There have been some green initiatives to use ''non-fossil-fuel energy'' to crack methane. However, this is only worthwhile if the efficiency is better than non-methane-cracking ways to make hydrogen (see table). | There have been some green initiatives to use ''non-fossil-fuel energy'' to crack methane to make hydrogen gas.

Above 100%, you | Above 100%, you don't need any ''non-fossil-fuel energy'' for it to be green. Just burn some of the hydrogen to keep cracking the methane. Sadly, this has never been achieved. | ||
In the ideal case, fossil fuels could power the entire world with zero carbon emissions. At least, until [[peak oil|oil and gas reserves run out]]. | In the ideal case, fossil fuels could power the entire world with zero carbon emissions.
