* Stephen Bradforth * Do you believe there actually is an energy crisis? * * Intend to engage in shaping energy future * Concerned but powerless * Not a big deal – it will take care of itself * * The rush for the remaining planetary oil and gas resources and decisions on cutting carbon emissions versus economic growth will define 21st century geopolitics, the condition of our planet and, quite possibly, whether there is sustained peace or a new cycle of world wars. Decisions about the energy supply will inevitably determine the quality of life for us all. * The goal of this freshman seminar is for you to be armed with sufficient tools to understand the science behind alternative energy sources, what is possible and what is not and who to believe so you can help shape solutions to this defining issue for our century. * IS92a scenario 1990: 12 TW 2050: 28 TW * "We are like tenant farmers chopping down the fence around our house for fuel when we should be using Nature’s inexhaustible sources of energy—sun, wind and tide. I’d put my money on the sun and solar energy. What a source of power! I hope we don’t have to wait until oil and coal run out before we tackle that.” Thomas Edison, 1931 * Renewables 2%: Biomass and waste 62% Wind 22% Geothermal 11% Solar 1% Tide and Wave 0% excluding hydro Hydro 16% Nuclear 16% Gas 20 % Coal 40% Oil 7% • Fossil fuels are still used to generate 67% of the electricity in the world. • We are on downward side of global oil production and oil prices are now incredibly sensitize to any political situation, driving recessions and prices of food • Climate change from CO2 production is a threat to our way of life (at least according to scientists…) “I do believe that the issue of global warming has been politicized. I think there are a substantial number of scientists who have manipulated data so that they will have dollars rolling into their projects… I think we're seeing it almost weekly or even daily, scientists who are coming forward and questioning the original idea that man-made global warming is what is causing the climate to change” Rick Perry, Texas Governor and GOP candidate for President “If I compare the downsides of coal versus nuclear, I have to say I'd rather see renewed investment in nuclear power” Prof. Steven Chu, Nobel Laureate, in spring 2008 (well before he became US Secretary of Energy) FOSSIL FUELS Clean Coal ? *Coal *Oil *Natural Gas *Nuclear Fukushima Daiichi Nuclear Power Plant, March 2011 * The world uses 1 cubic mile of oil every year! * from Rubin “Why your world is about to get a whole lot smaller” (2009) “With supply dwindling and demand rising, you can expect scarcity. Scarcity mean high prices. You can expect triple digit oil prices in the near future. Yes, that means price at the pump is going to go up. Count on it. In the US, that should translate into as much as $7-per gallon gasoline…. But it will also hurt you in lots of ways you may not be thinking about. … Your food in particular is going to cost a lot more – in fact it is already getting more expensive all the time. The stuff you burn on your car is the same thing the farmer in Iowa needs to plant and harvest corn. It is the same stuff that powers the trucks and planes and ships that move everything around, the same stuff that is used for the petrochemical industry that produces our plastics and pharmaceuticals. …. Some difficult choices lie ahead.” *And he’s not even considering oil and natural gas contribution to electricity supply!

But clotheslines are un-American! In the United States, 92% of single family homes had a dryer in 2005. 80% of US households use a dryer for between 2 and 9 loads per week. Less than 4% of Italian households own a dryer.
