This week, President Obama joined 19 other world leaders in launching Mission Innovation — an initiative to dramatically accelerate public and private global clean energy innovation to address global climate change, provide affordable clean energy to consumers, including in the developing world, and create additional commercial opportunities in clean energy. To complement this effort, Bill Gates is spearheading the Breakthrough Energy Coaltion, a private sector-led effort that has pledged to invest extraordinary levels of private capital in clean energy, focusing on early-stage innovations.
