From Barack Obama’s commencement speech at Wesleyan University, 25 May 2008 (he was standing in for Ted Kennedy):

At a time when our ice caps are melting and our oceans are rising, we need you to help lead a green revolution. We still have time to avoid the catastrophic consequences of climate change if we get serious about investing in renewable sources of energy, and if we get a generation of volunteers to work on renewable energy projects, and teach folks about conservation, and help clean up polluted areas; if we send talented engineers and scientists abroad to help developing countries promote clean energy.

That last sentence is a reference to two graduating Wesleyens who are heading to Kenya with biogas digesters.
