldout drawing at the back of this book also describes the detailed design of the world’s first 1,000 megawatt solar-hydrogen power plant.

How is this possible?
Our planet receives more solar energy in an hour than humans use in a year. In fact, 5% of the Sahara could meet the total energy requirement of mankind. This energy can then be stored and transported in the form of hydrogen.

Converting from an exhaustible energy economy to a clean, free, and inexhaustible one
In this timely book, author Béla Lipták explains why a solar-hydrogen economy is technically feasible and cost-effective. He first outlines existing conservation technologies and renewable energy processes as well as evolving technologies, such as energy-free homes, roof shingle solar collectors, and RFCs. He goes on to discuss energy optimization techniques that could reduce the global energy consumption by one third and finally presents the detailed design of a full size solar-hydrogen power plant.

It is time to harness the power of solar energy
With global energy consumption quadrupling in the last fifty years and atmospheric carbon dioxide reaching the highest level ever recorded, now is the time to prevent further damage to the planet and ensure the survival of human civilization. It is debatable how much time we have before our fossil and uranium deposits are exhausted. It is also debatable how much climate change we can live with or how much of our economic resources should be devoted to stabilizing and reversing mankind’s growing carbon footprint. What is not debatable is that our resources are exhaustible and that we must not give reason for our grandchildren to ask, "Why did you not act in time?".

The creation of a flexible, efficient, digitized, dependable and resilient power grid may well be the best route to increasing energy efficiency & security, as well as boosting the potential of renewable & distributed power sources. However, there is still much confusion about the nature of the Smart Grid: What is it? What work needs to be accomplished in order to make it a reality? How will it benefit the drive to diversify energy resources?

This book covers Smart Grids from A-Z, providing a complete treatment of the topic, covering both policy and technology, explaining the most recent innovations supporting its development, and clarifying how the Smart Grid can support the integration of Renewable Energy resources.

Among the most important topics included are smart metering, renewable energy storage, plug-in hybrids, flexible demand response, strategies for offsetting intermittency issues, micro-grids for off-grid communities, and specific in-depth coverage of wind and solar power integration. The content draws lessons from an international panel of contributors, whose diverse experiences implementing smart grids will help to provide templates for success.

If we intend to undertake a meaningful overhaul of the way the world uses energy resources, we ignore grid management issues at our peril. Ultimately, this important book examines what the integration challenges are, what technology and policy needs to be in place in order to support uptake, and what The Smart Grid can do to enable solutions.

• Provides critical information on the technological, design and policy issues that must be taken into account to ensure that the smart grid is implemented successfully
• Demonstrates how smart grids can help utilities adhere to increased renewable portfolio standards
• Provides examples of successful microgrid/smart metering projects from around the world that can act as templates for developers, operators and investors embarking upon similar projects
