Reducing CO₂ Emissions: Turn Down the Heat, Crank Up Efficiency Free

The authors confined their discussion of reducing carbon dioxide emissions to end uses, and therefore did not discuss energy generation. However, they should have mentioned the possibility of operating the railroads, and perhaps automobiles, with electricity generated by nonpolluting methods, such as nuclear, wind, or solar power, instead of burning fossil fuels in internal combustion engines. Already a major part of the electricity running the railroads in western Europe is nuclear generated. In France it amounts to 75%. ¹
