Road Map to a Sustainable Future
Dr. Kelly KissockDepartment of Mechanical and Aerospace EngineeringUniversity of Dayton
Sustainability What is “sustainability” and why is
everybody talking about it? This presentation is about
• Something that is unsustainable• Why it is important, and • What we can do about it
Hint: it’s the central challenge for your generation and the next 100 years.
What on Earth Are These?
World Energy Use
World Population
World Economic Output
Converting Heat to Work
Since pre-history we knew how to:
Work Heat
Industrial Revolution to:
Work Heat
Newcomen’s Steam Engine
~1712
Revolutionary Change
Transforms economy: textile production increases 150 fold and prices drop 90%
Transforms place: cities grow from 5% to 50%
Transforms family: parents leave home to work
Redimensions world: steam ship and railroad
Technology and population explode
Economic Explosion From 1700-
2000, per capita US/Europe income grows from $600 to $18,000 per year
Increases 30x!
Energy Revolution Creates Modern World
Single Most Important Event in Human History
We’ve Come a Long Way… Newcomen’s steam engine: 0.5% Watt’s steam engine: 1% Gasoline engines: 30% Coal Rankine cycles: 35% Turbines: 40% Diesel engines: 50% Combined-cycle turbine/Rankine engines:
60%
But Energy Conversion Largely Unchanged… 1. Use hydrocarbon fossil fuels
2. Employ combustion to release heat CH4+2 (O2) = CO2+2 (H20) 3. Convert heat to work via thermal
expansion
84% Of World Energy From Fossil Fuels

Extreme Oil
“Oil sands and offshore drilling are both symptoms of the same problem: We’re running out of easy oil.”
Simon Dyer
Canada’s Oil Sands
Total resource ~ Saudi Arabia #1 source of imported oil for US (22%) GHG production 5% - 15% greater than domestic oil Surface mining (20%):
• Strip earth’s surface for black goo called bitumen; 2 tons of sand / barrel oil• 1 barrel bitumen generates 500 gallons of liquid tailings• Tailing ponds cover 50 square miles; 3 million gallons/day leak into surrounding watershed• 1,600 waterbirds died in a single tailing pond
In situ mining (80%):• Inject natural gas-heated steam into wells to drive bitumen to surface• Blend bitumen with natural gas liquids to transport and process
Deep Water Drilling Gulf of Mexico
• 6,000 wells• Progressively deeper water • Deepwater Horizon: 5,000 ft

output (U.S. has 2% of world oil resources)

US Energy Efficiency• National Lighting and Appliance Efficiency Standards
• Initially signed by President Reagan in 1987, updated many times since
• "Standards have been a bipartisan energy policy success story stretching across four decades and five presidencies.“
• “Existing standards reduced U.S. electricity use by 7 percent in 2010 and 14 percent by 2035 as consumers and businesses purchase new products compliant with the latest standards”
• “Updated standards by 2015 would reduce 2035 electricity use by another 7 percent.
• “A typical household's total electric bill over this period would be about 33% higher absent efficiency standards.”
• “The cost of more efficient products pays back in lower utility bills within about 3 years, with net benefits outweighing costs by 4 to 1.”

A Cincinnati-area Ikea store will use a 128,000-square-foot array of solar panels installed on its roof to light the store's lamps, the Cincinnati Business Courier reports.
The 344,000-square-foot West Chester store is Ikea's 14th in the U.S. to be outfitted with solar panels, and 23 other locations are getting them as well, the newspaper reports. In West Chester, the array has a 1,026-kilowatt system made with 4,186 individual panels, the newspaper reports.
The 1.3 million kilowatt hours of electricity that the panels are expected to generate each year is the equivalent of reducing 1,014 tons of carbon dioxide, or taking 180 cars off the road, the newspaper reports.
