Former Chairman and CEO of Chesapeake Energy Corporation
Not Clearly Pro or Con to the question "Can Alternative Energy Effectively Replace Fossil Fuels?"
"[W]e don’t need a new fuel, we don’t need new engine technology, we don’t need hundreds of billions of dollars. All you have to do is modify or replace today’s internal combustion engines that run on gasoline and diesel and replace them with an internal combustion engine that runs on natural gas."
