What to do if we run out of oil? I understand that electricy doesn't really rely on it that much, but our trains certainly carry the coal(40 percent of energy) and food certainly does. Should we decrease our need of coal and oil by going over to nuclear, wind and solar??? For transport maybe we can make "electric" trains that run on the energy grid? I"M talking about building nuclear and other means that don't have to rely on it. Can it be done and continue having the civilization that we have today.
