Funny Euen, In the past I have asked the odd question about net energy but as I never received much of a response so I felt that I must not be asking in an understandable manner. One question in particular was merely a simple one as to how the world total consumption was totalled. For example, using the figure above of 84mb/d, is that net or gross? If net what does the gross total? If gross what was the total less that needed for production. (maybe no quantified answer to that but I think a 'gross' view would still be 'one' into the 'net' of greater general understanding)

Kristil,


Its a good question. I suspect there is no universal answer. The UK and Norwegian governments publish stats that provide some indication of the energy used to produce fuel.

But relating these stats to the ones we normally use from IEA, BP et al is not straight forward. The data exists, but there is a PhD research project in there accessing it, untangling it and interpreting it.

The chart shows UK nat gas used in energy industries - actually declining as our energy industry has declined. Measured by off shore installations being decommissioned.

Not very satisfactory I know.

Uean, thank you for your response and for considering the question a good one ... so much for me considering it a simple one though.

But on a truly simple item, today my son came up from the basement to tell me that the unused, for two years, dehumidifier was still up and running. I guess it has been dehumidifying like a trooper all that time and then automatically stopping when full and then evaporating till... and etc. for two years! Good thing we haven't invented the energy conservation police yet.
