“Let’s Define New Unit of Energy”Energy=Power x Time
“1 Unit” =1000 Megawatts of electric power for 1 yr
“A typical large power plant”
ABOUT: 0.1 Quadrillion BTU’s
2200 Megawatt thermal energy for one year
9 million Megawatt-hrs electricity
15 million barrels of oil or ~50 super tankers per yr
3 million tons of coal ~ 36500 car loads per yr (train/day)
90 billion cubic ft of Natural gas per yr (~1 cubic mile)
1 ton Uranium per yr (about a 15”x15”x15” cube)
Energy for about 300,000 People in US for a year

Let’s Look at Renewables!
They’ve been a goal for a long time!
They get a lot of political play; it’s politically correct!
They would reduce Greenhouse gases vs coal/oil
They won’t run out!
Can they save us?
Can they eliminate dependence on foreign oil?
![Page 15: What is a Quadrillion?. Reality vs Promises (Science vs. Political Science) Dr James Smiley Understanding the Energy Crisis](https://reader030.vdocuments.us/reader030/viewer/2022032523/56649d935503460f94a7a111/html5/thumbnails/15.jpg)
State of the Union (Who said it? When?)
I urge the energy measures that I have proposed be made the first priority of this session of the Congress. …..They will prevent the injustice of windfall profits for a few as a result of the sacrifices of the millions of Americans.
This must be the year in which we organize a full-scale effort to provide for our energy needs through the 21st century. Let this be our national goal: the United States will not be dependent on any other country for the energy we need
….we plan to spend $10 billion in Federal funds over the next 5 years. That is an enormous amount. But during the same 5 years, private enterprise will be investing as much as $200 billion-- and in 10 years, $500 billion--to develop the new resources, the new technology, the new capacity America will require for its energy needs in the future.
Richard Nixon’s State of Union Address 1974
![Page 16: What is a Quadrillion?. Reality vs Promises (Science vs. Political Science) Dr James Smiley Understanding the Energy Crisis](https://reader030.vdocuments.us/reader030/viewer/2022032523/56649d935503460f94a7a111/html5/thumbnails/16.jpg)
State of Union Address (Who said it? When?)
… our country finally has a national energy policy:
The windfall profits tax on crude oil has been enacted, and a massive investment in the production and development of alternative energy sources; Solar energy funding has been quadrupled, solar energy tax credits enacted…. Ethanol production has been dramatically increased, an amount that could enable ethanol to meet the demand for 10 percent of all unleaded gasoline;
..it is essential that the Nation reduce its dependence on imported fossil fuels and complete the transition to reliance on domestic renewable sources of energy,…
…first step towards widespread introduction of renewable energy sources and established an ambitious national goal for the year XXXX of obtaining 20 percent of this Nation's energy from solar and renewable sources. As a result of these policies and programs… investments in renewable energy sources have grown significantly.
Jimmy Carter State of Union Address 1980

“For a successful technology, reality must take precedence over public relations, for nature cannot be fooled.”—Richard Feynman
Energy Density is very low!
One elephant and 100,000 mice have about the same biomass. Which do you want to try to harness to move a railcar? It’s possible, but how practical?
It’s the ENTROPY!
Why so little progress?

Conservation: Must be part of any plan
Some conservation in 2% growth
Doing pretty good! (Next chart) We need to do more!
Cars about 90 units. 10% increase in CAFÉ
saves 9 units when all cars converted (~10yrs)
Reduce our standard of living? Competitive economy requires abundant energy
World energy demand is growing! (Without us!)
Conserve yes, but can’t save out of the crisis!

Why growth in demand?
China, India, Brazil(CIB) 3 billion people
United States 300 million (1/10th)
China, India, Brazil ~1200 kwh/capita
USA ~12000 kwh/capita
When CIB usage goes from 1200 to 2400 kwh/capita,
we would have to go “0” to keep world demand constant!
CONCLUSION: Conservation yes! But we can’t save our way out of this!
![Page 27: What is a Quadrillion?. Reality vs Promises (Science vs. Political Science) Dr James Smiley Understanding the Energy Crisis](https://reader030.vdocuments.us/reader030/viewer/2022032523/56649d935503460f94a7a111/html5/thumbnails/27.jpg)
Wind PowerFuel is free, renewable, non-polluting, it’s relatively simple!
But: Wind Power is Intermittent (20 to 40% capacity factor)
40 to 70 square miles (3000 turbines) for 1000 MW
But land may still be useable-pasture/crops/factories…
Diffuse energy creates integration/synchronization issues
Often not produced where needed-transmission
Not grid friendly, need storage or Coal/Nuclear backup!
Is it environmentally acceptable? On mountain peaks? Near population?
Do as much as possible when feasible and economical.

Solar Power (World total installed about “16 units”-delivers about “4 units”)
Lots of it, fuel is free, conceptually simple, passive
But: Photovoltaic very costly per megawatt, high maintenance
Solar Thermal costly-need mirrors + heat sink (in the desert?)
Doesn’t work night/cloudy days, capacity factor less than 25%
Energy density extremely low- 40 square miles for 1000MW
Prime locations Southwest desert-far from users
Not Grid friendly, need storage or coal/nuclear backup
Home owners get 30% Fed tax credit
Best use-small scale passive home heating, hot water, remote areas

HYDROELECTRIC
Ideal for electric generation, very cost effective, no carbon dioxide emission, relatively simple.
But: Water distribution diffuse but nature concentrates for us
Not many remaining opportunities to exploit
Environmental concern? – damming of wild rivers?
Useful storage option where available-i.e. pump station
It’s great, use as much as possible, but will be limited to about 5% of total needs (can we use tides?)

GEOTHERMAL
Great source of zone heating and electric power where available. (Like Iceland)
Large heat source deep in earths core, hard to get at, hard to extract large quantities
Few accessible supplies-need both hot rocks and water
There is a 50 degree F heat sink 10 feet down! How to use it?
Do whenever feasible, but NOT readily available
Possibilities? Maybe!

It’s an attractive concept!
It’s Renewable-can be replenished
Plants take Carbon Dioxide back out of the air
But: Uses a lot of land, Competes food supplies
One acre of corn provides 40 or 50 gallons of Ethanol
May use more energy than produced?
One “unit” takes area greater than Rhode Island
Burning wood, converting corn or soy beans into ethanol, use vegetation to make diesel fuel, algae into diesel!
Biomass
Not a good solution!
![Page 39: What is a Quadrillion?. Reality vs Promises (Science vs. Political Science) Dr James Smiley Understanding the Energy Crisis](https://reader030.vdocuments.us/reader030/viewer/2022032523/56649d935503460f94a7a111/html5/thumbnails/39.jpg)
OIL/GASOLINE Provides 95% of Transportation, supports many Industrial Products, Transportation infrastructure is in place
But: High carbon dioxide emission
Cost rising rapidly
Supplies limited- peak oil? Oil shale possibility-costly
We need to import large amounts, economy vulnerable
We’re vulnerable to “blackmail with many dollars going to our “enemies”
Use for Transportation and Industrial Production. Drill-will need all we can get-Increase supplies!
![Page 40: What is a Quadrillion?. Reality vs Promises (Science vs. Political Science) Dr James Smiley Understanding the Energy Crisis](https://reader030.vdocuments.us/reader030/viewer/2022032523/56649d935503460f94a7a111/html5/thumbnails/40.jpg)
Gap in Oil supply and need
![Page 42: What is a Quadrillion?. Reality vs Promises (Science vs. Political Science) Dr James Smiley Understanding the Energy Crisis](https://reader030.vdocuments.us/reader030/viewer/2022032523/56649d935503460f94a7a111/html5/thumbnails/42.jpg)
NATURAL GASProvides most of the home and commercial heating(cheapest option), infrastructure in place, domestic supply, easily transported. High energy content.
But: Upward pressures on price/demand
Rapid growth in use for electrical generation; a more expensive option
Usable for transportation, but need major infrastructure
Available supplies should be used for home and commercial heating. Avoid excessive cost growth!

Coal It currently provides nearly 50% of our electric power-lowest cost. We have domestic supply.
(Remember when it was used for heating and transportation?)
But: High Carbon dioxide emission
Mining and transport dirty and risky
Environmental impact-strip mining, emissions
Reality! Must remain a major energy source; probably more than current 50%. Invest in “clean coal technology”

Nuclear PowerProvides 20% of our electric power; safe, clean, green, Equals coal with lowest electricity fuel cost.
But: No new plants for 20 years
Waste storage an issue-political?
New plants have high initial construction cost
Public acceptance
Nuclear must be a major source of future energy . Can also be used for producing water and hydrogen. Can breed new fuel when needed!

World Reserves! View of Options
Oil-Use 2500 Units of Oil = ~40 billion Barrels/yr
Reserve is ~1300 billion Barrels =~35 to 50 years
Oil sand/shale maybe ~ 30 years more-expensive?
Coal-Use 1800 Units= 3 millions tons of coal
Reserve is ~ 900 billion tons = 200 to 300 years
Natural Gas-Use 1300 Units = 3Trillion Cubic Meters
Reserve is ~ 180 trillion Cubic Meters=60 to 80 years
Uranium- Use 400 Units
Reserve is ~ 200yrs to >>1000’s yrs (with breeding)

SummaryCoal must remain be a major source of our electricity.
Fix the CO2
Nuclear energy must become big player-Open Yucca, reprocess
Oil will be in Short Supply! Costs going up!
Use for transportation/industrial products
Natural gas should be used for home and commercial heating
Wind do as much as practical, develop storage
New capacity likely less than the “20 unit”/yr growth? (60,000 turbines/yr)
Solar and geothermal when economical-will be small players!
Biomass is wrong approach except in special situations
![Page 53: What is a Quadrillion?. Reality vs Promises (Science vs. Political Science) Dr James Smiley Understanding the Energy Crisis](https://reader030.vdocuments.us/reader030/viewer/2022032523/56649d935503460f94a7a111/html5/thumbnails/53.jpg)
Conclusion
Do renewables when cost effective. They can reduce CO2
Renewables will not be major player in reducing oil dependence
Solar –costly, diffuse-best use-home heating/hot water
Wind viable, can help, but limited and not grid friendly
Bio-mass small player, doesn’t make sense
Making renewables focus is not reality
Obscures the hard choices
Coal & Nuclear will be the major players-do them right!
Oil / Gas will be scarce, prices will go back up! Domestic Drilling

Goal/Purpose of talk
1. Educate public about our energy crisis; how big is the problem, how world energy demand effects it, …Put it terms that are more understandable
2. Show what options are valid/which are not, based science, not politics!
3. Put current political posturing/pandering on energy in perspective
4. Briefly discuss pros and cons of the different options Petroleum, coal, wind, solar, nuclear, hydro, et al
5. This is not a pro nuclear talk, but conclusion is that we should pursue most options but coal and nuclear are only viable solutions for foreseeable future.
