1. List three (3) of the main highlights of the 1980 National Academy of Sciences
(NAS) 'Energy in Transition Report' according to Ronald Bailey. Explain in
a few words what Tom Adams views as the apparent inconsistency of both
too much and too little fossil energy. List three (3) important physical
realities that, according to Vaclav Smil, account for the fact that the
difficulties of shifting away fossil fuels are typically underestimated by
renewable energy proponents.
The 1980 report heavily emphasized conservation, and noted that coal and
nuclear fission were the "only readily available large-scale domestic
energy sources that could even in principle reverse the decline in domestic
energy production over the next three decades."
The 1980 report noted that "more rapid economic growth...implies higher
energy consumption."
The 1980 report also confidently predicted that "technical efficiency
measures alone could reduce the ratio of energy consumption to gross
national product...to as little as half its present value over the next 30-40
years."
The prospects of various nuclear technologies—including fast breeder and
thorium reactors—filled many pages in the 1980 report.
he believes that continued fossil fuel usage is about to cause a climate
catastrophe. At the same time, he also believes that fossil fuels supplies are about
to be exhausted. The book is silent on how to square the apparent inconsistency
of both too much and too little fossil energy.
Neither is Hamilton clear on how much wealth he thinks we should sacrifice to
abate what quantity of carbon emissions.
To the scale of the required transformation,
to its likely duration,
to the unit capacities of new convertors,
2. What are the two 'nonmarket failures' discussed by Robert Bradley? Say a
few words about each. What are the Standing Senate Committee on Energy,
the Environment and Natural Resources (ENEV) priorities for action in
terms of natural gas, hydropower, regulatory reform and nuclear power?
One is analytic failure, in which the outside evaluator’s prescription for
intervention (such as a per barrel “energy security” tax on oil imports or a per
ton “climate change” tax on carbon dioxide emissions) overcorrects or
undercorrects for the “real” problem.

Only pages 1-3 are available for preview. Some parts have been intentionally blurred.

Second, there is government failure whereby even the “correct” analytical
blueprint is altered and violated in the political process.
Natural gas: a game-changing fuelReliable, versatile and efficient, natural
gas is becoming a platform fuel for the Canadian economy; its expansion
should be encouraged.
Hydropower superpower: energy of the past for the future This reliable,
low-emitting source of energy is a key priority for the country and every
opportunity for its responsible expansion must be undertaken.
Regulatory reformThe committee supports the ongoing commitment of
federal, provincial and territorial governments to streamline environmental
reviews while ensuring rigorous environmental oversight, especially for
major projects.
Maintain strong support for Canada’s nuclear industry Nuclear energy
has an important role to play in Canada energy future.
3. In the context of this course, how do we define energy? Work? Power?
Energy conversion processes? Efficiency? Energy Systems? Give an
illustration of how qualitative differences also matter in terms of energy
sources.
Energy
“ability/ capacity to do work”
Work
Force X distance through which that force acts
US: units of foot- pounds
Europe: newton- meters (or joules)
1joule= amount of work done
Power=work done
time takeon=energy used
time taken
energy conversion processes
Processes through which transformation of energy from primary sources to
end uses
efficiency=work done
energy spend work output
energyinput
An energy system is an interrelated network of energy sources & stores of energy
Connected by transmission,distribution Of that energy to where is needed

Only pages 1-3 are available for preview. Some parts have been intentionally blurred.

4. In one sentence, why does Peter Huber argue that wasting energy is not
always a vice? How does he illustrate the 'energy waste' inherent in the
product of a 10-watt laser beam?
It is only by throwing most of the energy away that we can put what's left to
productive use a
He illustrate that people still perfer to use 10-watt laser beam even though it is
not effective power because it is better-ordered photons packed into less space
are worth far more. He points out that people sometimes waste energy to
achieve other purpose (to the contrary, it delivers less, and we waste huge
amounts of ordinary light producing it. It takes big arrays of flash lamps,
mounted around a large gas cavity, to stimulate the emission of the knifelike
laser beam.)
5. What does EROEI stand for? What are the key insights of its proponents?
What is Peter Huber's take on the concept?
EROEI
(energy return on energy invested)
Key point
Never makes sense to burn 2units of energy to extract, unit of energy
Negative EROEI ~ energy bankruptcy
Huber on EROEI
Economic value function of
Distance b/w BTUs & where needed
Quality of available technology to move, concentrate refine and burn BTUs
How neighbors feel about carbon, uranium and wind mills
How densely BTUs packed into moveable pounds
6. What does Jesse Ausubel mean when he refers to the 'decarbonization' of our
economies? What factors explain this 'decarbonization'? What are the main
lessons to be learned from the history of energy transitions according to
Robert Bryce?
.Evolution of energy use
Over time, our economies~
More efficient (better conversion ratios)
Less taste for carbon (decarbonization)
“Decarbonization” matters
C becomes soot or CO2
