Coal, like it or not, will be a global source of energy FAR beyond our lifetimes, well into the next century. Simply SO much energy locked up in those complex hydrocarbons to ignore. Americal has easily enough coal to last 600 or 700 years at current rates of consumption. So, relax: there is room for coal, NG, oil, wind, solar in the energy mix.
Have a nice week !!
