No notes for slide. Detailed answers: 1. Use the Internet or other resources to chart the development of an energy technology, from its earliest beginnings to the present day. Did the roots of this technology first emerge prior to the start of the industrial revolution? If so, how? If not, when did the technology first emerge? In what ways did the industrial revolution accelerate the growth of the technology?

More recently, what has been the impact of the information age e. For example, for wind energy, the roots of the technology predate the industrial revolution, dating back to the middle ages in Europe and earlier to use of wind for grinding grain in China and the Middle East. The industrial revolution made possible metallurgical techniques, which in turn enabled the precision fabrication of turbine blades, electrical components, etc.

Since the s, information technology has been used computationally to improve the shape of the turbine blades or operationally to integrate electricity from the turbine into the grid.

Also, solar drying of clothes and food has been practiced since antiquity. The industrial revolution accelerated the growth of solar energy by making possible metallurgical techniques, which in turn enabled the precision fabrication of experimental solar-powered, steam-driven devices starting in the late s.

They also made possible home-sized solar water heating systems for 2. Since the s, information technology has been used computationally to control the manufacture of solar panels, or to operate tracking systems that optimize the position of solar panels relative to the sun.

Note to instructors: it may be preferable to provide the students with the raw data for the three countries used in this exercise, if you wish to save them time on the data gathering and focus on the calculations and analysis. Solution: From studying the accompanying graphs, it is clear that the trend in the United Kingdom more closely resembles that of the United States than that of China. This is different from China, which saw dramatic reductions in energy and CO2 emissions per unit of GDP between and , although these are perhaps slowing after On the population side, energy consumption per capita is slightly up for the United Kingdom and the United States and CO2 emissions per capita are slightly down for the period in question.

This suggests that both countries are reducing the amount of CO2 per unit of energy consumed. China is much lower in per capita measures than the other two countries, but is seeing an upturn in both since , so that it appears that in the most recent years, China is moving in a different direction than the other two countries.

Since or so, China is growing a much larger middle class, so it is not surprising that energy and CO2 might turn upward in this way. In general, the shape of the figures varies little whether one compares the three countries in terms of per unit of energy or per unit of CO2 emitted. The most profound change has been the reduction in energy and CO2 per unit of economic activity in China.

Compared to this trend, all other measures have not changed as much. Figures to accompany Problem 1. The country of Fictionland has 31 million populations and consumes on average Calculate the HDI for Fictionland. Is it above, below, or on a par with these other countries? Part b : Fictionland lies below the curve for the other countries. Regression analysis of population, economic, and environmental data for countries of the world. For this exercise, download from the Internet or other data source values for the population, GDP in either unadjusted or PPP form, energy consumption, and land surface area of as many countries as you can find.

Then answer the following questions: a. From the raw data you have gathered, create a table of the countries along with their GDP per capita, energy use per capita, and population density in persons per square kilometer or square mile. In part a , did your data source allow you to include figures for all three measures for all the major countries of all the continents of the world? If not, what types of countries was it not possible to include, and why do you suppose this might be the case?

Using a spreadsheet or some other appropriate software, carry out a linear regression analysis of energy consumption per capita as a function of GDP per capita. Produce a scatter chart of the values and report the R2 value for the analysis.

One could also speculate that population density will influence energy consumption, since a densely populated country will require less energy to move people and goods to where they are needed. Carry out a second regression analysis of energy consumption per capita as a function of population density. Discussion: Based on the R2 value from parts c and d , how well do GDPpc and population density predict energy consumption? What other independent variables might improve the model? Briefly explain.

Given the global nature of the world economy, what are some possible flaws in using energy consumption figures broken down by country to make statements about the relative energy consumption per capita of different countries?

Solution: a. Preprocess: from the raw data given, create a table of the countries to be included in the model and the dependent and independent variable values for each countries. Note: for simplicity and ease of grading, please do not augment the data set with figures that you find in other sources. Calculate these variables by dividing the total energy consumption by the country population, total GDP by population, etc. Table not shown for brevity.

Note that in part a not all countries are included. What can you say about the countries which are typically left out of this list? A one- to two-sentence answer is fine. We also may infer that these are third-world countries where energy consumption, GDP, and population estimates may not be as readily available.

Other answers also accepted. Also, give the R2 value and plot a scatter chart with curve fit. Discussion: Based on the R2 value from part d , how well do GDP and population density predict energy consumption?

You can describe these variables and explain in words how they might help, but you do not need to carry out any calculations 1 page maximum. Population density is not an effective predictor with a very low R2 0. Hong Kong and Singapore. Discussion: Given the global nature of the world economy, what is a possible flaw in using energy consumption broken down by country to make statements about energy consumption per capita?

One paragraph maximum. ANSWER: Energy consumption of a country does not necessarily mean that all the energy was used to make goods or provide services by the people of that country. For example, China produces many manufactured goods that are subsequently consumed by citizens in the United States. So, this may make Chinese citizens appear to be consuming more energy, when it should in reality be attributed to American citizens.

Similar arguments could be made for other products, including oil, which can require an energy intensive process to extract and refine before exporting to other countries. What are the equivalent amounts in EJ? Solution: Multiply each value by 1. Thus, the values are for the four sectors, respectively: What are these same values converted to quads?

Solution: Multiply each value by 0. Thus, the values are for the four countries, respectively: Create a list of the four countries, ranked in order of decreasing carbon intensity per unit of energy consumed.

Solved here in are metric units.

Energy Systems Engineering: Evaluation and Implementation

Book description: The defining guide to energy systems engineering--updated for the latest technologies. Fully revised throughout, Energy Systems Engineering , Second Edition discusses fossil, nuclear, and renewable energy sources, emphasizing a technology-neutral, portfolio approach to energy systems options. The book covers major energy technologies, describing how they work, how they are quantitatively evaluated, their cost, and their benefit or impact on the natural environment. Evaluating project scope, cost, energy consumption, and technical efficiency is clearly addressed. Example problems help you to quantify the performance of each technology and better assess its potential. Hundreds of illustrations and end-of-chapter exercises aid in your understanding of the concepts presented in this practical guide.
