Similarly to the first summit, it included workshops, panel discussions, and speakers focusing on addressing climate change and environmental justice. Casper ter Kuile the co-director of the UK Youth Climate Coalition states that it is more than a youth movement, it is "social movement" . This time, keynote speakers included Van Jones, Bill McKibben of 350.org, Ralph Nader, and Speaker of the House Nancy Pelosi. The third American Power Shift took place April 15 to 18, 2011, in Washington, D.C., at the Walter E. Washington Convention Center. The conference had over 10,000 attenders. People came to support various environmental movements, many in protest of President Barack Obama's alleged weakness on environmental issues. Guest speakers included former U.S. vice-president Al Gore, Greenpeace Executive Director Phil Radford, and environmental advocate Van Jones. The fourth Power Shift conference in the US was also the first outside of Washington. It was instead held in Pittsburgh, Pennsylvania, at the David L. Lawrence Convention Center on October 19–21, 2013. Keynote speakers included Gasland director Josh Fox, Sierra Club director Michael Brune, and Kandi Mossett of the Indigenous Environmental Network. The program included a rally against coal production and the organization of protests against the Keystone XL Pipeline. The 2006 PowerShift Conferences In 2006, a series of student conferences on energy security were organized under the name PowerShift by the 20/20 Vision Education Fund, a 501(c)3 organization based out of Maryland. (They were not affiliated with the 2007 and later Power Shift conferences organized by the Energy Action Coalition.) Over 250 people participated in the first conference which took place in Kalamazoo, MI on April 1, 2006, and featured former Central Intelligence Agency director Jim Woolsey giving a keynote speech on U.S. oil dependence and national security. The conferences also featured a simulated energy wargame called Oil Shockwave, developed by non-profit groups Securing America's Future Energy (SAFE) and the National Commission on Energy Policy.
