- This doesn't make sense/I think it is wrong. Unimpressed that I just payed for this service and this is the first answer that I came across.
- The answer is correct. The heat rate is the amount of energy used by an electrical generator or power plant to generate one kilowatthour (kWh) of electricity.
- Step 3 of 5(b)Consider a formula for emission rate of carbon.…… (3)Substitute 6,923.07 for heat rate and 55340 for energy density in Equation (3).
- i think that should be kgC instead of kJC for the units in the final answer
- Step 4 of 5Consider a formula for emission rate of carbon dioxide.…… (4)Substitute 0.09632 for carbon emission rate in Equation (4).
- units are wrong
- Step 5 of 5Consider a formula for average total plant emission rate.…… (4)Substitute for 52% efficient combined plant and for 33% efficient coal plant in Equation (4).Thus, the average total plant emission is reduced to .
- Is there some sort of conversion taking place? Dividing those two numbers results in .2727, not .36 so I'm curious if I'm missing something.
- I am wondering the same thing.
- same thing how they got 64%
- You need to use 0.2673 kgC/kWh given on page 29 of the text. The units give away the wrong number. The coal plant emits 0.2673 kgC/kWh. Using these numbers gets 0.36 and satisfies the cancellation of units to give a percentage.

Renewable Energy (RE) sources differ from conventional sources in that, generally they cannot be scheduled, they are much smaller than conventional power stations and are often connected to the electricity distribution system rather than the transmission system. The integration of such time variable ‘distributed’ or ‘embedded’ sources into electricity networks requires special consideration. This new book addresses these special issues and covers the following: The characteristics of conventional and RE generators with particular reference to the variable nature of RE from wind, solar, small hydro and marine sources over time scales ranging from seconds to months The power balance and frequency stability in a network with increasing inputs from variable sources and the technical and economic implications of increased penetration from such sources with special reference to demand side management The conversion of energy into electricity from RE sources and the type and characteristics of generators used The requirement to condition the power from RE sources and the type and mode of operation of the power electronic converters used to interface such generators to the grid The flow of power over networks supplied from conventional plus RE sources with particular reference to voltage control and protection The economics and trading of ‘green’ electricity in national and international deregulated markets The expected developments in RE technology and the future shape of power systems where the penetration from RE sources is large and where substantial operational and control benefits will be derived from extensive use of power electronic interfaces and controllers The text is designed to be intelligible to readers who have little previous knowledge of electrical engineering. The more analytical electrical aspects are relegated to an Appendix for readers who wish to gain a more in depth understanding. The book’s flexible structure makes its accessible to the general engineer or scientists but also caters for readers with a non-scientific background. Economists, planners and environmental specialists will find parts of the book informative.

Reflecting its reliance on fossil fuels, the electric power industry produces the majority of the world's greenhouse gas emissions. The need for a revolution in the industry becomes further apparent given that 'decarbonization' means an increasing electrification of other sectors of the economyin particular, through a switch from gasoline to electric vehicles. Of the options for producing electric power without significant greenhouse gas emissions, renewable energy is most attractive to policymakers, as it promises increased national self-reliance on energy supplies and the creation of new industries and jobs, without the safety and political concerns of nuclear power or the unproven technology of carbon capture and storage. Drawing on both economic theory and the experiences of the United States and EU member states, Harnessing Renewable Energy addresses the key questions surrounding renewable energy policies. How appropriate is the focus on renewable power as a primary tool for reducing greenhouse gas emissions? If renewable energy is given specific support, what form should that support take? What are the implications for power markets if renewable generation is widely adopted? Thorough and well-evidenced, this book will be of interest to a broad range of policymakers, the electric power industry, and economists who study energy and environmental issues.
