With nearly $ 100 billion to his name, Microsoft co-founder and philanthropist Bill Gates has an intimidatingly large heap of funds to deploy.
The Gates Foundation has invested $ 10 billion in energy projects in the developing world, the return would have been $ 150 billion, Gates says. Infrastructure investment in the developing world would have returned $ 170 billion.
"By investing in global health institutions, however, we have exceeded all of those returns," Gates writes.
"Institutions such as Gavi, the Global Fund and GPEI are the closest things we have to surefire bets to alleviate suffering and save lives," he writes in the Journal. "They are the best investments that Melinda and I have made over the past 20 years, and they are some of the best investments the world can make in the coming years."
