, coal overtook natural gas in 1990 and, despite some fluctuation, is set to be the second most used fuel in 2030 with just over 30q. It is predicted that natural gas will level off and remain relatively constant at about 25q. Nuclear and renewable energies all represented around 4q in 1980 and fluctuated up until 2008. It is speculated that nuclear
