What type of renewable fuel will emerge as the low carbon solution for commercial transportation? How do you make the case for renewable energy in light of inexpensive natural gas? How does a neighborhood business association structure a community solar project? These were some of the questions being considered by over a hundred experts and leaders at the Renewable Energy Challenge during the GLOBE Conference and Innovation Expo this March. With over 10,000 investors, buyers, policy makers and leaders from around the world meeting to shape future markets, test policy approaches, strike deals and collaborate, the conference held in Vancouver, Canada, presented a pivotal opportunity for the world to take real, tangible action on climate change following the United Nations Conference on Climate Change.
