3 Studies Confirm Shale Gas Is Not Worse Than Coal
For most of this year the enormous potential of shale gas has been clouded by controversy over its alleged climate impact. This began with the draft and later the leaked pre-publication version of a paper from a Cornell professor suggesting that the greenhouse gas emissions from gas were no better than those from coal and might even be...[read more]
EPA confirms high Natural Gas leakage rates
The latest EPA study confirms that its original "seminal" study of methane leaks from natural gas use, i.e. "Methane Emissions from the Natural Gas Industry (GRI/EPA 1996) was in error. The GRI/EPA 1996 study was the holy grail. The IPCC used GRI/EPA numbers when it assessed the climate impact of gas. The old figures...[read more]
Gas: the bridge to nowhere?
I corresponded with Dr. Robert Howarth since I posted an article about his research into the climate impact of gas here last week. Howarth is the scientist who is saying gas has a greater climate impact than coal. Howarth emailed to say his opinion is based on several points. One, the latest research indicates...[read more]
Natural Gas. Green? Perhaps NOT.
“Using the best available science, we conclude that natural gas is no better than coal and may in fact be worse than coal in terms of its greenhouse gas footprint when evaluated over the time course of the next several decades.” This is the recently posted conclusion of Dr. Robert Howarth, David Atkinson Professor of Ecology and...[read more]

“Negative pricing if it was wide spread it would be quickly fixed by the utilities who would simply choose to dunp excess electricity via perhaps joule heating rather than sell it at a loss.”
“These artificial leaf researchers get lots of headlines, but could they really be cost competive with normal solar panels connected to normal electrolysis units? Interconnecting a large area with plumbing for water and hydrogen will like cost more than interconnect with electrical wire. Then there is the giant lead in efficiency that normal PV solar cells have over these new PEC ...”
