For some time it has been assumed that reducing greenhouse gas (GHG) emissions will require a shift to cars that do not use petroleum and to power plants that do not use coal, because of the emissions from these sources. All of this may be a false alarm.
Two recent articles indicate that there may be no need to reduce petroleum use in cars to reduce greenhouse gas emissions (GHG). The first story from USA Today describes a new process for producing gasoline from CO2. If implemented, this could materially reduce GHG emissions from coal fired electricity plants – a principal source of GHG emissions in the United States and in many other nations, including China and India. Another story in The New York Times, indicates the potential of technology that could capture CO2 emissions from cars, to be later refined into gasoline. All of this is further evidence that technology is the answer with respect to reducing GHG emissions.
