Join Dr. Scott Tinker on an unexpected journey -- in turns heart-warming, funny, eye-opening and unsettling -- to understand the benefits and challenges of bringing energy to more than 3 billion citizens of the developing world. In this spectacular 6-part series, he'll cross Nepal with an environmental health scientist, studying people's transition from the most dangerous cooking fuel, killing millions a year, to the safest; visit Ethiopia's huge new hydroelectric dam and Kenya's largest slum, to see how Africa will power its people; venture into the ports and coal mines that support a growing Vietnam; and install a solar microgrid to bring electricity, for the first time ever, to the Arhuaco people of Colombia.
