Yes. The comparisons of CO2 output aside, methane mining is increasingly being shown to be a major contributor to methane in the atmosphere. Being a far more potent greenhouse gas than carbon dioxide, we need to minimise the production of methane, rather than increase it. https://www.theguardian.com/environment/2016/oct/26/what-is-causing-the-rapid-rise-in-methane-emissions https://www.theguardian.com/environment/2016/oct/26/what-is-...
As far as renewables go we have options including wind power which are already cheaper than natural gas plant: https://cleantechnica.com/2016/12/25/cost-of-solar-power-vs-cost-of-wind-power-coal-nuclear-natural-gas/ https://cleantechnica.com/2016/12/25/cost-of-solar-power-vs-...
So both from economic and ecological viewpoints, natural gas is a bad idea.
- mirimir 8y agoBut still better overall than coal, perhaps?
- manicdee 8y agoIf you are switching away from coal, the economically sensible decision is renewables. The ecologically sensible decision is also renewables. Switching to gas is just trading one version of disaster for another. Instead of your world being razed by Godzilla you spend lots of money so it gets razed by Hedorah instead.
- adrianN 8y agoBut coal and renewables are very different, unless you also buy lots of storage.
- manicdee 8y agoThe issue has been done to death in academic circles. All we need to do is stop subsidising coal and nuclear, focus on investing in (companies rolling out) renewables, and let the propeller heads get the job done. Here's one recent take on the issue: https://reneweconomy.com.au/a-100-renewable-grid-isnt-just-feasible-its-already-happening-73505/ https://reneweconomy.com.au/a-100-renewable-grid-isnt-just-f... Note that last bit: as we shift to a transport fleet consisting of more and more EVs, the possibility of using storage to balance out demand vs supply becomes more likely, without huge investment in utility scale static batteries.
- Baeocystin 8y agoNo perhaps about it. Natural gas is far better a fossil fuel to burn than coal per BTU. Still not ideal, of course. But it absolutely has its place as a transition fuel as we work to decarbonize our energy production.
- manicdee 8y agoFor the same money we can build solar and wind plant faster than gas, with the benefit of not using fossil fuels and increasing the rate of greenhouse gas emissions. Methane is not a transition fuel, it is simply a smoke and mirrors truck replacing some of the CO2 emissions of coal with methane emissions from well to furnace. Methane is far worse than carbon dioxide, we should not be following plans to increase methane emissions for a token reduction of CO2 emissions.
- throwahey 8y agoConsider me ignorant in this topic, but doesn't coal throughput beat out Solar or Wind? As far as I know you can always burn coal where as wind and solar are limited by external factors.
- __s 8y agoRenewables which have jitter in their throughput can be made consistent with batteries https://thinkprogress.org/colorado-wind-batteries-cheap-12e82b91a543 https://thinkprogress.org/colorado-wind-batteries-cheap-12e8...
- manicdee 8y agoThere are also pumped hydro and flywheels, amongst other options for storage with various optimum characteristics.
- Baeocystin 8y agoYou don't deserve to be downvoted for your statement, as it is correct- coal plants can function 34/7, unlike most other green sources other than geothermal. Of course, gas plants can also function continuously, and for baseline, nothing beats nuclear. But burning gas for energy is far better than just releasing it unburned in to the air, or flaring it for no productive purpose. As we get more large-scale batteries online, the variable output of things like wind and solar will matter less, and they will be able to provide an ever-increasing percentage of our energy mix. This is well underway, but it is a huge task that will take a long time to complete.
- manicdee 8y agoA 100% renewable grid is possible by over-deploying renewable capacity, and providing time of production and time of use smoothing through storage. Solar is particularly good at addressing daily peaks because those peaks generally happen during the day. Wind is good at relatively steady production around the clock because there is almost always wind blowing somewhere. Coal is pretty terrible because it takes hours to react to changes in demand. This is why we have the term “baseload”: the rest of the industry must be highly dispachable to work around the high thermal mass (and resultant low responsiveness) of coal plants. In addition coal plant tends to be large monolithic production, so the loss of one plant represents a significant proportion of supply. Coal is thus a net hazard to power reliability.
