The overall objective of this class is to provide an
introduction to electrical generation and power
distributions systems including renewable energy.
1. Discussion of the electrical power industry and
drivers for change.
2. Review of electrical circuits and electrical power
distribution systems
3. Review of Solar Power Generation
4. Wind Power Systems
5. Other Renewable Energy Systems
6. Smart Grids, Energy Storage, Demand Side
Management

Additional Objectives
Some understanding of the complexity of the
problems.
A. The size and scope of the electrical energy system.
• The complexity of the Grid and problems of reliability.
B. The coupling to the standard of living and population
growth.
C. The complexity of the climate change forecasting
D. Economic Issues
E. The importance of the Political And Regulatory
Structures.

Course Operations
• There will be reading of about 10 to 15 pages a day
required on the average if we are to cover the
material in the book.
• There will be a short quiz every Monday morning.
This will be graded at either zero or ten, with 10
given for right answers only on numerical problems.
• There will be 2 or 3 1-hour tests worth 100 points
each. The third test will be given if we have time
and if it looks likely to be helpful .
• The final exam will be worth 200 points.

Course Operations
• There will be a term paper required of about 10
pages to allow you to go beyond the text into the
literature on a topic of interest to you. This paper
will be worth 50 points
• The final grade is not taken from a straight sum of
all the grades above but will be at least partly a
subjective evaluation of your overall performance in
the class. For example: a very strong final may
compensate for a weak hour test or few bad
quizzes. A really strong term paper will also lift a
grade etc.

Energy Consumption in the US since 1780
This Model is Typical for all of the world
Principal Uses of Energy
•
•
•
•
•
•
•
•
Transportation – Air, Sea, Land – People & Goods
Lighting – Home, Industrial, Outdoor
Heating / Cooling – Home, Industrial, Civil
Food Production / Preparation / Preservation
Mechanical Work – Factories, Mining, Construction
Communications – Voice, Video, Data
Entertainment
Practically everything else we do!!!
Most Involve the Generation and Use of Electric Power
WHY?
A New Set of Drivers Has Emerged
• Population growth – 10 B people by 2050 (7B now)
• Economic development in undeveloped /
underdeveloped parts of the world –
2B without electric power today
 Linkage between cheap power and standard of living

• Need for environmental responsibility

CO2 33%, SO2 75% , NOx 33%, 25% particulates (heavy
metals, Hg etc.) from US Electric Power alone
• Finite & diminishing fossil fuel assets over the long
term - a long term strategic issue for US
• Integration issues with other utility segments (water,
sewage, telecom, etc.)

CO2 Concentrations over Time
1. This is a report worth reading if you are interested in the effects of CO2 on
Climate change.
2. CO2 levels hit new peak at key observatory - CNN.com
www.cnn.com/2013/05/10/us/climate-change
May 14, 2013 - Scientists for the first time measured an average concentration of
carbon dioxide of 400 parts per million in Mauna Loa, Hawaii.
Carbon dioxide levels can be seen climbing steadily in Scripps data from the last 55 years.

Homework
1. Find data that might explain why the temperature
is approximately constant from 2000 to 2010.
2. How long would it take to bring the CO2 back to
the level of 1960 if we had no emission starting
tomorrow?
A. Some partial but insufficient information
In 1780 CO2 ≈ 280ppm
In 2009 CO2≈ 387ppm
3. What are some of the implications of the global
temperature rise that might affect you?
