While natural gas offers clear
advantages over coal, over-relying on it for electricity creates serious economic and public health risks for consumers and states and fails to provide a long - term solution to climate change.
However, the report also warned that while natural gas has carbon
advantages over coal as a fuel source, the potential for leakages of methane may erode this benefit, as methane is a more potent greenhouse gas.
Methane lawsuit threat hangs over EPA's head Research by the Environmental Defense Fund has found that leakage rates must remain below 3.2 percent for natural gas power plants to carry a climate
advantage over coal plants.
Natural gas might still have
an advantage over coal when burned to create electricity, because gas - fired power plants tend to be newer and far more efficient than older facilities that provide the bulk of the country's coal - fired generation.
But, again, the notion that gas holds
no advantage over coal, in weighing the climate implications of energy choices, is fading fast (to my reading of the science and that of many others).
ProPublica has published a good update on concerns that existing practices for extracting and piping natural gas, through leakage, substantially cut into the fuel's substantial greenhouse - gas
advantage over coal.
Also, if fugitive methane emissions exceed 3 percent of total gas production, natural gas's climate
advantage over coal disappears over a 20 - year time horizon.
Weiss said that, while natural gas burns cleaner, the NETL study concluded that the end - to - end emissions involved in moving U.S. natural gas to an LNG export facility, then liquefying it, then shipping it across the ocean, then de-liquefying it, and shipping it to users in other countries, would be as energy and emissions intensive, or more, than using regionally produced coal — i.e., because of the LNG export supply chain, it has
no advantage over coal.
Anthony Hobley, CEO Carbon Tracker: «Fugitive emissions are on the run in the U.S. — regulators, investors and industry leaders are all out to ensure gas can demonstrate it has a climate
advantage over coal»
«Fugitive emissions are on the run in the U.S. — regulators, investors and industry leaders are all out to ensure gas can demonstrate it has a climate
advantage over coal,» said Anthony Hobley, CEO of Carbon Tracker.

It will only be challenged by nuclear in specific circumstances, and
coal has significant
advantages over nuclear, as well as alternatives such as hydro and renewables.
With
coal, the plants are cheap to build, the
coal is cheap to mine, and a «natural monopoly» system of electricity generation and distribution helps lock out any renewable competition, leading to further economic
advantages over renewables.
First, utilities used to build power plants right next to
coal mines, so some of the oldest plants can have an
advantage over newer models.
The industry touts the amount of potential energy that can be gained from a fracking well relative to its «small» footprint as a major

That's another strike against those, including a Cornell academic, who argue that so - called fugitive emissions from unconventional natural gas production offset the emissions
advantages natural gas has
over coal in power generation.
This quick - start capability confers wind farms a decided
advantage over thermal
coal and natural gas — fired power plants when it comes to balancing electricity supply and demand.
Fukushima presented an opportunity for AGL Energy because it meant that Tepco, the plant's operator, was no longer in a position to invest in Loy Yang A and was a distressed seller of its one third stake in Loy Yang A. AGL Energy, which already had a 32.5 per cent stake in the plant, says Loy Yang A will remain one of the lowest cost generators in the NEM because of cheap
coal at the doorstep — it pays just $ 6 / t for brown
coal, which would give it a massive
advantage over black
coal generators in NSW, which are facing costs of $ 45 / t and will go higher in future years.
Gasoline,
coal, and natural gas usage will inevitably decline as carbon's cost
advantage over alternatives lessens or disappears.
More quietly (but in many ways worse), leaking wells, pipes, and storage reservoirs are estimated to emit enough greenhouse gases to cancel out the climate
advantages of burning gas
over coal, and increase smog.
Methane has the
advantage over oil and
coal of producing less carbon dioxide gas when burned.
Methane leakage diminishes the climate
advantages of natural gas
over coal.
In Australia at least, the operators of
coal fired power stations have two unfair economic
advantages over sustainable electricity:
Not only is this a substantial quantity of product vanishing into the air (natural gas is primarily methane), it is also significantly higher than most previous estimates — including from industry — and would reduce or eliminate any
advantage natural gas has
over coal from a climate standpoint.
Methane is at least 34 times more potent a greenhouse gas than carbon dioxide, so methane leakage erodes the climate
advantage natural gas has
over coal.
