Learn moreIn this book, Vaclav Smil argues that power density is a key determinant of the nature and dynamics of energy systems. Any understanding of complex energy systems must rely on quantitative measures of many fundamental variables. Power density—the rate of energy flux per unit of area—is an important but largely overlooked measure. Smil provides the first systematic, quantitative appraisal of power density, offering detailed reviews of the power densities of renewable energy flows, fossil fuels, thermal electricity generation, and all common energy uses.
Smil shows that careful quantification, critical appraisals, and revealing comparisons of power densities make possible a deeper understanding of the ways we harness, convert, and use energies. Conscientious assessment of power densities, he argues, proves particularly revealing when contrasting the fossil fuel–based energy system with renewable energy conversions.
Smil explains that modern civilization has evolved as a direct expression of the high power densities of fossil fuel extraction. He argues that our inevitable move to new energy arrangements involving conversions of lower-density renewable energy sources will require our society—currently dominated by megacities and concentrated industrial production—to undergo a profound spatial restructuring of its energy system.
Vaclav Smil is Distinguished Professor Emeritus at the University of Manitoba. He is the author of forty books, including Power Density: A Key to Understanding Energy Sources and Uses and Made in the USA: The Rise and Retreat of American Manufacturing, both published by the MIT Press. In 2010 he was named by Foreign Policy as one of the Top 100 Global Thinkers. In 2013 Bill Gates wrote on his website that "there is no author whose books I look forward to more than Vaclav Smil."
Daniel Henning is a director, producer, actor, and writer. His work has been seen on HBO, CBS, NBC, ABC, FOX, MTV, Comedy Central, and on stages throughout Southern California. He won a 2017 Telly Award for "Best Writer" for the film version of his play The Tragedy of JFK (as Told by Wm. Shakespeare). As director and writer, his TV and film work includes MTV's Rob Dyrdek's Fantasy Factory and the film Critic's Choice. He won the NAACP Theatre Award for "Best Director of a Musical" for The Wild Party. He is the Founding Artistic Director of Hollywood's The Blank Theatre, winning over 200 awards for his productions, including "Best Production," from LA Drama Critic Circle, LA Weekly, Ovations, NAACP, etc. Henning has been inspirational to thousands of young artists through his creation of The Blank's Young Playwrights Festival (the only professional nationwide competition for playwrights aged nine to nineteen). He directed the first play by 2016 Tony Award Winner for "Best Play" Stephen Karam when Stephen was seventeen and a winner in The Blank's Young Playwrights Festival. Henning has also been an acting teacher and coach and is known for his ability to spot young talent. He has given opportunities to many young actors who later went on to success in Hollywood including Tessa Thompson, Noah Wyle, Alison Brie, Molly Shannon, Academy Award winner Octavia Spencer, and Sarah Michelle Gellar. He coached Sarah Michelle Gellar on her auditions for the landmark TV series Buffy the Vampire Slayer, and they shared a close personal friendship, even traveling to Australia together with family for New Year's Eve 2000, where the paparazzi photographed Henning and Gellar dancing. For several months, Henning was rumored to be dating Gellar in the Australian fan magazines (including Big Hit Magazine), which, of course, was inaccurate as Henning was traveling with his husband, Rick Baumgartner. He is a graduate of NYU's Tisch School of the Arts, Circle in the Square Theatre School, and American Conservatory Theatre. His work for LGBTQ Equality includes creating the fiftieth Anniversary Celebration of the Black Cat Protests (the first major LGBTQ Demonstration in the US) and directing and hosting the 2017 LA City Council LGBTQ Pride Ceremony. He was recently honored by the CA State Legislature for his work in LGBTQ Equality and nurturing the future of the Arts. He has also narrated dozens of audiobooks, both nonfiction and fiction.
