Climate One speaks to John Hofmeister and Bill McKibben on energy waste management. "I'm a strong advocate of moving away from the internal combustion engine," says former president of Shell Oil, John Hofmeister while founder of 350.org counters saying that, "the reason we haven't made that transition is because we lack the technology, it's because the fossil fuel industry has made sure that we keep the price of fossil fuel artificially low. This is the only industry in the world that doesn't have to pay to take out their waste."
