The reasons for this apparent paradox are varied, and this book provides a deeper and more nuanced understanding of the practical applications of photovoltaics (PV) in modern electricity systems. While the conventional life-cycle assessment (LCA) boundaries as prescribed by the IEA-PVPS provide a consistent methodology for comparing evolving PV technologies, the narrow boundaries exclude many critical downstream energy costs. Similarly, simple cost comparisons of PV versus conventional power sources overlook the significant economic and energy costs of intermittency and grid integration. Yet distributed storage, which could provide potentially valuable network support, is frequently given a low priority by advocates of solar.
Treating PV as an extension of, rather than as a substitute for, the fossil fuel enterprise enables a more productive discussion of PV’s potential role in electricity generation. The sunburnt country of Australia, which has a modern electricity system, is an ideal case study for exploring the potential of solar PV. With a focus on rooftop solar, energy storage, grid integration, and electricity system issues, Energy in Australia offers valuable insights into the practical challenges of solar power. Although many national economies are already confronting a downward trend in energy return on investment (EROI) of oil and gas from both conventional and unconventional sources, the large-scale deployment of low-emission energy sources that lie below a critical minimum EROI threshold may ultimately prove counter-productive.
The Power Makers ’ Challenge: and the need for Fission Energy looks at why using only conventional renewable energy sources is not quite as simple as it seems. Following a general introduction to electricity and its distribution, the author quantifies the reductions needed in greenhouse gas emissions from the power sector in the face of ever increasing world demands for electricity. It provides some much needed background on the many energy sources available for producing electricity and discusses their advantages and limitations to meet both the emission reduction challenge and electricity demand.
By analyzing the three main groups of energy sources: renewable energy, fossil fuels and fission energy (nuclear power), readers can assess the ability of each group to meet the challenge of both reducing emissions and maintaining reliable supply at least cost. It is written for both non-technical and technical readers.
Let the IEA guide you into successful, efficient and effective policies and decisions for accelerating deployment of renewable energy. Learn about the six policy actions that are essential ingredients for your policy portfolio:Alliance Building Communicating Target SettingIntegration in economic policies Optimizing existing instruments and Neutralizing disadvantages on the playing field
This book shows why and how successful renewable energy strategies work. Many recent and actual examples of best cases and experiences in policies--based on literature and interviews--show how policies can best mobilize national and international renewable energy business and the financial institutions, while creating broad support. The book is an initiative of the IEA-RETD, an international agreement between nine countries to investigate and accelerate the deployment of renewable energy deployment.Presents you with a variety of policy options that have been proven to accelerate the deployment of renewable energy technologies Based on experiences around the world at the local, regional and national levelsIncludes the IEA’s ACTION star, a decision-making tool for developing a consolidated renewables policy frameworkFind inspiration in this guide’s depiction of the significant renewable energy developments to date and the many examples of successful policies featured
The book begins by defining energy and then giving examples, such as hoisting a weight, pushing a piston, or boiling a pail of water. Some of the common forms of energy are known as kinetic, thermal, chemical, electrical, radiant, sound, stored, potential, and nuclear. These forms are described and exemplified.
Concern is sometimes expressed that world energy is being "used up." This is a meaningless concern. Here we will evaluate and quantify the world's principal energy usage (food, heat, transportation, and industrial processes), and consider the energy sources which provide this usage. A sensible and economically viable plan is then proposed and described for meeting all our energy needs.
As we consider and examine various energy sources which mankind has available, we easily come to the most dramatic and most important source for a sensible energy policy: direct solar radiation. We would satisfy all U.S. energy requirements if we were able to capture and make use of one hundredth of 1% of all the solar energy intercepted by the earth. This is not a very difficulty thing to do. All we need is creative vision, governmental support, and the determination to become energy independent soon, and our sensible goals will be achieved completely and economically.
