“The article, Ren, X., et al. (2017), “Methane emissions from the Marcellus Shale in southwestern Pennsylvania and northern West Virginia based on airborne measurements,” has been retracted by the authors because of an error in wind measurements used to calculate methane emissions in the southwestern Marcellus Shale region. The error was discovered by the authors in October 2017 upon their installation of an improved, differential GPS, wind measurement system onto the aircraft used in this study. The original wind measurements led to an overestimate of methane emissions from oil and natural gas operations. A reanalysis with corrected winds reduced the total estimated emissions by about a factor of 1.7, with a correspondingly larger reduction in emissions of methane attributed to oil and natural gas in the southwestern Marcellus Shale area. This is expected to reverse a conclusion of the paper, which had asserted that leakage from oil and natural gas extraction in this region results in a climate penalty compared to the use of coal. The authors are in the process of submitting a new manuscript based on an updated analysis that will describe the process to correct the erroneous wind measurements used in the original manuscript, provide a more accurate estimate of the methane emissions, and assess the implications of the fossil fuel production from the Marcellus Shale.”
Vladimir Putin said something funny and obvious about natural gas (or it should have been obvious if I lived in Russia)
“Russia should follow the lead of Gazprom and have more cars running on natural gas instead of traditional gasoline, according to President Vladimir Putin. It is cheaper and more eco-friendly, he said.
“Gas fuel is, of course, more environmentally friendly. And we have great competitive advantages in this because we have enough of this fuel. More oil and petroleum products can be sold on the foreign market, as it is more profitable than gas sales,” Putin said on Thursday, speaking at a meeting dedicated to the development of Russia’s regions.
Putin also pointed at Gazprom as an example of how gas fuel saves money. When the company switched to gas fuel, many of its drivers retired because they no longer had an opportunity to steal gasoline.
The president was referring to drivers working for state companies who commonly fill up using corporate credit cards, then siphoned and resold the petrol to other drivers.
“And what about the army? What is happening in the Ministry of Defense and in other departments? I think comments are needless,” said the Russian president, apparently hinting at the same practice.
“Natural gas fuel will have a huge positive economic effect and will create competitive advantages for the whole economy. Therefore, it is necessary to continue, of course, to support its development, both at the governmental level and at the regional,” Putin added.”
“A power plant burning wood chips will typically emit one and a half times the carbon dioxide of a plant burning coal and at least three times the carbon dioxide emitted by a power plant burning natural gas.
Although regrowing trees absorb carbon, trees grow slowly, and for some years a regrowing forest absorbs less carbon than if the forest were left unharvested.
Eventually, the new forest grows faster and the carbon it absorbs, plus the reduction in fossil fuels, can pay back the “carbon debt”, but that takes decades to centuries, depending on the forest type and use. We conservatively estimate that using deliberately harvested wood instead of fossil fuels will release at least twice as much carbon dioxide to the air by 2050 per kilowatt hour. Doing so turns a potential reduction in emissions from solar or wind into a large increase.”
Even The Guardian gets it …
This damagest the anti-frackers and anti-NG leaks groups.
“COLUMBUS, Ohio–A study of a Lake Erie wetland suggests that scientists have vastly underestimated the number of places methane-producing microbes can survive — and, as a result, today’s global climate models may be misjudging the amount of methane being released into the atmosphere.
In the journal Nature Communications, researchers at The Ohio State University and their colleagues describe the discovery of the first known methane-producing microbe that is active in an oxygen-rich environment.
Oxygen is supposed to be toxic to such microbes, called methanogens, but the newly named Candidatus Methanothrix paradoxum thrives in it.
In fact, 80 percent of the methane in the wetland under study came from oxygenated soils. The microbe’s habitat extends from the deepest parts of a wetland, which are devoid of oxygen, all the way to surface soils.
“We’ve always assumed that oxygen was toxic to all methanogens,” said Kelly Wrighton, project leader and professor of microbiology at Ohio State. “That assumption is so far entrenched in our thinking that global climate models simply don’t allow for methane production in the presence of oxygen. Our work shows that this way of thinking is outdated, and we may be grossly under-accounting for methane in our existing climate models.“
“The city of Las Vegas is now drawing 100 percent of its power from renewable energy sources“
“The effort moved closer to reality about a year ago when the city expanded its partnership with NVEnergy“
“NVEnergy’s GreenEnergy program allows large customers to contract for an added cost with the company to power their facilities. Customers that opt to receive all of their energy from renewable sources pay a slight premium for that.”
“Coal currently accounts for 8 percent of NVEnergy’s generating resources, compared with 74 percent natural gas and 18 percent renewable resources.”
Massive revenue guarantees for a handful of lucky wind power generators, but no appreciable environmental benefit from Ontario’s energy policies says economics professor Ross McKitrick
You may be surprised to learn that electricity is now cheaper to generate in Ontario than it has been for decades. The wholesale price, called the Hourly Ontario Electricity Price or HOEP, used to bounce around between five and eight cents per kilowatt hour (kWh), but over the last decade, thanks in large part to the shale gas revolution, it has trended down to below three cents, and on a typical day is now as low as two cents per kWh. Good news, right?
It would be, except that this is Ontario. A hidden tax on Ontario’s electricity has pushed the actual purchase price in the opposite direction, to the highest it’s ever been. The tax, called the Global Adjustment (GA), is levied on electricity purchases to cover a massive provincial slush fund for green energy, conservation programs, nuclear plant repairs and other central planning boondoggles. As these spending commitments soar, so does the GA.
In the latter part of the last decade when the HOEP was around five cents per kWh and the government had not yet begun tinkering, the GA was negligible, so it hardly affected the price. In 2009, when the Green Energy Act kicked in with massive revenue guarantees for wind and solar generators, the GA jumped to about 3.5 cents per kWh, and has been trending up since — now it is regularly above 9.5 cents.
In April it even topped 11 cents, triple the average HOEP.
So while the marginal production cost for generation is the lowest in decades, electricity bills have never been higher. And the way the system is structured, costs will keep rising.

Oh oh! Its going to be a cold winter in the UK!
The UK faces a looming winter gas supply crunch after Centrica said it has been forced to shut down a key gas storage facility until next spring.
Centrica’s Rough site accounts for more than 70pc of the UK’s total gas storage capacity, and can provide about 10pc of peak winter gas demand. The facility, which was converted from a partially depleted gas field off the Yorkshire coast in the 1980s, has suffered ongoing issues and outages in recent months and will now close entirely for further tests.
A spokesman said Centrica is working to see whether it will be possible to return around a third of the capacity to operation by November, in time for colder months when gas demand by energy companies climbs.
Cecile Langevin, a senior analyst with Thomson Reuters, said that even if companies are able to draw from the storage site before next March or April, Rough will only be 34pc full because the injections of gas usually made during the summer will not be possible .
Wholesale gas prices for this winter rocketed over 10pc on the UK market following the news, reaching 47½p a therm, as traders reacted to the announcement. The price closed at 46.65p a therm, the highest winter price in a year.
Fracking has really dropped the price of natural gas in the USA leading to major switch from coal to natural gas in power plants.
But China is resisting this change because of costs.
China’s effort to promote natural gas over coal to cut pollution is facing resistance from buyers who prefer cheaper to cleaner. The world’s largest energy consumer seeks to raise the share of less-polluting natural gas to 10 percent of its energy mix by 2020 from 6 percent last year. Yet even with the government cutting the cost of gas, it remains almost three times more expensive than coal when used to generate electricity. That’s putting a damper on the switch from a fuel that now accounts for more than 60 percent of demand.
Electricity generated from gas costs almost three times that from coal — about 0.6 yuan a kilowatt-hour in eastern China, while coal-fired output costs 0.22 yuan.
The Shanghai city-gate price — a wholesale cost of gas delivered to distributors — was cut in November to 2.18 yuan a cubic meter. That’s about $9 per million British thermal units, compared with $2.039 for U.S. benchmark prices and $4.24 in the U.K. as of Thursday.
Fracking is amazing.
A new report by the Energy Information Administration (EIA) found hydraulic fracturing, or fracking, has pushed carbon dioxide (CO2) emissions from electricity generation to the lowest levels since 1993.
Fracking created immense amounts of natural gas, lowering the price and causing the amount of electricity generated from natural gas to pass the amount of electricity generated from coal for seven of the months in 2015, according to the new EIA report. The report specifies that natural gas power plants produce about 40 percent of the CO2 emitted from a coal plant creating the same amount of electricity. This caused U.S. CO2 from the electricity sector to fall by 21 percent since their high in 2005.
“[T]he drop in natural gas prices, coupled with highly efficient natural gas-fired combined-cycle technology, made natural gas an attractive choice to serve baseload demand previously met by coal-fired generation,” read the report. “Coal-fired generation has decreased because of both the economics driven by cost per kilowatthour compared to that of natural gas and because of the effects of increased regulation on air emissions.”
