We evaluate the greenhouse gas footprint of natural gas obtained by high-volume
hydraulic fracturing from shale formations, focusing on methane emissions. Natural gas
is composed largely of methane, and 3.6% to 7.9% of the methane from shale-gas
production escapes to the atmosphere in venting and leaks over the life-time of a well.
These methane emissions are at least 30% more than and perhaps more than twice as
great as those from conventional gas. The higher emissions from shale gas occur at the
time wells are hydraulically fractured -- as methane escapes from flow-back return fluids
-- and during drill out following the fracturing. Methane is a powerful greenhouse gas,
with a global warming potential that is far greater than that of carbon dioxide, particularly
over the time horizon of the first few decades following emission. Methane contributes
substantially to the greenhouse gas footprint of shale gas on shorter time scales,
dominating it on a 20-year time horizon. The footprint for shale gas is greater than that

...Although natural gas is promoted as a bridge fuel over the coming few decades, in
part because of its presumed benefit for global warming compared to other fossil fuels,
very little is known about the GHG footprint of unconventional gas… Fugitive emissions of methane are of particular concern. Methane is the major
component of natural gas and a powerful greenhouse gas. As such, small leakages are
important. Recent modeling indicates methane has an even greater global warming
potential than previously believed, when the indirect effects of methane on atmospheric
aerosols are considered (Shindell et al. 2009). The global methane...

Vt. utility calls for moratorium on renewable energy mandates

"VEC says until there are ways to overcome the hurdles surrounding renewables, natural gas is a good source of low carbon, base load power."

So this is the world we live in. The nukes sabotaging the natural gas guys. Then natural gas guys sabotaging the nukes. That is the economics we live in today, the players sabotaging each other, with these bad guys always wining by creating an artificial shortage.

I don't trust the lot of them...

What you are saying here is that you don't want to hear the truth because it inconveniences your personal scheme. Sure, why witness the truth when you can project hatred instead…the enemy of my enemy is my friend.

Nuclear breaks ice on Arctic gas shipments
07 December 2012

Russian nuclear-powered icebreakers have enabled the first ever LNG delivery via the Northern Sea Route from Norway to Japan, where it will go towards replacing generation lost from shut down nuclear reactors.

The Ob River carrier took Gazprom fuel from Hammerfest in Norway to the Japanese port of Tobata, taking nine days to travel the Northern Sea Route portion of the trip. Gazprom said there was little ice on the first half of the journey, but the second half saw fresh ice up to 30 centimetres thick. This was tackled by three icebreakers powered by small pressurized water reactors: the Vaygach, Rossiya, and 50 Let Pobedy

"the enemy of my enemy is my friend."
-which is BS in many instances like with Al Gore and the warmist alarmists, their enemy is the truth, and so the truth is definately my Friend.
The truth is that the earth's average temp hasn't increased at all in 15 years
