Road Map to a Sustainable Future Dr. Kelly Kissock Department of Mechanical and Aerospace Engineering University 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 Economic Output World Population 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!

Solar Pricing Recent Ohio News West Chester Ikea plugs in solar panels Business First Date: Wednesday, January 25, 2012, 7:36am EST 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.
