What's happening with Bill Gates' multibillion-dollar energy fund?
Bill Gates believes the key to addressing climate change is an "energy miracle," and in November, he set about trying to conjure one. Flanked by President Obama and more than a dozen other world leaders in Paris for the first day of a landmark climate summit, Gates claimed a role for the private sector in delivering new solutions. But months have elapsed since the Microsoft Corp. co-founder and 27 other billionaires rolled out their Breakthrough Energy Coalition — a promise to invest billions of dollars with a long payback horizon on groundbreaking carbon-neutral technologies. And the group has barely been heard from since.
