Which is why a short pipe from the well head to a close by power station makes sense rather than a massive, distribution network to individual homes.

It is, indirectly, with a GWP of 5.8.

Water vapour has a GWP of 0.001 and 0.0005 over 100 years.

It is easy to get GWP and radiative forcings mixed up.
