Almost every way we make electricity today puts out CO2. So what we're going to have to do at a global scale is to create a new system. And so we need energy miracles. Usually we don't have a deadline where you have to get the miracle by a certain date. Usually you just kind of stand by， and some come along， some don't. This is a case where we actually have to drive full speed and get a miracle in a pretty tight time line.
