"Everybody talks about climate change, but nobody is taking serious action. One big reason is economics. Reducing the buildup of carbon dioxide in the atmosphere—the major human-based driver of climate change—requires an expensive shift away from coal and oil as our prime sources of energy. Or it requires costly technology to capture CO2 as industry emits it and then store the gas where it will stay put for centuries to come. Yet what if a technology could economically do both: produce large amounts of energy and significantly reduce greenhouse gas emissions?" (Quoted from article)
