Energy v.
Electricity; What is
the AZ Corporation
Commission
Nancy LaPlaca, J.D.
Advisor to AZ Corporation
Commissioner Paul Newman, Esq.
Arizona Corporation Commission
nlaplaca@azcc.gov
602-542-3682
2. Agenda – Hour One
• What is the AZ Corporation Commission and
why should I care? Bio’s
• Energy v. electricity: emissions from electricity v.
transportation
• Energy: net energy is key
• What about fossil fuel depletion?
• Global warming: what does it mean?
• 4 minute YouTube of Richard Heinberg: 300

3. The AZ Corporation Commission
(ACC) – Why Should I Care?
• The ACC is one of 7 ‘constitutional’ and 13 elected
Public Utilities Commissions (PUCs) in the U.S.
• The ACC has authority over power plants
• Generally, participants at the ACC are the (monopoly)
utilities, the large energy users (such as mines), utility
shareholders…not many public interest participants.
• Bottom line: ACC has enormous authority over
energy policy, and clean energy needs only THREE
votes out of FIVE elected Commissioners….
• See www.azcc.gov for more information…or call our
office 602-542-3682 and come visit us!

13. Net Energy is Key Concept
• Net Energy = the energy left after using energy to drill,
mine, transport, compress, combust, build, etc.
• Also called E-ROI (Energy Return on Investment)
• Energy costs are going to rise: Should we invest in
renewables, with higher capital (building) costs, or
fossil fuel, with increasing fuel costs and high
Operation and Maintenance (O&M)?
• “Externalities” increasingly important: global warming,
water scarcity; also enormous health effects from fossil
fuels we’ve ignored for decades
• Environmental justice issues: local, U.S., global

18. Energy Slaves?
• Fossil fuels are extremely dense form
of energy
• ~8 calories of oil embedded in every
calorie of food delivered
• Oil runs our just-in-time economy
• Renewable energy (solar, wind) not
nearly as dense, not available ‘on
demand,’ difficult to store energy
• We will likely continue to electrify our
transportation system – running a car
on coal-fired power emits less
pollution than gasoline because car
engine is so inefficient.

42. AZ’s Electricity Mix
• Total in-state generation: 25,000 MW
• Total in-state consumption: 16,000 MW
– 50% coal
– ~28% natural gas
– ~22% nuclear
– Less than one-tenth of 1% solar
• 54 MW installed in 2010
• Total in-state solar: ~100 MW
43. Coal, Nuclear, Natural Gas, Solar,
Wind, Solar Hot Water….
• Issues are complex and confusing because different types
of power plants have pro’s and con’s
• Coal and nuclear plants run 85-90% of the hours in a year
• Solar only makes electricity when the sun shines;
however, AZ has the best land in the U.S. for solar
because it is very flat and we have consistent sunshine
• KEY: we don’t include all the life-cycle costs of electricity
generation, such as pollution, acid rain, health effects from
burning coal, possible water pollution from natural gas
drilling etc.
• We are at crossroads on energy policy – what do YOU
think we should do?

51. AZ Imports Most Fossil Fuels
• AZ imports all its Natural Gas and 2/3 of coal
• AZ spent $1.5 billion importing Natural Gas
(NG) for electricity in 2009
– Another $800 million spent on NG for heating
– Shale gas has been a game-changer, brought the
price of gas way down, but ultimately depleting
– During Katrina, cost of NG doubled; also doubled
from 2007 to 2008 when oil peaked at $147/barrel
• AZ spent $500 million in 2007 importing
coal
57. Why doesn’t AZ have more
clean energy?
• Many reasons, but here are a few:
– Monopoly utilities granted geographic territories (APS,
SRP, TEP etc.)
– Large central-station power plants
– Distributed generation is a new player, and solar has
only recently come down in price
– Politics and the corrupting influence of fossil fuel $$$
– Utilities don’t want to give up sales to ‘disruptive’
technologies.
– The more distributed solar, the LESS revenue for
utilities; lost ‘fixed’ costs…
58. Kevin Phillips, Bad Money
From ASPO-USA Conference, October 12, 2009
Financial services increased
from less than 10% to nearly
50% of corporate profits
Manufacturing declined from
60% to less than 10% of
corporate profits
62. “Externalities” in electricity
• Uncounted costs are called “externalities” and include:
– Subsidies
– Air pollution, water use and pollution
– Mercury contamination
– Lost productivity, morbidity and mortality
– Health effects from fossil fuel burning
• 12/08 coal ash spill in TN cost $1.2 billion
• Power plants are big water users: nuclear the most, then
coal; solar PV and wind use zero water; Concentrating
Solar Power can be wet or dry. Wet CSP that uses a
steam turbine uses as much water as a coal plant but
does not pollute the water.
66. National Academy Estimates Criteria*
Pollutants from 406 Coal Plants Cause
$68B/Year Damage
NOTE: CLIMATE
CHANGE DAMAGES
NOT INCLUDED,
ONLY SO2, NOx, PM
2.5 &10
Damages from these plants exceed $500 million a year

67. Coal’s Externalities / True Costs
Coal-fired power plants produce 50% of U.S. electricity.
Coal costs the U.S. $500B annually over its life cycle
(extraction, transport, processing, and combustion)
•$74B in public health burdens in Appalachian communities
•$187.5B from health costs of cancer, lung disease, and
respiratory sickness in other parts of the U.S.
•$29.3B from mercury impacts
•$205B from carbon emissions’ climate impacts on land use,
energy consumption, and food prices
•$18B from the costs of cleaning up spills of toxic waste,
the impact of coal on crops, property values, and tourism
Externalities would raise costs of electricity from coal-fired
plants, from $0.10 / kWh to $0.28 / kWh, shifting it from one of
the cheapest sources of electricity to one of the most expensive.

Hinweis der Redaktion
Society runs on Net Energy—what’s left over after—not on Gross Energy.
5 Large base load generating plants are only about 33-40% efficient. Almost 2/3 of the energy inputs are thrown off as waste, due to the technology itself. Add to that the energy required to DELIVER electricity from point of generation to point of use – line losses – and you can see that our increasingly electrified economy generates a lot of waste.
