Understanding Power vs. Energy: Insights from Claire Leuschen's Presentation

In "Power Tripping 101," Claire Leuschen discusses the critical difference between energy and power, arguing that societal focus often skews towards power. Hydrocarbons are primarily relied on for horsepower, representing 90% of usage due to their reliability and storability, despite America being a top oil importer and exporter. The presentation highlights the complexities of transitioning to alternative energy sources, emphasizing power density, energy density, scale, and cost as four imperatives that influence energy strategies. Enjoy deeper insights into energy myths and real fuels for the future.

  1. Power Tripping 101 Presented By Claire Leuschen

  2. Energy or Power? • “WE DON’T GIVE A DAMN about energy. What we want is power.” • There is a difference between the two.

  3. Hydrocarbons • 90 percent of the horsepower used • Reliable • Can be stored

  4. Oil • US the largest importer • Also one of the largest EXPORTERS • “Terrorist attacks cost so little to perpetrate that attempting to curtail terrorist financing through measures affecting the oil market will not be effective” • The Rand Corporation • Hitting the cap?

  5. -1.8%

  6. Moving Away from Hydrocarbons • Now 20% of electricity generated in America • Nuclear power generated from 1973 to 2008 increased 800% • It will not be fast, easy or cheap

  7. Four Imperatives • Power Density • Energy Density • Scale • Cost • Can the various energy sources satisfy them?

  8. References • Bryce, Robert. Power Hungry: The Myths of "green" Energy and the Real Fuels of the Future. New York, NY: PublicAffairs, 2010.

  9. Questions? • From 1990 to 2007, how has the percent CO2 emissions per capita changed for the U.S.? - a) 72%  b) -1.8%  c) 37% d) 132% • What are the Four Imperatives? • Energy and are different?
