Billy played a leading role in creating the Clean Energy Corps proposal to create 5 million new green jobs in the U.S., which was incorporated into the American Recovery and Reinvestment Act in 2009. He also helped to expand the AmeriCorps public service program to include a new “Clean Energy Service Corps”.

Billy grew up in New York City. He spent a semester of high school at The Mountain School in Vermont, where he was turned on to working for the environment. In July 2005 he led a three-day fast in front of the White House to draw attention to the 150,000 deaths caused each year by climate change.

In 2002, he dropped out of Yale University to help found the Energy Action Coalition, eventually renamed the Powershift Network. The Coalition became the largest youth-led clean energy advocacy network in the world, bringing together 50 environmental and social justice groups and over 340,000 members. It raised nearly $10 million in four years, helped get over 600 colleges to make commitments to climate neutrality, trained and empowered tens of thousands of young people, and worked to elevate climate issues in the 2008 elections.
