Gulf oil & gas disaster, fracking, media censorship & dirty gas threat to World

Correction: 1g CH4 has a greenhouse gas effect 105 times that of 1 g CO2 (and NOT as stated that 1 mole CH4 is 105 times worse GHG-wise than 1 mole of CO2).

For consequently revised calculaions see "Gas is not clean energy": https://sites.google.com/site/gasis....

The consequently revised conclusions are that:

1. 2.6 % leakage of CH4 yields the same greenhouse effect as the CO2 from burning the remaining 97.4% CH4.

2. With the existing power utility infrastructure in Victoria, Australia (in which gas burning yields half the CO2-e per MWh as brown coal buirmng):

a. At a leakage rate of 2.6% burning gas for power would yield 1.5 tonnes CO2-e/MWh (i.e. as dirty as the dirtiest coal-based power station Hazelwood’s 1.5 tonnes CO2-e/MWh).

b. At a leakage rate of 3.3% (US average) then burning gas for power would yield 1.73 tonnes CO2-e/MWh (1.2 times as dirty as Hazelwood).

c. At a leakage rate of 7.9% (the upper estimate with shale formation-derived gas) then burning gas for power would yield 3.2 tonnes CO2-e/MWh (roughly 2.1 times as dirty as Hazelwood).
